Power of Thor Megaways Slot by Pragmatic Play

A two-position-wide hammer sits on the independent top row above reels 2 through 5. When it lands fully in view, every symbol on the reels directly below it converts to Wild. That's potentially two full columns of wilds in one shot. And because the Megaways engine runs tumbles after each win, those wilds can set off chain reactions - clearing winning symbols, dropping new ones in, and if the hammer shifts position after a tumble, transforming a fresh set of reels underneath. The hammer works in both the base game and free spins, which gives the base game more action than you'd expect from a standard tumble slot.

Four Scatter symbols spelling T-H-O-R trigger 10 free spins. Five or more push that higher, up to 30. But before the round begins, a gamble wheel appears if you've won between 10 and 18 spins. Win the gamble and you add 4 more spins. Lose and you forfeit the entire round. The odds aren't bad - 62.8% on the first gamble, climbing to 75% on the third - but walking away empty-handed is a real outcome. During free spins, a progressive multiplier starts at 1x and ticks up by one with every tumble. Late in the round, a single tumble chain touching hammer-converted wilds can stack several multiplier bumps in a row. Three Scatters during the round retrigger with 4 extra spins.

For 100x your bet, the buy option skips straight to the bonus with a random 10 to 22 starting spins. The gamble wheel still appears after purchase, so you can push for more if you want the risk. Rolling green hills and stone ruins stretch behind the wooden reel frame, with Viking metalwork accents and rune stones along the borders. Thor himself stands to the right of the grid - golden beard, horned helmet, crackling lightning around his hammer. Premium symbols are painted character portraits of Norse warriors and a shield maiden, while the low-pays use card values (9 through A) rendered in ornate Celtic metalwork with distinct purple, green, blue, and red tints. The reels shift between 2 and 7 symbols per spin, and the Megaways counter updates in a gold badge at the top right. Most spins land somewhere around 1,000 to 3,000 ways, with the full 117,649 showing up when all six reels hit maximum height. Great Rhino Megaways uses a similar tumble-plus-multiplier structure but without anything like the hammer conversion.
