You can stop the autoplay by clicking on the spin button, which turns red when this function is active.


The Wild Joker Stacks slot’s RTP ranges from 95.60% to 97.35%. This depends on the row level and the multiplier you use during your gameplay. The more rows and jokers you add, the higher the RTP!
