Slot Features

Santa's Stack is as rare as an original Christmas slot, and it is powered by an 8x8 cluster payout engine. A winning cluster containing a wild symbol activates Secret Santa Respins with accumulating mystery symbol clusters, which are eventually disclosed. You can earn up to 20,000 times your bet during the bonus round, which features a growing number of guaranteed wilds per spin.

Santa's Stack contains few features, yet they are quick and capable of inciting excitement when they perform. These are the Secret Santa Respin and free spins features.

This function is activated whenever a winning cluster contains a wild symbol. The winning cluster transforms into mysterious symbols and becomes immobile for the next spin. If a win occurs adjacent to locked mystery symbols during a respin, the new winning cluster is converted to mystery symbols and another respin is rewarded. When there are no fresh winning clusters near to mystery symbols, they all convert into the same symbol kind.

When at least three scatter symbols appear, five free spins are awarded, plus one extra free spin for each additional scatter symbol visible. During free spins, wild symbols are guaranteed to appear at the beginning of each spin, aiding in the activation of the Secret Santa Respin bonus. The amount of guaranteed wilds increases by one with each spin, beginning with one on the opening free spin. When scatter symbols appear during the feature, players receive either an additional free spin or a one-time win multiplier boost, or both.
