MAQUINAS TRAGAPERRAS
Santa’s Stack is a Relax Gaming slot built on an 8x8 grid with Cluster pays. The official page confirms it is a Video Slot, with bets ranging from £0.10 to £50, wins in clusters of five or more symbols, Wilds, Respins, Free Spins and a displayed potential of up to 20,000x.
Figures not visible on the Relax page are treated with caution: the 96.27% RTP, High volatility and 23.97% hit frequency come from public product cross-references. As always, the operator's in-game help remains the priority if an RTP variant is supplied.
The real draw of Santa’s Stack is therefore not just its Christmas theme. It is, above all, the combination of a dense grid, clusters, mystery symbols and the Secret Santa Feature, with a profile that is clearly more volatile than a small fixed-line slot.
What we actually know
The basics of the game are easy to read: you need to form clusters of at least five identical symbols. When a cluster wins, what follows can become more interesting thanks to Wilds and Respins, but returns remain heavily dependent on big connections on the grid.

Secret Santa Feature and Respins
The Secret Santa feature is the most distinctive driver. When a Wild is part of a winning cluster, the relevant cluster can transform into locked mystery symbols for a respin. If a new cluster hits this zone, it can join the set and extend the sequence.
This mechanic explains why the game can remain quiet for several spins and then shift to a much more dangerous grid if clusters connect. This is also the reason why the 20,000x potential should be read as a highly ambitious ceiling, rather than a common session benchmark.
Free Spins and Bonus Buy
The Relax page indicates that 3 or more Christmas Trees trigger the Free Spins with 5 free spins. The more trees there are, the higher the number of free spins, with an announced maximum of 8. During this sequence, the Secret Santa Feature remains central to the progression.
The Feature Buy is also confirmed by Relax Gaming. Bigwinboard indicates a cost of 100x the reference bet and a 97% RTP for the purchase, but this option depends on the casino, jurisdiction, and the version served.
Our quick opinion
Santa’s Stack has a good search angle: the exact title, the provider, the grid, the Cluster mechanic, and the Secret Santa feature are confirmed by the official source. Useful secondary figures are present, but are clearly flagged as cross-references when Relax does not display them publicly.
To stay with Relax Gaming, compare it with Sherlock Bones, Shark Wash, Snake Arena or Sloth Tumble. The slot machine hub, the best online casinos and the online casinos France page then allow you to place the game within a wider casino selection.
