Description

[Technical Field]

[0001] The present invention relates to playing cards. [Background technology]

[0002] Playing cards are used all over the world in a variety of games, magic tricks, fortune telling, and so on. As is well known, a standard deck of cards consists of 52 cards with unique combinations of four suits (suits) - spades, hearts, clubs, and diamonds - and 13 ranks (scores) (1 to 13), plus one or two joker cards.

[0003] Each card is rectangular, and when viewed with the two long sides facing left and right, the front of each card (except the Joker) has an index on the upper left side (rear side) and lower right side (front side) that combines the suit shape of each card with a number (2 to 10) or symbol (A (= 1), J (= 11), Q (= 12), K (= 13)) that represents the card's rank.

[0004] Also, on the front of each card, cards with ranks 1 to 10 have the figure of a suit equal to the number of their ranks, while cards with ranks 11, 12, and 13 have the pictures of a Jack, Queen, and King, respectively. For this reason, cards with ranks 11, 12, and 13 are also called picture cards.

[0005] In addition to such general playing cards, various playing cards are known that are designed in various ways to suit specific uses and purposes (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2004-163743 Summary of the Invention [Problem to be solved by the invention]

[0007] As mentioned above, playing cards are used in a variety of games around the world. For example, there are games such as baccarat, which is played in casinos, in which cards are dealt face down so that the suits and ranks of the cards on the front side cannot be seen, and then players turn their cards face up, and the outcome is decided based on the suits and ranks of their own cards and their opponents' cards.

[0008] When turning over a card, players may slowly turn over the card from the edge (squeezing motion) so that the suit and rank on the front of the card are gradually revealed, while hoping to win. By turning over the card slowly, the sense of thrill increases due to the tension and excitement until the winner is decided, and this is one of the joys of card games.

[0009] However, with picture cards, once you start turning over the cards, the pictures of Jack, Queen, and King become visible and the ranks of the cards become clear, so the tension and excitement of the game participants ends in a short time.

[0010] Therefore, an object of the present invention is to provide playing cards that allow users to enjoy squeezing actions even more in card games such as baccarat. [Means for solving the problem]

[0011] The playing cards that solve the above problem have a plurality of cards that are uniquely combined with a plurality of suits and a plurality of ranks, and on the front of each of the plurality of cards, the figures of the suits of the number equal to the respective ranks are displayed. The plurality of cards are rectangular in shape, and each card has a rank of 1 to 13. On the front surface of a card assigned a rank of 11, 12, or 13, a group of first figures representing the suit of the card, the number of which is two less than the rank of the card, is displayed at a position where a first reference line parallel to and equidistant from the two long sides of the card intersects with a second reference line parallel to and equidistant from the two short sides of the card, and one second figure representing the suit of the card is displayed on each side of the group along the first reference line. are.

[0012] Other problems and solutions disclosed in the present application will be made clear in the detailed description and drawings. [Effects of the Invention]

[0013] According to the present invention, the user can enjoy the squeezing operation even more in a card game such as baccarat. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described in detail. Note that the following embodiments and modifications are merely examples for explaining the present invention, and are not intended to limit the present invention to only these embodiments. Furthermore, the present invention can be modified in various ways without departing from the gist of the invention. Furthermore, those skilled in the art will be able to adopt embodiments in which the elements described below are replaced with equivalents, and such embodiments are also within the scope of the present invention.

[0016] First, the terms used in this application will be explained.

[0017] "Playing cards" refers to a set (deck) of cards that has multiple cards with a unique combination of multiple suits and multiple ranks. The playing cards described in this embodiment include at least 52 cards with a unique combination of four suits and 13 ranks, and may further include one or two joker cards. Of the multiple cards that make up the playing cards described in this embodiment, the cards with ranks 2 to 10 and the joker cards have the same face designs as the general playing cards described above, so detailed descriptions of these cards will be omitted.

[0018] "Suit": refers to the figure (mark) assigned to each card. The playing cards described in this embodiment have four suits, spades, hearts, diamonds, and clubs, just like regular playing cards, but other figures may also be used. Suits are also referred to as suits.

[0019] "Rank": A numerical value assigned to each card. In the playing cards described in this embodiment, there are ranks from 1 to 13. Cards with ranks 2 to 10 are indicated by numbers 2 to 10, and cards with ranks 1, 11, 12, and 13 are indicated by letters A, J, Q, and K, respectively. Ranks are also referred to as scores. In addition, all cards (52 cards) in the playing cards described in this embodiment, except for the jokers, have suit figures of the number equal to their respective ranks displayed on their fronts. For this reason, the playing cards described in this embodiment do not include face cards, except for the jokers.

