Secret Sauna Slots

Secret Sauna is an online Slot from Slotmill.

Secret Sauna is a Slotmill cluster pays slot on a 7x7 grid, built around two brothers keeping up their Christmas sauna tradition while the snow piles up outside. Winning clusters clear away in Avalanches, and Wilds leave glowing Hotspots behind that come back as fresh Wilds once the cascades stop.

How the Game Plays

Wins form when 5 or more identical symbols connect horizontally or vertically. The pay symbols are blueberries, gooseberries, cranberries, blackberries, helmets, flasks, sausages, boots and reindeer. Winning symbols are removed and new ones drop in, so one spin can run through several Avalanches. Wilds substitute for every pay symbol. Any Wild that is part of a win leaves a Hotspot on its position, and when the last Avalanche of the spin is over all Hotspots turn into Wilds, which gives the grid one more chance to pay. Free Spins symbols are collected in a meter beside the reels and also trigger an Avalanche as they are removed.

Free Spins and Super Free Spins

Three, four or five bonus symbols award 6, 8 or 10 free spins. In the bonus, Hotspots created by winning Wilds stay on the grid until the round ends. Each new Wild that lands on a Hotspot adds a multiplier to it, climbing from x2 to x3, x4 and higher. After the last free spin every Hotspot becomes a Wild and keeps its multiplier, and multipliers in the same cluster multiply together, so x2 and x3 make x6. If one of the triggering symbols is a Super bonus symbol, the round plays as Super Free Spins with at least 2 Wilds guaranteed on every spin.

Fast Track and Xtra-Bet

Fast Track lets you buy a spin that triggers Wild Hotspots for 10x the bet, the Free Spins for 100x or the Super Free Spins for 400x. Xtra-Bet raises the stake by 50% and makes the Free Spins 2.9 times more likely to trigger, and it cannot be used with Fast Track. Burst Mode speeds up play and shows only the total win of each round.

How do Wild Hotspots work in Secret Sauna?
A Wild that is part of a winning cluster marks its position with a Hotspot. Once the final Avalanche of the spin ends, every Hotspot becomes a new Wild, which can start another round of wins.
How do you trigger the free spins?
Land 3, 4 or 5 bonus symbols for 6, 8 or 10 free spins. Hotspots stay on the grid for the whole round and pick up multipliers each time another Wild lands on them.
What is different about Super Free Spins?
They start when one of the triggering bonus symbols is a Super symbol. The Hotspot rules are the same, but at least 2 Wilds are guaranteed on every spin.
Can you buy the bonus in Secret Sauna?
Yes. Fast Track sells a Wild Hotspots spin for 10x, the Free Spins for 100x and the Super Free Spins for 400x the bet. It cannot be combined with Xtra-Bet.
