摘要:
Provided is a game device using game tokens with a newly added element not found in conventional game devices. In the present token game device, the token game processing system and the video game processing system are linked. That is, the processing of the video game in the satellite unit (2) is commenced in accordance with whether or not a token hit the target (3). The processing contents of the video game are altered in accordance with the player's operation of the lever (23). Then, tokens are paid out to the player in accordance with the processing results of such video game. Therefore, the player is able to enjoy various operations, and provided is a game in which the player will not lose interest.
