Although Christmas-themed slots are nothing new, Santa’s Stack stands out from the titles that we typically see appearing at this time of the year as it uses console game-style graphics that hark back to the 80s.

It also boasts some pretty fun special features like free spins and Secret Santa respins. Plus, there are cluster wins and cascades.

Winning combinations of 60 symbols or more help you to fill your stocking with tasty prizes, and mobile players are catered for too as Relax Gaming has optimised the game for all device types.

You can play Santa’s Stack with bets of 10p to £50 per spin, although it’s designed to be a highly volatile slot, so you may prefer to play with smaller bets to start with. The RTP (Theoretical Return to Player) is nice and high at 96.27%, and although it can be boosted even further to an impressive 97% through the buy-in feature, software developers are no longer allowed to offer UK players buy-in bonuses.

We can’t wait to tell you more about this fun festive slot. So, make sure you continue reading our Santa’s Stack slot review for the full story!

How to play

As the Santa’s Stack slot uses Cluster pays rather than paylines, you don’t need to worry about how many paylines to play with. You do, however, need to choose how much you wish to stake before you start playing, and the game gives you a variety of options: 10p, 20p, 30p, 50p, 80p, £1, £1.50, £2.50, £5, £8, £10, £12.50, £15, £20, £30, and £50.

The game uses 8 reels and up to 8 symbols can land on each reel. As the symbols often land in stacks, this makes it possible to create significant winning combinations.

If you check the bottom of the screen, you’ll see a row of buttons that run from left to right. They include the menu (where you can view the rules and paytable, alter your stake, and toggle the music and sound effects off and on), the volume button, the stake options, the spin button, the current win amount, and your remaining balance.

The Buy Feature and Auto-Play are both disabled for UK players due to new gambling regulations.

The symbols on the reels of this game are…

all typically Christmassy as you would expect

  • Father Christmas
  • Mrs Christmas
  • Elf
  • Reindeer
  • Red light
  • Green light
  • Blue light
  • Gift Box
  • Christmas Tree

Jackpot

Santa’s Stack is not a progressive jackpot slot, nor does it offer any fixed jackpots. However, it does boast a generous maximum win of 20,000 times your total stake.

Special features

Santa’s Stack offers something for everyone, thanks to it having several special features along with a Cluster Wins game mechanic:

Cluster Wins

Clusters are formed when at least 5 matching symbols land anywhere on the grid and are touching either vertically or horizontally. As you can see by looking at the paytable, each symbol offers a different cash prize. If you manage to land 60 or more of the highest-paying symbols (Father Christmas) in a single cluster, you can win as much as 10,000 times your total stake!

Wild Symbols

The wild symbol in the Santa’s Stack slot is the red-and-yellow gift box marked “W”. The wild symbol can replace all other symbols apart from the scatter when it can help to create a winning cluster.

Secret Santa Feature

The game’s innovative and entertaining Secret Santa feature is awarded every time that a wild symbol contributes towards a winning cluster. It converts the winning cluster into mystery symbols before giving you one respin with all the mystery symbols held in place.

If a new win occurs next to the mystery symbols, the new win also transforms into mystery symbols and awards an extra respin.

When no more winning clusters can be created, the mystery symbols all change into the same randomly chosen paytable symbol.

Free Spins Bonus

The Free Spins Bonus is triggered when at least 3 scatter symbols land anywhere in view. The scatter is represented by the Christmas tree. You receive 5 free games for 3 triggering scatter symbols and 1 extra spin for every additional scatter symbol.

The Secret Santa Feature that we mentioned above is active throughout the Free Spins Bonus. You’re also guaranteed at least one wild symbol at the beginning of each free spin, and the number of wilds increases by one with each consecutive spin.

If a scatter symbol lands while the Free Spins Bonus is underway, you receive a +1 multiplier, an extra free spin or an extra free spin along with a +1 multiplier.

Graphics and Sounds

Santa’s Stack takes you to the central square of a quaint and picturesque town with snow-topped buildings and fairy lights strewn across the street. The clever animations allow snowflakes to fall in front of your very eyes and there’s a rather charming and Christmassy tune that plays while you spin the reels.

The paytable symbols all use a festive theme too, and they range from Father Christmas and Mrs Christmas (or Mrs Claus as she’s sometimes known), a cheeky elf, a cute reindeer, and three coloured fairy lights.

You can quickly mute the music and sounds by clicking on the speaker button at the bottom of the screen, and in the same area, you can increase or decrease the size of your stake between spins.

Conclusion

It’s great to see a Christmas slot that offers something different from the norm, particularly when there are so many re-skins about.

The blend of old (with the retro symbols) and new (with Cluster Wins and mystery symbols) make for an exciting and unusual playing experience, and the top jackpot of 20,000x your bet is way more generous than your typical stocking-filler.

Look out for Santa’s Stack appearing at your favourite online bingo sites very soon!
