Title: Game machine
Inventor: KATO MASACHIKA
IPC: A63F7/02
Filed: 2020-05-07
Abstract: To provide an information medium and a game machine capable of granting a new additional value allowing a player to maintain interest in a game for a long time.SOLUTION: In a game machine, leakage prevention means prevents contents of a special value that a special value medium stored in storage means has from being leaked. Thus, since leakage of the contents of the special value before the special value medium is granted from the storage means is prevented, a player grasps the contents of a special value before acquisition of the special value medium, thus preventing a sense of expectation toward the acquisition from being lost. Thus, the player's sense of expectation toward acquisition of the special value medium can be always maintained, and the player can maintain interest in a game for a longer time.SELECTED DRAWING: Figure 88
