Description

[Technical field]

[0001] The present invention relates to a game system, and more particularly to a game system capable of determining the timing of use. [Background technology]

[0002] As shown in Figure 1, a slot machine 1 is a type of extremely popular game machine. The slot machine 1 has multiple slots 2, and after a player withdraws money, he or she spins the multiple slots 2 and can earn points according to the symbol arrangement formed when the multiple slots 2 stop. The method is simple, and various game rules and methods can be set according to the player's requests and preferences, so that the preferences of each individual player can be met.

[0003] According to conventional game rules, when a specific symbol appears or a preset condition is met, a bonus game with a predetermined number of rounds is started. The bonus game is characterized by a free spin, in which the player can get additional bonus points without adding money. This is one of the main reasons that slot machines attract players.

[0004] Another common form of bonus game is to respin the slots, as shown in the process of Figure 4 of US Patent No. 5,233,633, and US Patent No. 5,233,633 discloses scoring mystery symbols based on collected configurable symbols.

[0005] However, in the conventional gaming system, when a certain symbol is obtained or the collected symbols meet a preset condition, the bonus is immediately given and the player cannot choose the timing of using the bonus, so that the player is likely to quit the game after obtaining the bonus, which will cause the game play to be discontinued and the player will not want to continue using the gaming system.

[0021] The technical contents of the present invention will be described in detail below with reference to the drawings. 2, 3, 5A and 5B, which is a first embodiment of the present invention, a game system 10 capable of determining a timing of use is disclosed in this embodiment of the present invention, the game system 10 is installed in a game machine 20, the game system 10 provides a slot game by the game machine 20, and the slot game provides at least one game round for the player to play based on the player's operation. The game system 10 includes a display unit 11, a game result generating unit 12, a storage unit 13 and a control unit 14, the display unit 11 includes a game screen 30, the game screen 30 displays a real-time game image of the at least one game round, and the game screen 30 includes a plurality of display positions 31 arranged in a matrix.

[0022] The slot game generates a plurality of game symbols 40 in the at least one game round by the game result generating unit 12, and a game result is determined when the plurality of game symbols 40 are displayed at the plurality of display positions 31 on the game screen 30, and the plurality of game symbols 40 include any of a plurality of items 50 with a certain probability (see FIG. 5B), and each of the plurality of items 50 has a predetermined game effect. The storage unit 13 is used to record any of the items 50 generated in the at least one game round. The items 50 may also be acquired in other ways. In one possible embodiment, when the control unit 14 determines that the player has achieved a predetermined rule in the slot game, the player can acquire at least one of the plurality of items 50, and records it in the storage unit 13, and the predetermined rule is that the plurality of game symbols 40 form a specific arrangement, or that an event rule is satisfied, or that the item is a promotional item, etc.

[0023] In implementation, the game result generating unit 12 may be a plurality of slot units 121, and the plurality of slot units 121 generate a plurality of game symbols 40 in a manner of rotating and stopping. In one possible embodiment, the number of the plurality of slot units 121 corresponds to the number of the plurality of display positions 31, that is, each display position 31 is provided with one slot unit 121, and each slot unit 121 independently generates one game symbol 40. In another possible embodiment, the plurality of game symbols 40 displayed at the plurality of display positions 31 in the same column are generated by the same slot unit 121. That is, the plurality of game symbols 40 in the same column are displayed to rotate continuously from top to bottom. For example, when the game screen 30 includes a plurality of display positions 31 arranged in a 3×5 matrix and displays a plurality of game symbols 40, the embodiment is implemented with five slot units 121, that is, each slot unit 121 simultaneously displays three rows of a plurality of game symbols 40 on the game screen 30. Upon spinning, a number of game symbols 40 move from the first row to the second row, and finally to the third row, and then disappear from the game screen 30.

