Trollheim Slot by Rival

The hook lives in one line of copy the game makes no secret of: three separate bonus games that can fire at the same time. Each one is its own free spins mode, triggered at random by landing a matching colored troll gem. Blue gem gives you 8 spins carrying the Avalanches over from the base game. Gold gem gives you 8 spins wired to the jackpot ladder. Red gem gives you 8 spins with an Extra Free Spin symbol that stretches the round. Nothing forces you to pick one. Land two gems, or all three, and the modes layer, so you can end up in Jackpots plus Avalanches, or the full stack of all three at once.

The jackpot side is where the "Power Pots" subtitle earns its name. Five tiers run down a ladder on the left edge - Mini at 50x, Minor at 100x, Maxi at 150x, Major at 500x, and a Grand above that. During the Gold-gem spins, landing jackpot troll symbols fills the matching tracker. Fill it and that pot pays instantly. And each tier can be won more than once in the same round, so a hot Gold-gem run isn't capped at one hit per pot.

Underneath all of that sits the Avalanches. Winning symbols clear out, new ones drop into the gaps, and a single spin can chain several wins before it settles. It runs in the base game and carries into the Blue-gem mode. The Wild is a stacked troll totem, two symbols tall, which on a five-reel board means one landing can blanket a whole reel and stitch together avalanche chains that would otherwise break.

No buy button here, which is worth knowing before you go hunting for one. Every bonus comes from actual gem drops, so the free spins arrive on the game's terms, not yours.

The art is dark fantasy dungeon work from Rival - a gem-lit troll cave of craggy stone pillars, molten cracks in the rock, and glowing crystal veins in purple and teal. The trolls themselves are chunky 3D renders, grinning blue and green and red, sat beside a gold crown, an overflowing treasure chest, and rune-carved stones. Even the low card royals get the stone-carved treatment instead of the usual flat letters.
