Santa’s Stack is an online slot from Relax Gaming with a cluster format and a top prize of 20,000x. Features including, mystery symbols, respins, free spins and multipliers. The RTP of this highly volatile slot is 96.27%.

Theme and Graphics

Relax Gaming doesn’t often use 8-bit graphics, but we love it when they do. Just like Hellcatraz, Santa’s Stack uses a quirky, retro aesthetic to entertain players in a really fun and unique way.

The game looks amazing, with a quiet 8-bit town sitting in the background as snow lightly falls and gathers on the ground. It almost looks like the setting of a retro video game, so it will certainly appeal to anyone who grew up during the 90s.

This is definitely one of the best-looking Christmas-themed slots we’ve seen. It really puts a new twist on the holiday theme and we can see why players would love it.

Santa’s Stack RTP and Variance

The Santa’s Stack RTP is 96.27%. Seeing as payout percentages are starting fall lower and lower (well below 96%), this is a great figure, and we’re glad to see some slot developers sticking to more generous RTPs.

This is a highly volatile slot, as well. It’s rated 5/5 on Relax Gaming’s own volatility scale, providing players a top prize of 20,000x – but wins that come around less frequently (with a win rate of 23.97%) than they would in a lower variance slot.

How to Win

The Santa’s Stack slot from Relax Gaming is a cluster-based game where landing five or more matching symbols in a group will award a win. Of course, Santa is the most generous symbol in the game, providing a top prize of 10,000x. Then comes Mrs Claus, the head elf and Rudolph – paying 4000x, 3000x and 2000x respectively.

Secret Santa Respins

When you land a wild symbol as part of a winning combination, you’ll trigger the Secret Santa bonus. The winning cluster will transform into mystery symbols and then all of them will reveal the same symbols.

Should a new win be made with symbols outside of the winning cluster, they will join the group and all of them will be transformed into mystery symbols. A respin is then awarded, and the process repeats itself.

Free Spins

Landing three or more Christmas Tree symbols on the reels will trigger the free spins bonus. You’ll get 5 free spins for the first 3 scatters and one more for every additional on.

During this bonus, wild symbols are guaranteed to land at the start of every spin – and the number of wilds increases throughout the feature. This means that you can look forward to triggering the Secret Santa bonus a lot more often.

If you land bonus symbols during this round, you’ll receive one of the following:

  • +1 more free spins
  • +1 added to your multiplier total
  • +1 free spin and +1 multiplier

Santa’s Stack Slot Review

Santa’s Stack from Relax Gaming is the hit Christmas-themed slot of 2021, and will continue to be a player favourite for years after. It’s got the perfect mix of whimsy and innovation that is sure to captivate players.

A Less Complicated Hellcatraz

Hellcatraz is one of Relax’s most popular slot games, but it can be a bit complex and overwhelming. There’s a lot going on there – so, if you enjoyed the game’s aesthetic but weren’t into all of the crazy features, then Santa’s Stack is the slot for you.

Great Twist on Mystery Symbols

If you know anything about the reviewers at Slots Temple, you know we’re not keen on Mystery Symbols; they’re usually pretty useless and seem like an afterthought most of the time. However, this isn’t the case Santa’s Stack.

The fact that winning symbols convert into mystery symbols means that they will always result in a win. Then, that win can be built on by landing more symbols in the combination.  Granted, it’s rare to land a string of Secret Santa respins – but, when it happens, great payouts are available.

It’s an interesting twist that we haven’t seen before in other slots. So, it’s certainly worth checking out in Relax Gaming’s Santa’s Stack slot.
