Santa's Stack slot

The 8-reel, 8-row game board comes with Cluster Pays so there are no paylines. You get payouts by placing clusters anywhere on the grid, and they must contain at least 5 matching symbols and the largest combinations have 60+ symbols. The wild symbol is used for all standard symbols to help make winning clusters more often.

To start this pixel adventure you need:

• Open the Santa's Stack here for Demo or in casino to play for real
• Check out the paytable and rules
• Choose the stake size: from 0.10 to 50
• Spin the reels!

You will have to make an effort to make the Cluster Pays mechanics work to your advantage, since the slot comes with high volatility, but each cluster created will bring a large prize. As for the RTP, it is 96.27%, which is higher than the market average. In general, the mathematical model of this game would be ideal for high risk/reward players.

Re-Spins

The re-spins feature will start as soon as the Wild symbol becomes part of the winning cluster. All winning symbols are transformed into Sticky Mystery symbols and the rest of the positions on the playing field are changed. If the winning cluster is next to the Sticky Mystery Cluster, it also transforms into Mystery-locked symbols. This triggers extra re-spins, and Mystery symbols are revealed as a random matching payout symbol when Mystery symbols are no longer generated.

Free Spins

As soon as 3 or more Scatters appear on the grid (anywhere) you get 5 free spins, plus 1 extra free spin for each additional trigger symbol in excess of the minimum 3.

You are guaranteed to get Wild for every free spin, and this increases your chances of getting the Re-spins feature we described above. You start with 1 guaranteed Wild symbol on the 1st free spin, and it increases by +1 for each additional free spin.

You can also get 3 different Christmas tree Scatters during this bonus and they will add +1 to your free spins and / or increase your overall win multiplier by +1.

Bonus Buy

Players living in jurisdictions where it is not prohibited can use the Bonus Buy option by paying 100x. For this amount, they will receive at least 3 Scatters in the next spin and an RTP of 97%.

This game has high volatility so if you still don't feel ready to play for real money, we advise you to first try it in the demo mode, which is already on this page! Just click "Play Demo" and start testing this game without spending a cent. You can familiarize yourself with the gameplay and just have fun by making bets with “fun” coins. Have a fun session!

The ability to get up to 10,000x with just 1 cluster is impressive to us, and in order to unleash the potential of 20,000x, you will need to activate a bonus round where there is a 2x multiplier that can give you a max prize for 1 spin. Good luck!

Santa's Stac's pixelated charm will surely be strong for you, and it's not often that a studio bothers to create a brand new game to get some extra cash for the winter season. This Christmas game is good enough to keep players engaged all year round, and it is definitely a contender for the best Christmas slot of 2021!

Of course, we have seen how Mystery symbols work many times before, but here it is done cool and with great potential. Up to 10,000x out of 1 cluster is impressive, and the total potential of 20,000x is just wow.
