'Twas the night before Christmas, and no slots were spinning. Fingers were still and silence was far and wide. Out of the darkness came a distant cry, “Santa’s Stack is a game we must try! Now, Rudolf, Dasher, Dancer, Prancer and Vixen, on, Comet, on, Cupid, on, Donner and Blitzen! Tonight, the presents can wait a minute; 20,000x we can win, and we’re all in it!” Join the Christmas clan in this festive delight where festivity is on an 8x8 grid, nestled against a retro-style winter wonderland. For fans of the cluster mechanic, this is the gift that keeps giving! Create wins through clusters of five or more matching symbols, with wilds, respins, and the Secret Santa Feature set to help you along. Landing 3 or more Christmas Trees awards the Free Spins feature and 5 Free Spins. The more trees, the more spins - with a max. of 8! With the Secret Santa Feature permanently in action from the initial spin and increasing in size after each one, the chances of being showered in gifts escalates. Players can relive the excitement of Christmas Day as many times as they wish through the Feature Buy option, which is also handy for anyone who’s a little impatient unwrapping gift.
