King Crab has a five reel, nine line monitor display that is based on the server-based bingo card results. The player may wager 9 to 45 credits per game, resulting in a maximum payout of 125,000 credits. The pay lines are used to show the outcome of the player's bingo card. Winning combinations display on one or more pay lines, where the amount won is multiplied by the number of coins wagered on that line.
The King Crab display has a Caribbean theme. It utilizes underwater characters such as shells, fish and coral as reel symbols and calypso sounds for winning pays.
Scatter pays are an entertaining way to display the bingo outcome. When three or more oysters appear in any position on the screen, the player is presented with a second screen of 5 oysters. The player selects an oyster; it opens and exhibits the winning amount for the current wager based on the initial bingo pattern win.