[0020] "Card type": The type of a card is identified by the "suit" and "rank" displayed on the surface of the card, such as "Ace of Spades" or "Seven of Hearts." In this specification, the combination of "suit" and "rank" is referred to as the "card type."

[0021] "Index": When you look at a card with the two long sides facing left and right, the symbol that indicates the card type is displayed at the top of the left side (rear side) or the bottom of the right side (front side), or both.

[0022] "Baccarat": A card game exemplified in this embodiment, in which users bet on the winner of a card game between a banker (house) and a player (customer). The dealer deals two or three playing cards to each of the banker and player in accordance with the rules of the game, and the player whose first digit of the total rank of the dealt cards is closest to "9" wins. Cards with ranks 11 to 13 are counted as 0.

[0023] "Squeezing action": Starting with a card face down so that its face cannot be seen, cover the index part of the card with your fingers, then bend the card and gradually turn over the edge to gradually see the suit pattern on the face. If the card is rectangular, there are "diagonal squeezing" where you turn over from a corner, "vertical squeezing" where you turn over from a short side, and "horizontal squeezing" where you turn over from a long side.

[0024] Next, the front designs of each card 110 of the playing cards 100 according to this embodiment are illustrated in Figs. 1 to 4. Fig. 1 shows the spade cards 110 numbered 1 to 13, Fig. 2 shows the heart cards 110 numbered 1 to 13, Fig. 3 shows the diamond cards 110 numbered 1 to 13, and Fig. 4 shows the club cards 110 numbered 1 to 13. The backs of each card 110 are displayed with a back pattern 400 as illustrated in Fig. 16, but as this is common to all cards 110, a detailed description thereof will be omitted. As for the joker card 110, the front design is arbitrary, and a detailed description thereof will be omitted.

[0025] As shown in Figures 1 to 4, the playing cards 100 according to this embodiment have 52 cards 110 that are unique combinations of four suits and 13 ranks, and the faces of all 52 cards 110 are marked with the shapes of the suits, the number of which is equal to the respective ranks.

[0026] That is, the front of the cards 110 numbered 1 to 10 of each suit displays the figures of each suit, and the front of the cards 110 numbered 11, 12, and 13 display the figures of each suit, 11, 12, and 13, respectively, instead of pictures such as Jack, Queen, and King.

[0027] 5, for example, in the case of the spade 11 card 110, a group 210 of first figures 211 representing the suit (spade) of the card 110, whose number is equal to 9 (11, the rank of the card 110, minus 2), is displayed at the position (center of the card 110) where a first reference line 140 parallel to and equidistant from the two long sides 120 (first long side 121 and second long side 122) and a second reference line 150 parallel to and equidistant from the two short sides 130 (first short side 131 and second short side 132) intersect. Furthermore, two second figures 220 representing the suit (spade) of the card 110 are displayed on both sides of the group 210 along the first reference line 140. Specifically, these two second figures 220 are displayed in the same positions as the two suit figures displayed on the card 110 whose rank is 2.

[0028] Here, the second figure 220 is the same (same shape and size) as the suit figure displayed on each card 110 of ranks 1 to 10. The first figures 211 constituting the set 210 are the same size as each other and have the same shape as the second figure 220, but are set to be smaller than the second figure 220.

[0029] Furthermore, the width W21 (length along the second reference line 150) of the assembly 210 is determined to be approximately equal to the width W1 of the second figure 220. For example, W21 is determined to be the same value as W1 (W21 = W1), or within a predetermined range (for example, within ±5%) of W1. Furthermore, the height H21 (length along the first reference line 140) of the assembly 210 is determined to be approximately equal to the height H1 of the second figure 220. For example, H21 is determined to be the same value as H1 (H21 = H1), or within a predetermined range (for example, within ±5%) of H1.

[0030] Within a rectangular area of ​​width W21 and height H21, a total of nine first figures 211 are aligned and displayed in three rows vertically (along the first reference line 140) and three columns horizontally (along the second reference line 150).

[0031] This configuration allows the user to visually recognize a single aggregate 210 made up of multiple first figures 211 as if it were a single figure, making it possible to display the aggregate 210 and the second figure 220 on the surface of the card 110 without creating a sense of incongruity.

