Ragnarok

Slotmill built Ragnarok around Norse mythology's ending, the battle between gods and giants that gives the game its name, staging the whole event in a mountainous setting complete with a glowing stone formation for atmosphere. Cluster pays run on a 5x5 grid: five or more matching symbols touching each other anywhere on the board form a win, rather than paying along fixed lines.

The paytable runs three carved stone-block symbols as the lower tier, three stone-faced character symbols above them, and a single flame-eyed character as the top prize. A cluster of exactly five matching symbols pays between 0.15x and 0.4x the stake, while the largest clusters of twelve or more climb to 5x-12.5x — modest cluster values on their own, which is where the game's multiplier system does the real work. The Avalanche mechanic clears winning symbols off the board and drops new ones in from above, repeating for as long as fresh clusters keep forming.

Each Avalanche win drops a wild symbol into one of the freshly opened spaces before the next round of symbols falls, and that wild substitutes for everything except the free spins scatter. Every Avalanche win also doubles a progressive multiplier that resets to 1x at the start of each new base-game spin, so a long chain of avalanches can build serious value before it ends. Loki's Trick can activate at the start of a round to bump that multiplier up by a random number of steps, and giant symbols — 2x2 or 3x3 blocks that count as four or nine symbols respectively — can appear at the start of a round or once a round's wins have dried up.

The scatter count decides the free spins tier: three lands 8 spins, four lands 10, and five lands 12. The multiplier doesn't reset between spins during the round, carrying over until the feature ends, though scatters don't appear on the reels once free spins are underway. For players who'd rather buy in directly, Fast Track offers five paid entry points into the game's mechanics: a guaranteed giant symbol for 5x the stake, guaranteed Loki's Trick for 25x, entry to the free spins round for 100x, a version guaranteed to start with 5 scatters for 400x, and a 50/50 gamble spin for 200x that either lands the 5-scatter free spins or nothing at all — each option carrying its own RTP between 96.12% and 96.45%.

Betting runs from 0.20 to 60 per spin, with an Xtra-Bet option that raises the stake by 50% in exchange for a free spins trigger roughly three times more likely, alongside a Burst Mode for faster spin cycles. Ragnarok's base RTP runs between 96.1% and 96.12% depending on the Xtra-Bet setting, volatility is rated high, and the maximum win is 10,000x the stake.
