Slot machine and playing method thereof

Abstract

A part of credits paid by the player is accumulated when a plurality of symbols are displayed by a scrolling display and then rearranged in a prescribed combination, and a stop switch is set active only in a case where a predetermined combination is determined. When a plurality of symbols are rearranged in a combination of jackpot symbols in relation to a timing of an input by a player, a payout of the accumulated credits is made. Consequently, the reels can be stopped by an operation of the player himself, and in a case where a combination of the stopped symbols is a combination associated with a payout, a payout can be received as a reward, so that the player's interest to the game can be increased.
