Megaways is a slot mechanic developed by Big Time Gaming (BTG) that generates a variable number of symbols on each reel every spin, producing up to 117,649 ways to win on a six-reel game. The mechanic was licensed to other providers from around 2017 onwards and has since been used by Blueprint, Red Tiger, Pragmatic Play, Relax Gaming and dozens of others. There are now hundreds of Megaways titles available to UK players.
Understanding the Megaways mechanic helps you set realistic expectations. The huge win potential comes primarily from the unlimited multiplier that builds during free spins in most implementations — Bonanza Megaways, Extra Chilli, and others accumulate a multiplier each time a cascade win occurs. In practice this means 99% of bonus rounds end with modest wins and occasional rounds produce the headline-grabbing results you see in streaming videos. The variance is genuinely very high, and the average bonus round payout in Bonanza Megaways is around 20x to 30x stake, not the 5,000x maximum.
From a pure RTP perspective, many Megaways slots are competitive: White Rabbit Megaways sits at 97.72%, Rainbow Riches Megaways at 96.99%, and Bonanza at 96.0%. These are solid figures compared to the wider slot market average of around 95% to 96%. The volatility is what makes them difficult to manage on limited session budgets.
The Megaways titles consistently rated highest by our UK community are Bonanza Megaways, Extra Chilli Megaways, and Fishin Frenzy Megaways for balanced play. For maximum variance and potential: Money Train 2 Megaways and Dead or Alive 2 (not technically Megaways but similar very-high-variance profile). All are available at the major UKGC licensed casinos in the table above. Check individual thread discussions for current bonus frequency data from community members.