[0024] 3 and 4, the control unit 14 is connected to the display unit 11, the game result generating unit 12 and the storage unit 13, and when sequentially playing the at least one game round, the control unit 14 performs the following steps:

[0025] First, step S1 is carried out to determine whether or not an item is to be used. In other words, it is determined whether or not the player in question is to use the item 50 written in the storage unit 13. If the player uses at least one item 50 stored in the storage unit 13, step S2 of using the item is performed, and if the player does not use the item 50, step S3 of playing the normal game is performed.

[0026] In the step S2 of using the item, the control unit 14 further performs the following steps: Step S2-1 involves deleting an item, i.e. deleting an item 50 from storage unit 13 that has already been used. In step S2-2, an item effect is generated, that is, a plurality of game symbols 40 are generated by the game result generating unit 12 while generating the corresponding predetermined game effect. Step S2-3: End the game round, i.e., pay out and end the game round. Also, according to the game design, the items 50 may have various functions and uses, for example, the items 50 may generate the corresponding predetermined game effect when used alone, or the items 50 may be fragments, where multiple related items 50 are a group, and multiple predetermined items 50 need to be used in combination to generate the corresponding predetermined game effect, or the items 50 may be used alone or in combination, and the effect can be increased when multiple items 50 are used in combination to generate the predetermined game effect with different strength.

[0027] In step S3 of playing the normal game, the control unit 14 further performs the following steps. In step S3-1, it is determined whether to generate game symbols, i.e., whether a plurality of game symbols 40 are generated by the game result generating unit 12, and if not, the game round is ended, and if so, the next step is continued. In step S3-2, game symbols are generated, ie a plurality of game symbols 40 are generated by the game outcome generating unit 12. In step S3-3, it is determined whether an item has appeared, i.e., whether any of the newly generated plurality of game symbols 40 contains the item 50, and if so, step S3-4 is performed to record the item, i.e., the generated item 50 is written by the memory unit 13. In step S3-5, the game round is ended, that is, the payout is made and the game round is ended.

[0028] 3 and 5A to 5D, in a first embodiment of the present invention, first, as shown in FIG. 5A, when playing at least one game round, the game result generating unit 12 generates a plurality of game symbols 40 by a plurality of slot units 121 in a manner of spinning and then stopping.

[0029] Next, as shown in FIG. 5B, when playing the at least one game round, the multiple game symbols 40 include any one of the multiple items 50 with a certain probability, and the designs of the multiple items 50 are determined based on a game design, and the multiple items 50 having different game effects may each have a different design.

[0030] There is no particular limitation on the manner in which the items 50 appear. For example, as shown in FIG. 5B, the items 50 may be a single design that is movably attached to any of the game symbols 40. Alternatively, the items 50 may be combined with the game symbols 40, that is, the items 50 appear together with the same game symbol 40 by the slot unit 121.

[0031] Then, as shown in FIG. 5C, when the items 50 appear, the player may increase the size of the items 50 so that the type of items 50 that the player has collected can be clearly seen.

[0032] Next, as shown in FIG. 5D, when any of the items 50 are collected, they may be recorded using the memory unit 13, and to indicate that the memory unit 13 has already recorded the item 50, the item 50 may be moved on the game screen 30 to the function operation area 32 of the game screen 30, thereby indicating that the item 50 has already been stored in the memory unit 13.

[0033] The player may also have a member account, the member account including account materials, the account materials may include items 50. The items 50 included in the account materials may be transferred to the storage unit 13, and the items 50 included in the storage unit 13 may be transferred to the account materials. The control unit 14 transfers the items 50 included in the account materials to the storage unit 13 before the start of the first round of the at least one game round, and the control unit 14 transfers the items 50 recorded in the storage unit 13 to the account materials after the end of the final round of the at least one game round, and the items 50 may be divided into several parts and collected by the player, which may encourage the player to play in fragmented time.

[0034] In another possible embodiment, the control unit 14 transfers the items 50 listed in the account materials to the storage unit 13 at the start of each game round, and the control unit 14 transfers the items 50 recorded in the storage unit 13 to the account materials at the end of each game round, i.e., transferring the items 50 at both the start and end of each game round, thereby avoiding the risk of losing the items 50 recorded in the storage unit 13.

