The wild helps increase your chances to win by substituting for all regular symbols on the Santa’s Stack online slot. 

Secret Santa Re-spin Feature

This is triggered when a wild forms part of a winning combination. The cluster turns into mystery symbols (which look like presents) and lock into place while the reels grant you a re-spin. This is repeated each time a winning cluster forms beside the mystery symbols. These continue until there are no more wins or wilds forming part of winning combinations. The presents will then reveal the same mystery symbol for one last win.

Free Spins

Collect three bonus symbols while spinning the Santa’s Stack online slot to receive five free spins. You’ll be rewarded with one extra spin for each additional bonus symbol landed. The Secret Santa Re-Spin feature is active throughout this round as wilds are guaranteed to land during each of your free spins.

Any bonus symbols that fall during this round will reward you with a multiplier, an additional free spin, or both.
