Santa’s Stack slot design

Clearly, Santa’s Stack Slot has a Christmas theme but Relax Gaming made it more unique by using a retro style. Just imagine the kind of graphics that you see in the classic games you play on old computers and vintage game consoles. They even paired Santa’s Stack with vintage chip music so you can feel its retro vibes while spinning the reels.

Santa´s Stack Slot Comes From Relax Gaming

The game shows a backdrop that is set in a snow-covered town square that is designed with a 3D style. Of course, the whole town is decorated with multi-colored Christmas lights that illuminate the streets. Even the frame of the grid is also decorated with garlands and Christmas lights. In case you are wondering, the bonus round takes place in Santa’s workshop with Santa’s splash of cash while riding his sleigh.

Inside the grid are its paying symbols that show Santa with his friends and Christmas decorations. Its lower-paying symbols consist of light bulbs with different colors such as blue, green, and red. For its premium symbols, Santa’s Stack features Rudolf the Reindeer, an Elf, Mrs. Claus, and Santa Claus himself. Its special symbols include the capital W logo as the Wild symbol, the Christmas Tree Bonus symbol, and the Gift Box Mystery symbol.

Santa’s Stack features

Santa’s Stack doesn’t have surprising features in its grid with 8 reels and 8 rows. Regardless, Relax Gaming made sure they are exciting enough to keep your adrenaline rushing once you start spinning the reels. Aside from its 3 special symbols, there’s also the Secret Santa Re-Spin, Bonus Spins, and the Bonus Buy feature to check out.

Wild Symbol

The game’s Wild is featured as the red capital “W” on a yellow background. This special symbol can help you create more winning clusters throughout the game by replacing all types of regular symbols on the grid. Similar to most Wild symbols, it can’t replace the Scatter as well as the Mystery symbols that are also designed as special symbols. This Wild symbol can also pop and help you trigger the major features in the gameplay to make the game more fun.

Scatter Symbol

Next to the Wild symbol is the Scatter or Bonus symbol that is featured as the Christmas Tree. This Bonus symbol plays a significant role on the grid to trigger the bonus round and land more winning clusters. You can even activate other extra features within the bonus round so keep an eye on this Bonus symbol.

Mystery Symbol

The last special symbol to watch out for in Santa’s Stack is the Mystery symbol. This Mystery symbol is featured as the Gift Box icon that is ready to be delivered by Santa. Similar to the 2 previous special symbols, the Mystery symbol also plays a significant role on the reels to trigger another major feature. If the Bonus symbol is the key to the Bonus Spins, the Mystery symbol is the key to the Re-Spins.

Secret Santa Re-Spin

As mentioned above, the Wild symbol is a key symbol and that is because it can unlock the Secret Santa Re-Spin feature. This is possible each time the Wild symbol lands on the reels and becomes a part of a winning combination. This means that the chance of enjoying this feature often is higher as long as a Wild symbol lands to help you win. Once triggered, the winning cluster that includes the Wild transforms into Mystery symbols that remain locked on the reels and reward the Re-Spins.

If another win is formed adjacent to the locked Mystery symbols during the Re-Spins, all winning symbols will also turn into Mystery symbols. This means that you will be rewarded with Re-Spins again so retrigger is possible in Santa’s Stack Slot. But once no new winning combination is formed adjacent to the Mystery symbols, all Mystery symbols will reveal the same type of symbol. At the same time, a winless spin will automatically end the Secret Santa Re-Spin feature.

Bonus Spins

If you can’t get enough of the Re-Spins, don’t fret because Santa’s Stack still has some Bonus Spins to keep your Christmas merry. This bonus round with 5 initial Bonus Spins can be triggered by landing the first 3 Christmas Tree Scatter symbols. This bonus feature also rewards 1 additional Bonus Spin for each extra Scatter you land. Another benefit of activating the Bonus Spins round is that it can trigger the Secret Santa Re-Spin as well.

This guarantees you to land a Wild symbol on each spin you make. For instance, a Wild symbol will land on your first Bonus Spin together with a Win Multiplier that starts at 1x. This Multiplier increases by 1 each time another Wild symbol lands on each spin. But if you land a Scatter symbol, Santa’s Stack will reward you one of these prizes:

  • Christmas Tree with a blue frame = 1 additional Bonus Spin
  • Christmas Tree with a red frame = 1x Win Multiplier
  • Christmas Tree with red and blue frame = 1 extra Bonus Spin with a 1x Win Multiplier

Whether you get more Wilds or Scatters, this bonus round can definitely give you more rewards compared to the typical Bonus Spins features.

Bonus Buy Feature

Another feature that can make you enjoy the game more is this Bonus Buy which offers more opportunities to play the bonus games. As its name suggests, this provides a chance for players to trigger the bonus round in an instant anytime by buying it instead. Therefore, they don’t have to wait for the special symbols to land and trigger the bonus features.

But just like other Bonus Buy features, this comes with a payout that is worth 100x your stake. Once activated, you will receive your Bonus Spins and the RTP will increase to 97%. Thus, the amount of returns is still good enough to tempt players.

Santa’s Stack RTP, betting and prizes

Santa’s Stack can be played in its 8×8 grid with a built-in cluster pays system. Wins are paid and removed from the reels after landing a cluster with 5 or more matching symbols to welcome new falling symbols. You can start by playing with a minimum bet of £0.10 or increase it up to £50 on each spin. This game has a return to player percentage that is set at 96.26%.

But as mentioned above, this can increase to 97% if you opt to buy the Bonus Spins round. This average RTP is combined with a 23.97% hit frequency so wins can occur once in 4 spins. This slot also has high volatility so winning and playing with the maximum bet pays up to 20,000x your total stake. This is also possible with the help of bonus features since the Cascades continue as long as there is a new winning combination.

The least paying symbols include the lightbulbs and landing these 60 similar symbols will pay you 70x to 1,250x your total stake. Its higher-paying symbols that include Santa and other premium characters pay 2,000x to 10,000x the stake for 60 similar symbols. Its Wild, Bonus, and Mystery symbols don’t have individual values but these special symbols are there to help boost your winnings.


This slot has a list of features and prizes that you can feast on this holiday season. Even if it’s not, this game can still make you feel like you are really into it. Even though a Christmas-themed game is already common in slots, Relax Gaming still managed to make it entertaining. In fact, Santa’s Stack is not the typical slot that other software providers simply reskin from their previously released slot that became successful.

Santa’s Stack has a nice hit rate that is boosted by its features especially by the Mystery symbols and Re-Spins. As you get more Wilds, the bonus round also gets better. You can even get a higher Win Multiplier that is applied to your current wins. Thus, this game can give you a lot of presents you can unbox under the Christmas tree.