[0035] 2 and 6, which is a second embodiment of the present invention, in which the game system 10 also includes a display unit 11, a game result generating unit 12, a storage unit 13, and a control unit 14, and further includes a member management unit 15, where the member management unit 15 is used by the player to create the member account, the member account also includes the player's account information and further includes a consumption record, and the member management unit 15 can select at least one of the items 50 based on the consumption record and the granting rule, write the item 50 written in the account information to the storage unit 13, and can also transfer the item 50 written in the storage unit 13 to the account information. In addition, the functions and operation manner of the items 50, the display unit 11, the game result generating unit 12, and the storage unit 13 may refer to the contents described in the first embodiment. In addition, one possible embodiment of the granting rule is to give a proportional number of the items based on the consumption record, that is, the larger the consumption record, the more the items to be given.

[0036] 6 and 7, in the second embodiment, the control unit 14 is connected to the member management unit 15, the display unit 11, the game result generating unit 12 and the storage unit 13. And, when playing the at least one game round in sequence, the control unit 14 performs the following steps in each game round: First, step P1 of importing items is performed, i.e., the items 50 described in the account materials are transferred to the storage unit 13; then step P2 of determining whether to use items is performed, i.e., it is determined whether the player will use the items 50 described in the storage unit 13; if the player uses at least one item 50 described in the storage unit 13, step P3 of using items is performed; if the player does not use any item 50, step P4 of playing a normal game is performed; after the game round is completed, step P5 of exporting items is performed, i.e., the items 50 described in the storage unit 13 are transferred to the account materials.

[0037] Step P3 of using an item is the same as step S2 of using an item, and the contents of the first embodiment may be referred to.

[0038] In step P4 of playing the normal game, the control unit 14 further performs the following steps. In step P4-1, it is determined whether to generate game symbols, i.e., whether a plurality of game symbols 40 are generated by the game result generating unit 12, and if not, the game round is ended, and if so, the next step is continued. In step P4-2, game symbols are generated, ie, a plurality of game symbols 40 are generated by the game result generating unit 12. In step P4-3, the game round is ended, that is, the payout is made and the game round is ended.

[0039] 6 and 8, this is the third embodiment of the present invention, which differs from the second embodiment in that the timing of transferring the item 50 described in the account materials to the memory unit 13 and the timing of transferring the item described in the memory unit 13 to the account materials are different. More specifically, the control unit 14 transfers the item 50 described in the account materials to the memory unit 13 before the first round of the at least one game round begins, and the control unit 14 transfers the item described in the memory unit 13 to the account materials after the final round of the at least one game round ends.

[0040] Therefore, in the third embodiment, when the at least one game round is played in sequence, the control unit 14 performs the following steps in each game round: perform step T1 of determining whether to use an item, i.e., determine whether the player uses an item 50 stored in the storage unit 13, perform step T2 of using an item if the player uses at least one item 50 stored in the storage unit 13, and perform step T3 of playing the normal game if the player does not use an item 50.

[0041] In addition, in the third embodiment, step T2 of using an item and step T3 of playing the normal game are the same as step P3 of using an item and step P4 of playing the normal game in the second embodiment, respectively, and the contents of the second embodiment may be referred to.

[0042] As can be seen from the above, the present invention has at least the following advantages: 1. Items with different predetermined game effects can be collected, and players can freely choose the timing to use them according to their needs, which prevents the game from being discontinued and forces players to wait until the best timing to use them, thereby achieving the effect of continuing to use the game system and effectively increasing the revenue of the game system.

[0043] 2. Players can experience more variety in the way they collect items, which will attract players and prevent them from losing interest.

[0044] 3. The collected items can be stored in the member account, which encourages players to play in their spare time, effectively improving the utilization rate of the game console. [Explanation of symbols]
