Winnings take the form of additional balls, which players may either use to keep playing or exchange for prizes (景品 "keihin"). When players wish to exchange their winnings, they must call a parlor staff member by using a call button located at the top of their station. The staff member will then carry the player's balls to an automated counter to see how many balls they have. After recording the number of balls the player won and the number of the machine they used, the staff member will then give the player a voucher or card with the number of balls stored in it. The player then hands it in at the parlor's exchange center to get their prizes. Among the array of prizes available, there will invariably be an item known as the "special prize" (特殊景品 "tokushu keihin": typically a small silver or gold novelty item encased in plastic) that can be sold for cash at an outside establishment in the vicinity of the parlor. Special prizes are awarded to the player in amounts corresponding to the number of balls won. For example, one special prize worth ¥1500 outside the parlor might be offered to a customer per 400 balls won, assuming each ball originally cost 4 yen. The vast majority of players opt for the maximum number of special prizes offered for their ball total, selecting other prizes only when they have a remaining total too small to receive a special prize.
