Santa's Stack

Layout

The game offers an 8×8 reel grid with a Cluster win system which means that a minimum of 5 identical and grouped symbols are required to obtain a prize. This win is followed by a Cascade function, which consists in removing the winning symbols to let new ones appear and thus provoke sometimes winning combinations.
The atmosphere of the game is not the only solid element of Santa’s Stack, we can find a RTP of 96.27% which can even increase to 97% with the bonus buy-in option, high volatility and a maximum reward of 20,000x the bet.

In terms of symbols and paytable, there are some nice things representative of the universe with Santa Claus, the grandmother, the elf and the reindeer as high-pay symbols. Red, green and blue lights will pay lower rewards. Another interesting symbol is the Wild substitute that can replace the standard symbols in the game. You’ll need to wager between $0.10 and $50 per spin.

Added to that, Free Spins and the Secret Santa feature will be like the icing on the cake.

Features

Secret Santa Re-Spin

Triggered when a Wild is part of a winning combination, Secret Santa mode turns the winning symbols into mystery symbols and causes a re-spin with the mystery symbols locked in place.

Each time a new prize appears next to the mystery symbols, the winning pool of mystery symbols expands with these new symbols and another re-spin occurs. When there are no more new winning groups including Wild or adjacent mystery symbols, the re-spins end and all the mystery symbols are turned into one big winning symbol.

Free Spins

Free spins are triggered with 3 or more bonus symbols on the reels. Win 5 free spins and each additional bonus symbol allows you to hit an additional free spin.
During the free spins, the Secret Santa is activated and the wilds are guaranteed to appear at the beginning of each spin. The number of guaranteed wilds increases by 1 on each spin.
When additional bonus symbols appear during the free spins, you will receive additional prizes in the form of an additional spin, multiplier or both combined.

The bonus buy-in option is available for 100x the bet if you’re the type of person who can’t wait to unwrap your gift on Christmas Eve!
