For each round of WinSpins, players are guaranteed a credit prize. This can go anywhere from 1 to 500 credits.

Players can win credit prizes through WinSpins and Bonus Games. This is played on another reel or screen. For this round, the prizes are bet multipliers. The biggest jackpot in this game is a 2,000x multiplier.
