Santa's Stack Features

There's a huge variety of Christmas presents on offer in this slot and it all begins with the Secret Santa Re-Spin feature which is triggered when a wild is part of a winning cluster. This converts the winning symbols into mystery symbols and a respin will be awarded holding the mystery symbols in place. This ends when there are no more winning clusters.

If you land 3 or more bonus symbols on the reels, then you'll trigger 5 free spins and an additional spin per bonus symbol. During this mode, the Secret Santa feature is active and wilds are guaranteed to land on each spin. You'll also find that landing bonus symbols throughout free spins can add additional spins, multipliers or both.

Santa's Stack Review

It's the most wonderful time of the year and Santa is back! This time he is cooler than ever with a whole crew behind him. Developed by Relax Gaming, Santa's Stack is a Christmas slot that plays on a grid of 8x8 using the Cluster Pays mechanic.

With Santa's Stack, you can expect free spins and a respin mechanic that can lead to amazing wins of up to 20,000x your stake. If you want to celebrate Christmas in style, then look no further than Santa's Stack.


It's clear that the designers took inspiration from 8-bit videogames and specifically games like Habbo Hotel with the backgrounds matching the characters. In the base game, you are centred in Santa's grotto with various houses decorated with Christmas lights and there is snow falling onto the ground.

However, this changes throughout free spins as you are transported to the skies with Santa's sled which takes you inside his grotto. You can find the workshop of the elves with an adorable sleeping penguin in the top right corner. This paired with a roaring fire makes it incredibly cosy and inviting.

All the symbols on the reels are either characters relating to Christmas (Santa, Elves, Mrs Claus, Reindeer) or Christmas lights. Thankfully, when you land wins with these characters, they have a little animation which makes it even more exciting.

As for the music, it's an 8-bit track that softly plays throughout the base game but really intensifies through free spins. It manages to sound full of holiday spirit and thrilling to make the feature even more engaging.


Santa's Stack is a delight to play with simple gameplay that's entertaining. It uses the Cluster Pays mechanic which matches up symbols instead of paylines but looks visually delightful. There are only two main features throughout this slot which include free spins and respins meaning it's easy to pick up.

All of the menus are at the bottom of the screen in true Relax Gaming fashion. The spin button is in the middle of the screen whilst the bet level is just to the left of the screen. Further to the left, you'll find an additional menu that'll lead to the paytable and other settings.

Win Potential

This is definitely a slot for players who prefer big wins, but less frequently due to the high volatility. As for the RTP, it's a solid 96.27% which is over the average standard of 96%.

With Santa's Stack, you can expect to win up to 20,000x your stake through the free spins round with multipliers. Whilst, we managed to trigger the free spin feature a fair amount, gaining multipliers can be quite tricky which is something to keep in mind.

Our Verdict

Christmas slots are a strange bunch that either truly delightful or fall flat - but Santa's Stack thankfully falls into the first character. The graphics are charming and the added sound effects and animations deliver something spectacular.

Cluster Pays paired with respins and free spins makes for something magical. If you love high volatility slots and want something more festive, then give Santa's Stack a spin. This is one Christmas slot that you definitely don't want to miss out on.
