Abstract: A game machine (10) includes a card interface (11) configured so that a magnetic card (20) is detachably attached thereto, an element (12) to record a card ID generated on the basis of time information specifying the date and time when the magnetic card (20) is attached to the card interface (11) in a magnetic data recording area (22) provided in the magnetic card (20), and an element (14) to print an access code uniquely obtained by the calculation of a predetermined function based on the card ID in a printing area (21) of the magnetic card (20).

Abstract: A game apparatus is provided with: determination unit for determining, in a stage of a game, whether or not a kind and order of deal to players of game media are fixed; storage unit for storing restoration data required to restore a game status at time points in a storage medium for each of check points, wherein at least a first timing indicating a time point when a virtual game value possessed by player increases/decreases as a result of the game by betting operations and a second timing indicating a time point when the kind and order of deal are fixed are used as check points; and restoration unit for reading out the restoration data from the storage medium upon restoring a fault including power disconnection during execution of the game, and automatically restoring the game status at the latest check point based on the restoration data.

Abstract: An object of the present invention is to provide a game machine having high data management ability. In order to achieve this object, the game machine (10) of the present invention includes a card interface (11) configured so that a magnetic card (20) is detachably attached thereto, card ID recording means (12) for recording a card ID generated on the basis of time information specifying the date and time when the magnetic card (20) is attached to the card interface (11) in a magnetic data recording area (22) provided in the magnetic card (20), and printing means (14) for printing an access code uniquely obtained by the calculation of a predetermined function based on the card ID in a printing area (21) of the magnetic card (20).
