Megaways Slots Explained — How They Work

Megaways slots use Big Time Gaming's licensed reel engine to produce a variable number of symbols on each reel every spin. A standard 6-reel Megaways game changes the reel heights randomly on every spin — from 2 to 7 symbols per reel — producing up to 117,649 ways to win. Some titles expand to 248,832 ways or beyond.

How Megaways Works Mechanically

Traditional slots use fixed paylines — a 5x3 grid with 20 paylines always pays on those same 20 lines. Megaways replaces the concept of paylines entirely with "ways to win": any matching symbol combination from left to right, regardless of exact reel position, counts as a win.

The number of ways is calculated by multiplying the number of symbols on each reel together. If reels show 7-5-6-3-4-7 symbols: 7×5×6×3×4×7 = 17,640 ways. If they show 7-7-7-7-7-7: 7⁶ = 117,649 ways. This variability is the core of the mechanic.

Cascading Reels (Tumbling Reels)

Almost all Megaways slots combine the engine with cascading reels. Winning symbols are removed from the grid and new symbols fall in from above. If the new symbols form another win, they cascade again. Chains of cascades are the primary win mechanism. During free spins, a win multiplier increases with each cascade — typically starting at 1x and climbing with no cap, making deep cascade chains extraordinarily valuable.

Free Spins and Unlimited Multipliers

The free spins feature is where Megaways slots produce their largest wins. The unlimited win multiplier — present in Bonanza, Extra Chilli, White Rabbit, and most BTG Megaways titles — means the 10th cascade in a free spin pays 10x the base, the 20th pays 20x. Theoretically there is no ceiling.

In practice, multipliers of 50x-100x during a free spins session are achievable. Multipliers of 200x+ are rare. The 50,000x max win on Bonanza Megaways requires an extended cascade chain at or near maximum ways during free spins with a very high multiplier.

BTG vs Licensed Megaways

Big Time Gaming created Megaways and licenses the engine to other providers. Pragmatic Play, Blueprint Gaming, Red Tiger, iSoftBet and others all produce Megaways titles under licence. BTG retains creative control of their own titles (Bonanza, Extra Chilli, White Rabbit, Millionaire) while licensees adapt the engine to their own themes and feature sets.

Licensed Megaways often modify the mechanic — Dog House Megaways adds sticky wilds, Buffalo King Megaways uses a persistent multiplier, Eye of Horus Megaways integrates a jackpot network. The core variable ways engine remains consistent across all licensed titles.

RTP and Volatility

Megaways slots are almost universally high or extreme volatility. The variable ways structure means more of the theoretical return is concentrated in infrequent large wins rather than frequent small ones. RTPs cluster around 96% for licensed titles. White Rabbit Megaways (97.39%) is the notable exception at the high end.

Honest expectation: you will have more losing sessions in Megaways slots than in low-volatility alternatives. The rare free spins sessions with 20x+ multiplier cascades compensate — but they are rare. Budget accordingly.
