With the cluster pays mechanic, the Santa's Stack slot's action takes place on an 8 by 8 grid. Landing clusters of at least 5 matching symbols up to a maximum of 60 symbols results in winning combos.
With stakes ranging from 0.10 to 50, this slot is suitable for players with all types of bankrolls. Simply use the - or + on either side of the bet total below the reels to alter the bet size.
The lower value symbols on the reels are blue, green, and red lights. The higher value symbols are Santa Claus, Mrs. Claus, elves, reindeer, and sleighs. The most lucrative symbol is Santa Claus, who may pay up to 10,000 times your stake for filling 60 positions. For a cluster of at least five symbols, it pays 1x your bet.
When a wild symbol becomes a constituent of a lucrative cluster, the Secret Santa feature is activated. As a respin is given, the winning cluster will then change into mysterious symbols. Until the mystery symbols are disclosed, each sign in the cluster will be wrapped as a Christmas present. The reels' mysterious symbols remain in place.
To activate this feature, land three or more bonus Christmas tree symbols anywhere on the reels. You will see a bonus space to the right of the reels with 3 stars. Filling these stars with three Christmas trees will start the feature.
The first five free spins you receive are yours to keep, and each additional bonus symbol awards you a further free spin.
It's important to note that the Secret Santa feature is still active during the free spins and that you will undoubtedly activate it at the beginning of each one. The guarantee of a wild grows by one per free spin, starting with 1 wild on your very first free spin.
