Santa’s Stack Slot Review – Relax Gaming

It has been a couple of weeks since my last Relax Gaming slot review, this was for the game titled ‘Cluster Tumble’. Which has a max win capped at 10,000x and a Free Spins feature with an increasing multiplier. Today we are learning all about ‘Santa’s Stack’, which is available to play now across all sites.

We have another festive slot theme ready for the Christmas period and we haven’t even hit December yet for the start of advent calendars! The game background is set in a snowy village, with buildings decorated with Christmas decorations and a Christmas tree in the middle of the plaza. Visuals have a cartoon-like aesthetic, with bright & bold colours. The reel border is tinsel filled with different coloured lights.

Santa’s Stack has a setup of 8 reels by 8 rows, this includes cluster pays of 5 or more matching symbols. This slot is high variance with a set RTP of 96.27% and a max win capped at 20,000x. You can bet from £0.10 – £50.

There are 9 symbols in total, this includes 3 low-paying symbols. These are represented by blue, green, and red Christmas lights. There are also 4 premium symbols, these are represented by reindeers, elves, Mrs. Klaus and Santa Klaus. In addition to these regular symbols is a Christmas tree scatter and wild symbol. The highest paying symbol is the Santa Klaus premium, which pays 1x – 1,000x for clusters of 5 – 60+. Wilds substitute for all symbols except the scatter symbol.

Santa’s Stack Features

The ‘Secret Santa’ feature is triggered when a wild symbol is part of a winning cluster. When triggered the winning cluster will convert into mystery symbols and a re-spin will be awarded mystery symbols held in place. Every time a win occurs adjacent to the previously formed mystery symbols, the new winning cluster will also convert into mystery symbols and awards an additional re-spin. When no more winning clusters form, respins will end and mystery symbols will all reveal the same symbol.

Landing 3 or more Bonus scatters during a base game spin will trigger the Free Spins feature. Awarding 5 Free Spins, with an additional spin for each extra scatter. During spins, the Secret Santa feature is active and wild symbols are guaranteed to land at the start of every spin. The number of wilds guaranteed to land increases by 1 every spin. Landing bonus symbols can award +1 additional spin, +1 multiplier, or +1 additional spin & +1 multiplier.


Overall, I think this slot is a fantastic release by the studio and includes well-known mechanics. Including a max win capped at 20,000x and Free Spins feature with guaranteed wilds on each spin. Be sure to try out the game for yourself and check out our exclusive casino offers.