[0032] Next, the 12 spades card 110 is shown in Fig. 6. The 12 spades differs from the 11 spades in that the set 210 is made up of ten first figures 211.

[0033] In the case of the 12 spades, the size of the group 210 is also determined to be within a predetermined range based on the second figure 220, but since the group 210 of the 12 spades is made up of ten first figures 211, one more than the group 210 of the 11 spades, the size of the group 210 of the 12 spades is larger than the size of the group 210 of the 11 spades.

[0034] Specifically, the width W22 (length along the second reference line 150) of the group 210 in the case of the spade 12 is set to be approximately equal to the width W1 of the second figure 220. For example, W22 is set to be the same value as W1 (W22 = W1) or within a predetermined range (e.g., ±5%) of W1. The height H22 (length along the first reference line 140) of the group 210 is also set to be approximately equal to the height H1 of the second figure 220, but is set to be slightly longer than H21 (e.g., H22 = (4 / 3) × H21).

[0035] Within a rectangular area of ​​width W22 and height H22, three first figures 211 are displayed in a row vertically (along the first reference line 140), four first figures 211 are displayed in a row vertically, and three first figures 211 are displayed in a row vertically (along the second reference line 150) in that order.

[0036] Next, the 13 of spades card 110 is shown in Fig. 7. The 13 of spades differs from the 11 of spades in that the set 210 is made up of 11 first figures 211.

[0037] In the case of the 13 spades, the size of the group 210 is also determined to be within a predetermined range based on the second figure 220, but the group 210 of the 13 spades is made up of 11 first figures 211, two more than the group 210 of the 11 spades, and the size of the group 210 of the 13 spades is larger than the size of the group 210 of the 11 spades.

[0038] Specifically, the width W23 (length along the second reference line 150) of the group 210 in the case of the spade 13 is set to be approximately equal to the width W1 of the second figure 220. For example, W23 is set to be the same value as W1 (W23 = W1) or within a predetermined range (e.g., ±5%) of W1. The height H23 (length along the first reference line 140) of the group 210 is also set to be approximately equal to the height H1 of the second figure 220, but is set to be slightly longer than H21 (e.g., H23 = (5 / 3) × H21).

[0039] Within a rectangular area of ​​width W23 and height H23, three first figures 211 are displayed in a row vertically (along the first reference line 140), five first figures 211 are displayed in a row vertically, and three first figures 211 are displayed in a row vertically, in that order, horizontally.

[0040] Alternatively, it is also possible to set the height of the rectangular area as H23 = (4 / 3) × H21, and display four first figures 211 arranged in a vertical line, three first figures 211 arranged in a vertical line, and four first figures 211 arranged in a vertical line in this area, all arranged in that order horizontally. In this case, the size of the group 210 of 13 spades can be made equal to the size of the group 210 of 12 spades.

[0041] The above explanation is about the spade cards 110 of 11, 12, and 13, but the same applies to the hearts, diamonds, and clubs cards 11, 12, and 13, and therefore explanations about these cards 110 will be omitted.

[0042] In this way, the playing cards 100 according to this embodiment have suit figures of the number equal to the rank of each card displayed on the front of all 52 cards 110. This allows the user to enjoy the thrill of the squeezing action even more when a Jack, Queen, King, or other pattern appears and the user does not immediately know that the rank is 11, 12, or 13, when playing a card game such as Baccarat.

[0043] As shown in Figures 1 to 4, the suit figure (second figure 220) of the card 110 of rank 1 (A) of the playing cards 100 according to this embodiment is not displayed in the center of the card 110 (near the intersection of the first reference line 140 and the second reference line 150), but in a position close to one of the short sides 130 (first short side 131) from the center of the card 110 (the same position as one of the two suits displayed on the card 110 of rank 2).

[0044] In this manner, as will be described in more detail below, when a user squeezes a card 110 of rank 1, depending on the orientation of this card 110, it will appear the same as a card 110 of rank 2 or 3, allowing the user to enjoy the thrill of the squeezing action even more.

[0045] Next, with reference to FIGS. 8 to 14, how the suits on the front side appear when performing a squeezing operation using the playing cards 100 according to this embodiment will be described.

