Santa’s Stack Review

Coming from Relax Gaming just in time for the merry season, Santa’s Stack is a retro-looking 8×8 grid slot with a Cluster Pays mechanic. The theme and visuals are very festive, but they also reminded us of the old pixelated video games, like Pac-Man, from the late 70s and early 80s. Just like the simple but cosy design, the rules of this game are also easy going, with winning clusters made of 5 more symbols. Santa, awarding 1,000x your stake for a set or 60+, is the highest paying symbol. He’s followed by Mrs Claus, an elf and a red-nose reindeer. The multi-coloured fairy lights appear as low-paying symbols and award 125x, 100x and 75x your stake for a cluster of 60+ red, green and blue lights, respectively.

Santa’s Stack Bonus Features

Santa’s Stack is a fun little game with two jolly bonus features, a mystery respin feature and the free spins bonus round. Both are quite straightforward and also overlap for some cheerful and rewarding gameplay. There’s also a Buy Bonus option available to non-UK players, who can use it to get instant access to the free spins bonus round at the cost of 100x their original bet. Let’s inspect all slot features in detail.


Wilds in Santa’s Stack can activate the Secret Santa respin feature if they’re included in a winning cluster.


Appearing as Christmas trees anywhere on the reels, 3 or more festive scatters can launch the free spins bonus round.

Secret Santa Respins Feature

When a wild is part of a winning combination, it will convert an entire winning cluster into sticky mystery symbols and award a respin. If a new winning cluster appears adjacent to the previously-formed sticky mystery cluster, the new cluster will also turn into a bunch of mystery symbols for another respin. When no more winning clusters appear in view, the feature will end and all the mystery symbols will reveal the same symbol of a kind.

Free Spins

Upon triggering free spins with 3 festive scatters, you’ll have 5 free spins to make the most of this bonus round. The good thing is the Secret Santa feature remains active and this time guarantees wilds on every spin. You’ll start with one guaranteed wild on the first spin, and the number of wilds will increase by one on every subsequent spin. Also, during this feature, every Christmas tree scatter landed can award either an extra free spin, a +1 multiplier or both. By the way, if you trigger the free spins round with more than 3 scatters, you’ll receive +1 free spin on top of your initial 5 free spins for every extra bonus symbol landed.

Santa’s Stack Jackpot

Santa’s Stack is not a jackpot slot, but it could certainly reward you like one. The max you can win during the free spins round is a rocking 20,000x your stake.

RTP and Volatility

For a seasonal slot, the key stats are looking very healthy. The game pulls off a high volatility rate, paired with an above-average RTP of 96.27% or 97% if you’re using the buy bonus feature.
