In detail
Common UK slot mechanics include classic paylines, ways-to-win (243 or 1024 ways), Megaways, cluster pays, infinity reels, and hold-and-spin features (Pragmatic's Bonanza series, Reel Kingdom's Big Bass series). Each mechanic has typical variance and hit-rate signatures. Modern slots often combine mechanics — cascading reels with multipliers, expanding wilds inside Megaways.
