To provide a Pachinko game machine precisely communicating to a game player that decorative patterns make a jackpot combination in an image of the next decorative-pattern game before the display of the image of the next decorative-pattern game is started.

A game ball is limited to get prize winning into a special pattern starting port at a time interval of "4 ms1250". Time needed until a jackpot counter MR1 is updated to either of jackpot values "301" to "3301" after being updated to minor winning values "(251)" to "(3250)", is set at a value same as the time interval in which the game ball can enter the port. Thereby, when the jackpot counter MR1 of a holding number 2 exists at the time of making a determination of a minor winning, a high possibility of a jackpot is achieved on the basis of the jackpot counter MR1 of the number 2. In the case, in the decorative-pattern game, pattern components in a middle row are stop-displayed and at the same time an image of a previous-announcement performance is displayed, communicating to the player that the decorative patterns make the jackpot combination in the next game.