[0046] FIG. 8 is a diagram showing an example of how the card 110 is squeezed (bent) when the user performs the squeezing operation. FIG. 8 shows the front side of the card 110, but when the user performs the squeezing operation, the card 110 is placed on the desk with its back side facing up so that the front side is not visible. In this state, the user picks up the end of the card 110 (the lower left part of FIG. 8) and gradually turns over the cards 110 in the order of S0 to S4. Note that FIG. 8 exemplarily shows the front side of a card 110 with a total of seven hearts in the suit, i.e., the "seven of hearts," while FIGS. 9 to 14 exemplarily show the front side of a diamond card.

[0047] First, FIG. 9 shows how each card looks when a user performs a narrowing operation to S0 using a general playing card different from the playing card 100 according to this embodiment.

[0048] As shown in FIG. 9, in the case of typical playing cards, the pictures of "J" (Jack), "Q" (Queen), and "K" (King) cards (face cards) are recorded close to the edge of the card. On the other hand, the suits of cards ranked 1 to 10 are recorded inside the outline of the pictures. Therefore, when the "squeezing operation" is performed from the corner of the card to the S0 position, part of the picture of a face card (J, Q, or K card) becomes visible at first, but nothing of cards ranked 1 to 10 is visible. Therefore, as shown in FIG. 9, if the picture is not visible when the "squeezing operation" is performed to the S0 position, it can be determined that the card is one of the cards ranked 1 to 10. However, if the picture is visible, it is immediately clear that the card is ranked "J," "Q," or "K."

[0049] In contrast, as shown in Fig. 10, in the case of the playing cards 100 according to this embodiment, when the user performs the squeezing operation up to S0, the suit of the face up card is not visible for any of the cards 110 ranked 1 to 13. Therefore, the user can enjoy the thrill of the squeezing operation for a longer period of time, even when the cards are ranked 11 to 13. In Fig. 10, even if the top and bottom of the diamond 1 card 110 are reversed, the suit of the face up card is not visible.

[0050] Next, FIG. 11 shows the state of each card 110 when the user performs a squeezing action to S1 using the playing cards 100 according to this embodiment.

[0051] As shown in Figure 11, for cards 110 ranked 4 to 10, two suit figures are displayed along the short side 130 of the card (with legs). On the other hand, for cards 110 ranked 1, 2, 3, 11, 12, and 13, a suit figure is displayed in the center of the card 110 along the long side 120 of the card 110 (i.e., on the first reference line 140) (without legs).

[0052] Therefore, when the user performs the "squeezing operation" from position S0 to S1, part of the suit of cards with ranks 4 to 10 will appear to have "legs," while cards with ranks 1, 2, 3, 11, 12, and 13 will appear to have "no legs."

[0053] Therefore, as shown in Fig. 11, at the timing when the "squeezing operation" is performed up to S1, if there is a "leg", the rank of the card 110 can be determined to be any of 4 to 10, and if there is no leg, the rank of the card 110 can be determined to be any of 1 to 3 or 11 to 13. In Fig. 11, even if the top and bottom of the diamond 1 card 110 are reversed, the suit of the face up cannot be seen.

[0054] Therefore, even if the narrowing operation is performed up to S1, the user cannot yet identify the rank of each card 110, and the user can enjoy the thrill of the narrowing operation.

[0055] FIG. 12 shows the state of each card 110 when the user performs the squeezing action up to S2 using the playing cards 100 according to this embodiment.

[0056] As shown in FIG. 12, for cards 110 ranked 9 or 10, four suits are recorded along the long side 120 of the card 110 (four pins). For cards 110 ranked 6 to 8, three suits are recorded along the long side 120 of the card 110 (three pins). For cards 110 ranked 4 or 5, two suits are recorded along the long side 120 of the card 110 (two pins). For cards 110 ranked 1, 2, 3, 11, 12, and 13, suits are recorded on a first reference line 140 in the center of the card 110, parallel to the long side 120 of the card 110 (vertical).

[0057] Therefore, when the "squeezing operation" progresses from position S1 to S2, the bottom two suits of the "4 pin" suit become visible for cards 110 ranked 9 or 10, and the bottom suit and part of the middle suit of the "3 pin" suit become visible for cards 110 ranked 6 to 8. The "2 pin" suit becomes visible for cards ranked 4 or 5, and part of the bottom suit of the "vertical" suit becomes visible for cards 110 ranked 2, 3, 11, 12, and 13. Furthermore, for cards 110 ranked 1, if the suit is positioned as shown in FIG. 12, the suit is not visible, but if the card 110 is upside down, part of the suit becomes visible, just like cards 110 ranked 2, 3, 11, 12, and 13.

