It is determined whether the number of acquired tokens reaches the upper limit when a token is acquired. When the number of acquired tokens reaches the upper limit, a two-dimensional code display recommendation notice is executed. When a player acquires a two-dimensional code and accesses a management server to store the number of acquired tokens, the acquired tokens are further prevented from being invalidated in acquisition of the token.SELECTED DRAWING: Figure 33 |
