AI Technical Summary

Benefits of technology

[0012]A game card according to the present invention may be used for a card game for two or more players that comprises a deck of cards with a plurality of visually recognizable informational indications disposed on a front face thereof, and a play field where at least one of the cards is placed in the course of the game. Here, a reader is used which optically, magnetically, or electronically recognizes the identifying indications and displays a recognition result in the form to be visually and / or audibly recognized. The reader is configured to selectively read one of the identifying indications by a single reading operation. When a plurality of identifying indications are displayed on the card, at least one identifying indication can be selected from the plurality of identifying indications by using the reader. Consequently, the result may be varied according to how to select identifying indications, thereby allowing unexpected developments in the game. Preferably, when the reader is operated for a reading operation in the course of the game and selectively reads at least one of the identifying indications, the reader may display the recognition result based on the at least one identifying indication which has been read. More preferably, the reader may be configured to output the recognition result which varies according to a combination of the identifying indications which are read or an order in which the identifying indications are read. With this configuration, an unexpected result may be obtained based on the combination of the identifying indications, thereby allowing the player to always enjoy new and fresh developments even if the player is accustomed to the game.

[0013]In the game card of the present invention, since positions at which a plurality of identifying indications are disposed are defined in relation to positions at which a plurality of visually recognizable informational indications are disposed, the player searches for the identifying indications by using the reader, conjecturing where the plurality of invisible identifying indications are disposed with reference to positions at which the plurality of the visible and visually recognizable informational indications are disposed. Thus, the player cannot immediately determine what result can be obtained by selecting identifying indications, although the card belongs to the player. Accordingly, the game can develop in an unexpected way and the player can enjoy a thrilling game. Additionally, since a plurality of invisible identifying indications are provided on the card, the player cannot predict what identifying indications the opponent player will select even if it is known that a plurality of identifying indications are hidden in the card. Thus, the player can enjoy a thrilling game.

Problems solved by technology

Therefore, nobody can know the contents of the identifying information unless he or she reads the data stored on the card by a dedicated reader.
