About this Slot

The Wild symbol substitutes for regular symbols to complete winning combinations. Three or more Scatter symbols trigger the Free Spins feature, during which escalating multipliers apply to wins.
The Ladder Bonus mini-game activates during Free Spins, increasing prize values with each step climbed. The Multiplier Ladder rises with each win during the feature, building larger payouts as the round progresses.
Free Spins can retrigger when additional Scatters land, extending the bonus round and continuing the multiplier climb.
A Gamble Feature is available after wins, offering the chance to double or quadruple the payout by predicting either the colour or the suit of a face-down card.
