Abstract: A progressive gaming system comprises a plurality of gaming machines, each of which is constructed to perform a predetermined main game in response to an operation of a player and gives a prize to the player when a winning combination is formed in the main game; and a progressive unit for counting an amount of a progressive bonus based on an amount of a bet in the main game played in each of the gaming machines and controlling a payment of the progressive bonus in association with a result of the main game. Each of the gaming machines or the progressive unit is provided with a judging device for judging whether or not the result of the main game played in each of the gaming machines meets a predetermined bonus chance condition for proceeding to a lottery game.

Abstract: An image display game apparatus has a display screen which displays randomly selected five cards with their faces up. Based on the player's evaluation of the cards, the player selectively presses a first group of push buttons to select unwanted cards and indicate replacement of the cards. When the player presses a push button in a second group, the selected unwanted cards are replaced with new cards. If the new combination of the cards achieves a prize-winning hand, then the player wins and is awarded a credit based on odds for the prize-winning hand. The player then pushes another push button in the second group to receive medals corresponding to the credit. The image display game apparatus has an odds display device which displays a present prize-winning hand and odds thereof, a possible prize-winning hand and odds thereof, and other prize-winning hands and odds thereof in respective display modes, e.g., color shades, different from each other.