[0058] Therefore, as shown in Figure 12, at the time when the "squeezing operation" is performed up to S2, the suit of "4 pin" is determined to be "4 pin" from the distance of the two visible suits, and the rank of card 110 can be determined to be either 9 or 10.

[0059] Furthermore, the suit of the "3 pins" can be determined to be "3 pins" from the bottom visible suit and the central suit that is partially visible, and the rank of card 110 can be determined to be between 6 and 8.

[0060] Furthermore, regarding the suit of "2 pins," it is possible to determine that it is "2 pins" from one of the suits visible underneath, and determine that the rank of card 110 is either 4 or 5.

[0061] Regarding the "vertical" suit, it is clear from the part of the suit visible in the center that it is "vertical," and it can be determined that the rank of the card 110 is 1, 2, 3, 11, 12, or 13. Furthermore, if no suit is visible, it can be determined that the rank of the card 110 is 1.

[0062] Next, Fig. 13 shows the state of each card 110 when the user performs a narrowing operation to the S3 position using the playing cards 100 according to this embodiment. Note that for cards 110 that are determined to be "4 pin," "3 pin," or "2 pin" at the aforementioned S2 position, the rank will not be determined again even if the narrowing position is advanced to the S3 position. Therefore, Fig. 13 omits the illustration of these cards 110 and shows cards 110 with ranks of 1, 2, 3, 11, 12, and 13 that can be determined to be "vertical" at S2.

[0063] 13, for cards 110 of rank 1 or 2, only one or two suits are displayed vertically on the card 110, and no suits are displayed in the center (near the intersection of the first reference line 140 and the second reference line 150) of the card 110. Also, for a card 110 of rank 3, in addition to the two suits displayed on the card 110 of rank 2, a suit is also displayed in the center (near the intersection of the first reference line 140 and the second reference line 150) of the card 110.

[0064] On the other hand, for cards 110 of rank 11, 12, and 13, a cluster 210 is displayed near the intersection of the first reference line 140 and the second reference line 150, and one second figure 220 representing the suit of the card 110 is displayed on each side of the cluster 210 along the first reference line 140, in the same position and size as for cards of rank 2 and 3.

[0065] Therefore, when the "squeezing operation" is performed from position S2 to S3, for cards 110 ranked 1, 2, and 3, only a portion of the lower suits of the "vertical" suits is visible, and the central and upper suits are not visible. On the other hand, for cards 110 ranked 11, 12, and 13, a portion of the lower suits of the "vertical" suits and a portion of the central group 210 become visible. Note that, since the user performs the squeezing operation while hiding the index with their finger, the index is not visible even when the squeezing operation is performed in an orientation like the diamond 1 card 110 in FIG. 13.

[0066] As described above, although the size of the aggregate 210 is approximately equal to that of the second figure 220, the aggregate 210 is formed by displaying multiple (9, 10, or 11) first figures 211 in a rectangular area (an area of ​​width W21 x height H21, width W22 x height H22, or width W23 x height H23), and a portion of the first figure 211 displayed at the corner of this area becomes visible.

[0067] 13, when a part of the group 210 is not visible at the timing when the "squeezing operation" is performed up to S3, it can be determined that the rank of the cards 110 is one of 1, 2, and 3. When a part of the group 210 is visible, it can be determined that the rank of the cards 110 is one of 11, 12, and 13. In the case of baccarat, cards 110 of ranks 11, 12, and 13 are counted as 0 points, but according to the playing cards 100 of this embodiment, it is possible to prevent the user from knowing that the cards 110 are of ranks 11, 12, and 13 until the user turns over the cards 110 to the S3 position.

[0068] Next, FIG. 14 shows the state of each card 110 when the user performs a squeezing operation to position S4 using the playing cards 100 according to this embodiment.

[0069] As shown in Figure 14, when the "squeezing operation" is performed from position S3 to S4, the suits of the cards 110 with ranks of 1 to 10 look different. Therefore, as shown in Figure 14, when the "squeezing operation" is performed up to S4, the ranks of all cards 110 from 1 to 10 become clear.

[0070] As described above, according to the playing cards 100 of this embodiment, the timing at which the rank of the card 110 is identified can be delayed when the user performs the squeezing operation, allowing the user to enjoy the thrill of the squeezing operation for a longer period of time. Furthermore, with the playing cards 100 of this embodiment, the identification of cards 110 with ranks of 1, 11, 12, and 13 can be delayed compared to ordinary playing cards, so the number of possible ranks that can be predicted from the appearance of the card 110 during the squeezing operation increases compared to ordinary playing cards. This makes it possible to further excite the user performing the squeezing operation.

