In 2016, Australian studio Big Time Gaming released Bonanza and quietly changed what a slot could be. A decade later "Megaways" appears on hundreds of titles from a dozen studios. Here's what the label actually means — mechanically and mathematically.

The Core Mechanic

A classic slot has fixed reels: five reels, three symbols each, wins on predefined paylines. Megaways makes the reel heights random on every spin:

  1. Each reel shows 2–7 symbols The height of every reel is drawn fresh each spin — one spin might be 7-7-7-7-7-7, the next 2-3-4-2-5-3.
  2. Ways = reel heights multiplied Six reels of 7 symbols gives 7⁶ = 117,649 ways. The smaller draw above gives 2×3×4×2×5×3 = 720 ways. The counter above the reels shows the current number.
  3. Adjacent-reel wins, any position Matching symbols on consecutive reels from the left pay regardless of where on the reel they land — no paylines to hit.
  4. Cascades follow wins Winning symbols vanish and new ones drop in, allowing chains of wins from a single spin — usually with a multiplier climbing during bonus rounds (unlimited in Bonanza's free spins).

What It Does to the Maths

Here's the part the marketing skips: more ways does not mean more RTP. Most Megaways titles sit at the industry-standard 95.5–96.5% — the mechanic redistributes the return rather than enlarging it:

  • Base game: frequent but tiny wins (many ways, small pays per way) — it feels active while grinding your balance slowly
  • Bonus rounds: carry a large share of the RTP, with climbing multipliers producing the format's signature five-figure-multiplier hits
  • Net effect: mid-to-high volatility with a deceptive low-volatility texture in the base game. Bankroll accordingly — our volatility guide puts Megaways in the 300–500 bet bracket

Titles Worth Knowing

BTG licenses the mechanic widely, which is why quality varies: the label guarantees the reel mechanic, not the game design around it. Studio pedigree still matters — see our provider rankings.

Should You Play Them?

Play Megaways if you enjoy visible action, cascade chains and the dream of a multiplier run — it's arguably the most entertaining volatility package in slots. Skip it if you're clearing bonus wagering (the variance works against you) or running a small bankroll. Every casino we've reviewed carries the major Megaways titles; Stake and BC.Game have the deepest selections.
