Introduction

Relax Gaming’s Santa’s Stack is a high variance cluster-based slot where landing five or more matching symbols in a group will award wins. The games panel comprises eight rows and eight columns and gets based on Christmas, where you get to enjoy elves, flashing lights and red-nosed reindeer filling the reels. There are also many bonus features, including Free Spins, Multipliers and Re-Spins. The Santa Stack has an RTP of 96.27% and a hit frequency of 23.57%, but the gift is the maximum win potential of 20000x your stake.

Santa’s Stack Bonus Features

This retro designed slot has two bonus features and a chance to buy the feature. The first Bonus feature is the Re-spins feature, where the Wild symbols assist in some big prizes. This feature gets triggered when a wild is part of a winning cluster, which converts into mystery symbols, and a Re-spin gets granted. All the symbols in the cluster are Christmas presents until the Mystery symbols get revealed. The Mystery Symbols remain on the reels, and this process continues until no new winning clusters get formed.

The Free Spins get triggered when you land three or more Christmas Tree Scatters. There is a Bonus area with three stars to the left of the screen, and the starts get filled when you land the 3 Scatters and receive 5 Free Spins initially. In Santa Stacks, you receive another Free Spin whenever you land a new Scatter. The Secret Santa feature is also active during the Free Spins round, and players are guaranteed to land them at the start of every spin.

Buy Feature

A Buy Feature is available, allowing you to buy the Free Spins feature. The RTP during this feature increases to 97.00%; however, it is not available to players based in the UK.
