How do you win in Santa’s Stack?

This is a cluster game on an 8×8 grid where you win when 5 or more matching symbols connect in a group. There’s no need to worry about paylines, you just form a cluster, so the rules are intuitive. Wilds, respins, and the Secret Santa feature help your wins along. If you like clusters among Relax Gaming slots, this holiday-themed game is one you’ll reach for first. With such a wide grid, you’ll often see symbols pile up on one side.

When does the Secret Santa feature kick in?

The Secret Santa feature is the key mechanic that showers gifts to help your wins. In free spins especially, it stays active from the very first spin and grows larger with each spin. That means the later you get into free spins, the more likely the gifts are to pour down. The gift boxes showering down also keep the waiting from getting dull. In the base game, wilds and respins keep the flow going.

How many Christmas trees do I need to trigger free spins?

Land 3 or more Christmas tree symbols and you start with 5 free spins. The more trees that land, the more spins you get, up to a maximum of 8. The count itself isn’t large, but Secret Santa grows with every spin, so each spin carries a lot of weight. Don’t be disappointed if the starting count looks low. The number of trees greatly affects the outcome, so watch how many land.

Can I jump straight in with a bonus buy?

Yes, bonus buy is available, so you can jump straight into free spins without waiting for the trees. In the demo, you can use this feature to watch the Secret Santa grow over and over again. If you like tearing open the wrapping quickly, it’s a welcome option. It’s also worth checking that the number of spins depends on the number of trees. Try comparing the flow when you open it with a purchase a few times.

What should I check first in the demo?

The RTP is 96.27%, volatility is very high, and the max win is 20,000x. With a hit frequency of 23.97%, you win roughly once every four spins. The bet range is €0.10 – €50, so in the demo, play a few free spins rounds and see how quickly the Secret Santa grows. Comparing several bonus buys is also a good idea.
