Megaways slots use a dynamic reel mechanic that randomly changes the number of symbols on each reel with every spin — typically between two and seven. High-volatility slots pay out less often but can deliver significantly larger wins when they do. For example, a slot with 96% RTP will, on average, return £96 for every £100 wagered across a large number of spins. These may feature free spins, re-spins, pick-one bonuses, or trail features.
