A game apparatus accepts a bet by a player on a betting target from among multiple betting targets. For each target, odds indicating a winning allotment in a first game are set. A drawing is conducted for the first game. According to the result of the drawing, a game medium is paid out. A stake is calculated for a second game whose payout ratio is 1, taking into account, along with a number of bet game media, a difference between a position payout ratio, which serves as a winning allotment expectation value per unit of game media, for the betting target bet on by the player, and a set payout ratio. |
