Wild symbols substitute any other symbols except fever. Five wild symbols on an active pay-line win the highest odds. Ten or more of the same symbols appearing on the reels at one time may have a chance to trigger all of a kind. The calculation for all of a kind and a common pay line are different. All of a kind multiplies the bet amount by the payout ratio. Fever appears on reels one, three and five. Three fever symbols trigger the fever game.
