Revenge of Loki Megaways Slot by Pragmatic Play

Four Scatter symbols spelling L-O-K-I trigger 9 free spins, with each extra Scatter adding 3 more up to 18. Before free spins begin, a gamble wheel offers the chance to increase the count by 3 at a time - but losing means forfeiting the entire round. Bought rounds skip the gamble entirely and lock in a fixed number of spins.

The Loki Super symbol drives the core mechanic. It lands exclusively on the independently spinning bottom row beneath reels 2 through 5, and when it appears, it fills every position on the reel above with Wilds. In the base game, it also randomly transforms one or more high-paying symbol types into a single premium symbol for the current tumble sequence. During free spins, those transformations become permanent - each time Loki Super hits, another tier of symbols merges, progressively concentrating the paytable into fewer, higher-value icons.

A separate Loki symbol appears only on reel 6 during the bonus. It doesn't pay directly but awards 1-2 extra spins or adds a +1x or +2x multiplier that stacks and applies to every winning combination in that tumble chain. The multiplier resets between spins but can build quickly when tumbles keep going.

The Megaways engine runs on a 6-reel grid where reels 1 and 6 hold up to 7 symbols while reels 2-5 hold up to 6, creating a theoretical maximum of 117,649 ways. The bottom row spins right to left independently from the main reels, adding an extra layer of unpredictability to Loki Super appearances.
