What are Megaways slots?: The ultimate guide

Megaways slots are online slot games that utilise a dynamic reel system, where the number of symbols per reel changes randomly on each spin. Created by Big Time Gaming in 2016, this mechanic generates between 324 and 117,649 ways to win per spin, which is far more than traditional slots with fixed paylines. Some Megaways games like Rasputin Megaways offer up to 2,985,984 ways to win.

How do Megaways slots work?

The Megaways engine randomly assigns between 2 and 7 reel symbols to each reel per spin. With six reels, this creates anywhere from 64 (2×2×2×2×2×2) to 117,649 (7×7×7×7×7×7) ways to win.

Maximum paylines only appear when all reels display seven symbols. You can view the paytable in each game to see symbol values and bonus round triggers. Understanding this mechanic helps you get the most from the best Megaways slots UK casinos offer.
