Loki s Riches by Pragmatic — RTP & Analytics

Loki's Riches by Pragmatic Play features a 7x7 grid with cluster pays, where wins form from at least five identical symbols connected horizontally or vertically. Tumbling reels remove winning symbols after payouts, allowing new ones to drop in and potentially create chain reactions until no further wins occur. A special expanding symbol randomly activates in the base game, selecting a pay symbol that expands into a 2x2 block at the end of tumbles without exploding, boosting cluster sizes for higher payouts. Free spins trigger with four or more scatters, awarding 10 spins with a pre-selected special expanding symbol active throughout; additional scatters retrigger more spins. Bonus buy allows direct access to free spins for 100x the bet. Visuals depict a Norse mythology theme with Loki positioned to the right, a rocky Northern Lights landscape shifting to a red lava scene in free spins, accompanied by symphonic soundtracks. High volatility leads to infrequent but large wins up to 10,000x, with base game hit frequency of 1 in 2.9. The special expanding mechanic distinguishes it by reliably generating larger clusters without wilds, though the feature set remains relatively sparse compared to other cluster slots.
