Santa's Stack Online Slot Bonus Features
Santa’s Slack is much more than just a charming game design. The title also comes with a selection of fun bonus features that can give players a boost. The first feature is the Secret Santa Bonus.
This is triggered whenever a Wild symbol is part of a winning combination. When this happens, all of the symbols in the combination will turn into presents. This will then trigger a Re-spin, and these symbols will stick. If a winning combination occurs next to this, then this will also transform and become Sticky. Once this happens without a winning combination, then the Re-spins will end, and the Mystery symbols will reveal a Matching symbol.
The other main bonus here is the Free Spins Round. This is triggered when you land three or more Bonus symbols. Three will reward you with five free spins, and you will then get an extra spin for every other bonus that lands in view.
During the round, a Wild is added to the start of each spin in order to help boost the chance of landing the Secret Santa bonus. There is also the chance to add more boosters to this round. Every Scatter you land will give you either an extra Free Spin, a Multiplier, or both. There is also the option of buying your way into the Bonus Round for an increased cost.