[0071] The designs of the cards 110 with ranks 11, 12, and 13 are not limited to the examples described above. For example, designs such as those shown in FIG.

[0072] In the case of the cards 110 shown in FIG. 15, the faces of the 11, 12, and 13 cards 110 do not have the images of Jack, Queen, and King, but rather the figures of the 11, 12, and 13 suits, respectively.

[0073] Specifically, in the case of the spade 11 card 110 shown in Figure 15, a collection 210 of first figures 211 representing the suit (spades) of the card, which is equal to 7, obtained by subtracting 4 from the rank of the card 110, 11, is displayed at the position (the center of the card 110) where the first reference line 140, which is parallel to and equidistant from the two long sides 120 (first long side 121 and second long side 122), and the second reference line 150, which is parallel to and equidistant from the two short sides 130 (first short side 131 and second short side 132), intersect, and one second figure 220 representing the suit (spades) of the card 110 is displayed in each of the four areas 160 (161 to 164) separated by the first reference line 140 and the second reference line 150. Specifically, these four second figures 220 are displayed in the same positions as the figures of the four suits displayed on the card 110 with a rank of four.

[0074] Here, the size of the second graphic 220 is the same as the size of the suit graphic displayed on each card 110 whose rank is 1 to 10. The size of the first graphic 211 is determined to be the same as that of the second graphic 220 and smaller than that of the first graphic 211.

[0075] Furthermore, the width W31 (length along the second reference line 150) of the assembly 210 is determined to be approximately equal to the width W1 of the second figure 220. For example, W31 is determined to be the same value as W1 (W31 = W1), or within a predetermined range (for example, within ±5%) of W1. Furthermore, the height H31 (length along the first reference line 140) of the assembly 210 is determined to be approximately equal to the height H1 of the second figure 220. For example, H31 is determined to be the same value as H1 (H21 = H1), or within a predetermined range (for example, within ±5%) of H1.

[0076] Within a rectangular area of ​​width W31 and height H31, two first figures 211 are displayed in a row vertically (along the first reference line 140), three first figures 211 are displayed in a row vertically, and two first figures 211 are displayed in a row vertically (along the second reference line 150) in that order.

[0077] This configuration allows the user to visually recognize a single aggregate 210 made up of multiple first figures 211 as if it were a single figure, making it possible to display the aggregate 210 and the second figure 220 on the surface of the card 110 without creating a sense of incongruity.

[0078] Next, the 12 of spades differs from the 11 of spades in that the cluster 210 is made up of eight first figures 211.

[0079] In the case of the 12 spades, the size of the group 210 is also set to be approximately equal to that of the second figure 220, but since the group 210 of the 12 spades is made up of eight first figures 211, one more than the group 210 of the 11 spades, the size of the group 210 of the 12 spades is larger than the size of the group 210 of the 11 spades.

[0080] Specifically, the width W32 (length along the second reference line 150) of the group 210 in the case of the spade 12 is set to be approximately equal to the width W1 of the second figure 220. For example, W32 is set to be the same value as W1 (W32 = W1) or within a predetermined range (e.g., ±5%) of W1. The height H32 (length along the first reference line 140) of the group 210 is also set to be approximately equal to the height H1 of the second figure 220, but is set to be slightly longer than H31 (e.g., H32 = (4 / 3) × H31).

[0081] Within a rectangular area of ​​width W32 and height H32, two first figures 211 are displayed in a row vertically (along the first reference line 140), four first figures 211 are displayed in a row vertically, and two first figures 211 are displayed in a row vertically (along the second reference line 150) in that order.

[0082] Alternatively, it is also possible to set the height of the rectangular area to H32=H1, and display three first figures 211 arranged in a vertical line, two first figures 211 arranged in a vertical line, and three first figures 211 arranged in a vertical line in this area, all arranged in that order horizontally. In this case, the size of the group 210 of 12 spades can be made equal to the size of the group 210 of 11 spades.

[0083] The 13 of spades differs from the 11 of spades in that the cluster 210 is made up of nine first figures 211.

