How Megaways Slots Work
Big Time Gaming's Megaways engine introduces a radically different win system from traditional slots:
- Variable reels: on each spin, every reel randomly gets 2 to 7 symbols.
- Variable ways to win: the number of winning combinations changes each spin — from 324 to 117,649.
- No fixed paylines: you win with any combination of identical adjacent symbols left to right in any position.
- Tumbling reels: almost all Megaways use the cascade mechanic — winning symbols disappear and those above cascade, allowing multiple wins from the same spin.

Original BTG Megaways vs Licensed Megaways
Not all Megaways slots are equal. The original BTG Megaways (Bonanza, White Rabbit, Extra Chilli, Danger High Voltage) have a maths design that defined the genre. Licensed Megaways (Gonzo's Quest, Buffalo King, Book of Atem) use the same engine but with the licensee provider's own maths — variable quality.
As a general rule: original BTG Megaways have more balanced maths; Pragmatic Megaways tend toward higher max wins but lower RTP.
