Short answer: Megaways slots change the number of symbols on each reel every spin, giving up to 117,649 ways to win. None of the seven slots we review in full is a Megaways game; the mechanic belongs to Big Time Gaming, and many studios use it under licence.
How Megaways works
Each of six reels shows two to seven symbols, and the ways to win are the reel heights multiplied together. Wins cascade: winning symbols vanish and more drop in.
High volatility and long quiet spells. Megaways titles are named in Coral's listing and reported across the other sites.
In more detail
A spin with reels showing 7, 7, 7, 7, 7 and 7 symbols gives the full 117,649 ways; one showing 2, 3, 2, 4, 3 and 2 gives just 288. That constant change is the point. Many Megaways slots add an extra horizontal reel above the middle four and an unlimited multiplier in free spins, which is where the largest wins come from.