[0084] In the case of the spades 13, the size of the group 210 is also determined to be approximately equal to that of the second figure 220. The group 210 of spades 13 is made up of nine first figures 211, but the size of the group 210 of spades 13 is the same as that of the group 210 of spades 11.

[0085] Specifically, the width W33 (length along the second reference line 150) of the group 210 in the case of the spade 13 is set to be approximately equal to the width W1 of the second figure 220. For example, W33 is set to be the same value as W1 (W33 = W1) or within a predetermined range (e.g., ±5%) based on W1. The height H33 (length along the first reference line 140) of the group 210 is also set to be approximately equal to the height H1 of the second figure 220 (e.g., H33 = H1).

[0086] Within a rectangular area of ​​width W33 and height H33, a total of nine first figures 211 are aligned and displayed in three rows vertically (along the first reference line 140) and three columns horizontally (along the second reference line 150).

[0087] According to the playing cards 100 of this embodiment, even in this manner, the timing at which the rank of the card 110 is identified can be delayed when the user performs the squeezing operation, allowing the user to enjoy the thrill of the squeezing operation for a longer period of time. Furthermore, with the playing cards 100 of this embodiment, the identification of cards 110 with ranks of 1, 11, 12, and 13 can be delayed compared to ordinary playing cards, so that the number of possible ranks that can be predicted from the appearance of the card 110 during the squeezing operation increases compared to ordinary playing cards. This is expected to further excite the user.

[0088] Furthermore, when the above-described cards 110 are viewed with the two long sides 120 oriented left and right, the index 300 is displayed at a position that is either the upper left side (rear side) or the lower right side (front side). By displaying the index 300 only at the upper left side (rear side) or the lower right side (front side), it is possible to reduce by half the probability that the rank will be unintentionally revealed, even if the user forgets to cover the index with their finger during the squeeze operation.

[0089] Like other cards 110, the card 110 assigned rank 1 has the index 300 displayed only at either the upper left side (rear side) or the lower right side (front side) when the card 110 is viewed with the two long sides 120 aligned horizontally. However, in the case of a card 110 with rank 1, it is preferable to display the index 300 only at the upper left side when the card 110 is viewed with the one short side 130 (first short side 131) closer to the second figure 220 representing the suit of the card 110 aligned downward, as shown in Fig. 17. According to this aspect, for example, if the user starts squeezing the card 110 from the first short side 131 in a "vertical squeezing" motion, the suit becomes visible immediately after squeezing and the user knows that the suit is "vertical." Therefore, the user predicts that the rank is 1, 2, 3, 11, 12, or 13, and becomes excited by the large number of possibilities. At this time, even if the user accidentally forgets to cover the corners of the card 110 with their fingers, the index 300 will not be visible, preventing the user from discovering the card type. Conversely, if the user starts squeezing the card 110 using the "vertical squeeze" method from the second short side 132 opposite the first short side 131, the suit will not be visible immediately after the user starts turning over the card 110, and the user will quickly discover that the rank of the card 110 is 1. Therefore, even if the user forgets to cover the corners of the card 110 with their fingers and the index 300 becomes visible, the impact on the user will be minimal.

[0090] However, the playing cards 100 according to this embodiment may be configured to display the index 300 on both the upper left side (rear side) and the lower right side (front side), similar to common playing cards.

[0091] The back surface of each card 110 described above may be configured to display a back surface pattern 410 as shown in Fig. 17. This back surface pattern 410 displays a guide sign 411 that guides the user in the squeezing operation.

[0092] 17, the guide sign 411 guides the user to turn over the card 110 starting from the short side (first short side 131) on the front side of the card 110 that is farthest from the index 300. This configuration makes it possible to prevent the index 300 from being seen even if the user accidentally forgets to cover the corner of the card 110 with his or her fingers when performing a squeezing operation (especially vertical squeezing).

[0093] Furthermore, by turning over the card 110 from the first short side 131 that is farther from the index 300, in the case of a card 110 of rank 1, the second figure 220 representing the suit of the card 110 begins to appear when the card 110 is turned over to the "S2" position in the diagonal draw described above, or immediately after starting to turn over in the vertical draw, and the user realizes that the card is "vertical." Therefore, the user can predict that the rank is one of 1, 2, 3, 11, 12, or 13, and the large number of possibilities can further increase the user's sense of excitement.

[0094] The guide sign 411 displayed on the back of the card 110 may be text as shown in FIG. 17, or may be a symbol or illustration such as an arrow indicating the direction in which to turn over the card 110, or a combination of these.
