The Megaways Mechanic: Why 117,649 Ways Became an Industry Standard
Big Time Gaming licensed a single reel mechanic to half the industry. Here is how cascading variable reels changed slot design and why the copycats feel different.
A variable grid instead of a fixed one
Traditional slots fix the number of symbols per reel. Megaways lets each of the six reels show between two and seven symbols on every spin, so the number of winning combinations changes constantly — peaking at 117,649 when all six reels land seven symbols.
That single change did two things at once: it made every spin visually different, and it let designers build enormous top-end payouts without touching the base game hit rate.
Cascades keep the round alive
Winning symbols are removed and replaced by symbols falling from above, which can trigger another win. Chained together with an unlimited multiplier during free spins, a single spin can run for thirty seconds and produce a payout several thousand times the stake.
The mechanic did not make slots more generous. It made them more dramatic — and drama is what sells.
Why the licensed versions vary so much
Studios license the mechanic, not the maths. Each one builds its own paytable, volatility profile and feature set on top, which is why two Megaways titles from different studios can feel nothing alike despite sharing the headline number.
- Reel modifiers — some add extra rows or persistent multipliers.
- Feature buy — many versions let players purchase the bonus directly.
- Volatility — ranges from moderate to extreme across licensed titles.
What came next
The success of variable-reel design pushed the whole industry toward configurable grids: cluster pays, expanding grids, infinity reels and hybrid formats all trace back to the same insight — that a fixed 5x3 grid was a constraint nobody actually needed.
