Inside the game

Captured in the studio's own free demo on 13 September 2026. Nothing below is taken from a press release or another site — it is what the game shows when you open it.

The base gameA single reel, standing in a snowy mountain pass, stopped on the woolly rhino's head. On the left, the three progression ladders under their animal: a first one with russet fur from x1 to x12, the sabre-toothed cat from x3 to x100, the rhino from x10 to x250, beneath a JACKPOT shown at 50. The bank reads 0, the bet 0.1, and the COLLECT button pays the bank into the balance.
How to playHOW TO PLAY: the Spin button turns the single reel and the symbol that lands moves its bar up one level; Collect transfers the money from the bank to the balance but resets the whole progression; the bet cannot be changed while the bank is not empty. PROGRESSIVE SYMBOL WINS opens below on the three bars — cyan, purple and orange, one per animal.
Game rules, page 2The progression mechanic, stated in four points: three symbols with progressive wins, one level up each time the symbol lands on the reel, all winnings accumulated inside the bank except direct wins and the jackpot, and a Collect that pays the bank out while resetting the levels. Then SPECIAL SYMBOLS: the Wild, the head of the mammoth with its curved tusks, counts as all three win symbols at once and moves each of the three bars up a level.
Special winsThe Reset Bank symbol, a carved block of ice: landing it resets all prize progression and sends the bank back to 0. Below, SPECIAL WINS: once a symbol has reached its final level, every further landing pays that level straight to the balance without going through the bank; filling all three bars awards the jackpot, which then disappears until the prizes are reset, by Collect or by the Reset Bank symbol.
