Megaways is a random reel modifier mechanic originally developed by Big Time Gaming. Instead of a fixed number of paylines, each reel shows a random number of symbols on every spin — typically between 2 and 7 — creating up to 117,649 different ways to win on a single spin. Many providers now license the Megaways engine from BTG.
Most Megaways slots offer up to 117,649 ways to win (7 symbols on each of 6 reels: 7^6). Some variants push even higher — Megaways slots with extra top reels or expanding symbol counts can exceed 200,000 ways. The number of active ways changes with every spin.
Most Megaways slots are medium-high to high volatility. The variable reel sizes mean wins can be infrequent but substantial when they land, especially during free spins with cascading wins and increasing multipliers. They are best suited to players with adequate bankrolls who enjoy high-risk, high-reward gameplay.
White Rabbit Megaways by Big Time Gaming holds one of the highest RTPs at 97.72%. Extra Chilli Megaways (96.82%) and Big Bass Bonanza Megaways (96.71%) also rank among the best. Always check the RTP in the game's info screen, as some casinos use reduced-RTP versions.
Yes. All modern Megaways slots are built with HTML5 and are fully optimised for iOS and Android devices. The gameplay experience, including cascading reels and bonus rounds, works identically on mobile browsers and casino apps.
Cascading reels (also called tumbling or avalanche reels) remove winning symbols after a payout and drop new symbols into the empty positions. This can create chain reactions of consecutive wins from a single spin. In many Megaways free spins rounds, each cascade increases a win multiplier.
