How to play Santa’s Stack mobile slot

The Santa’s Stack slot gives you 8×8 reels with cluster pays, wild symbols and free spins that can trigger as much as 20,000x your bet, all for a low min spin cost of 0.10 a spin.

Much like the Fat Santa slot that came before it, this Relax Gaming slot game is a strange mish-mash of concepts. The whole thing is set in Christmas Town over a huge 8 by 8 grid game with cluster pay mechanics.

5 or more of the pixelated symbols touching horizontally or vertically will give you a win, but unlike cluster pays slots the symbols don’t explode and you don’t get more for your money, whether spinning 0.10 minimum bet or 50 maximum bet.

What you do get is a retro-looking Santa’s Stack mobile slot machine that may have looked great in an original Super Nintendo back in the 90s, but now is just meant to make you feel nostalgic for simpler days.

Santa’s Stack slot has a top win of 20,000x your bet

How much you’ll enjoy this high volatility slot will depend on how much you like the Secret Santa Respins feature.

if you get a win with a wild symbol, all the winning symbols will stay on screen in the form of a mystery symbol for 1 respin of the reels. If you get another win next to those symbols, they will also turn into mystery symbols.

In that way, you could potentially turn the whole screen into one high-paying symbol, as when the respins end, the game randomly chooses a paytable symbol to switch all the mystery symbols into.

Unlike the Age of Akkadia slot, we genuinely felt like you could walk away with a screen full of wins.

The free spins are where the big wins are hiding

Even if you get 60+ Santas on screen, you’ll probably only get 10,000x your bet. To get the max win in this Santa’s Stack slot, you’ll have to hit 3 or more Christmas tree symbols and trigger 5 free spins.

It’s not a lot, but on every spin in this Santa’s Stack slot, you get a guaranteed additional wild – so one wild in spin 1, two wilds in spin 2, three wilds in spin 3, etc…

The wild helps give you those mystery symbols and those respins, giving you a little bit of value for money. You can pay 100x your bet in order to trigger this bonus, but be careful. This volatile game can pay out 10x your bet more often than 1000x.

As far as Christmas slots go it’s very generous, but it will take a whole load of hard work to prove to this Santa that you’re nice rather than naughty.

Bonus Features

Cluster Pays: When 5 symbols are touching horizontally or vertically, they create a win.

Secret Santa Respin Feature: If a wild symbol is part of a win, this feature is triggered. All the winning symbols change to a present and stay sticky on the screen for one re-spin. If you get more winning symbols next to the secret Santa, they will also turn into secret Santa presents and you'll get another respin of the reels.

When there are no more winning symbols, all the secret Santa symbols will reveal one mystery symbol from the paytable, guaranteeing you a bigger win.

Free Spins: 3 or more Christmas Tree scatters will trigger 5 free spins, and every additional bonus symbol will award an extra spin. During the free spins, the Secret Santa feature is active and wild symbols are guaranteed to land at the start of every spin. The number of wild symbols guaranteed to land increases by one on every spins, starting with one wild symbol.

Landing a scatter will give you either an extra spin, a +1 multiplier, or an extra spin AND a +1 multiplier.

Buy Feature: For 100x your bet you can buy the free spin bonus round.

Santa’s Stack Review Conclusion

We weren't that keen on the retro Christmas video game look, but you can't deny that there's plenty of wins available for anyone looking for a big payout.

You'll need patience though. The Secret Santa Respins can be fairly difficult to get on your side, but if you do manage to build up the stacks, you could end up with 1,000x your bet.

Why did we not say 20,000x your bet? Because for that you'll need the Santa's Stack slot free spins and they are harder to catch than Old Mr. Claus on Christmas eve.

A good addition to the Relax Gaming slots portfolio, but we'd probably still rather play Helios Fury slot for simple fun.
