Santa’s Stack Slot

So, what should players expect from this seemingly joyful endeavour? Read on below to find out!

Santa’s Stack Features

Rather than assail players with a never-ending list of functions and features, Relax Gaming has opted for a more minimal and focused approach. The slot makes use of cluster pays that also trigger a cascade feature whenever a win is made. Additionally, players can activate both a re-spins and free spins feature through gameplay mechanics or the monetized buy feature.


Santa’s Stack triggers a re-spin feature whenever a wild symbol forms part of a winning combination. The winning cluster is transformed into mystery symbols and locked onto the reels, while the rest of the symbols spin again. If a win lands adjacent to the mystery symbols, then the new winning cluster is also turned into mystery symbols. All mystery symbols are locked in and the remaining symbols spin once more. When there are no more subsequent wins, the mystery symbols all reveal an identical symbol, ending the feature.

Buy Feature

3 Scatters are the key to entering the game’s free spins through conventional means, but players who want to jump straight into the action can opt for the Buy feature. Here players can pay 100x their current bet for direct access to free spins and an RTP increase to 97%.

Santa’s Stack Free Spins and Bonus

The main event in Santa’s Stack, free spins are activated through the landing of scatter symbols or the buy feature. Players get 5 free spins with more spins added on for each additional scatter symbol. In free spins, wild symbols are guaranteed to land on every spin, increasing the chances of triggering the re-spins feature. The wild symbol count also increases by 1 one on every spin. Any new scatters that land can add a new spin to the tally, increase the win multiplier by 1, or both.

Luckily the slot’s RTP is just a bit more forgiving at a 96.27% rate and that can be taken up to 97% when activating the bonus buy feature.
