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. This creates up to 117,649 ways to win per spin, with the exact number changing every round. RTP (Return to Player) is the percentage of total wagers a slot returns to players over time. For example, a slot with 96% RTP will, on average, return £96 for every £100 wagered across a large number of spins.
