The Innovation That Reshaped an Industry

When Big Time Gaming (BTG) patented the Megaways mechanic in 2016, few could have predicted how profoundly it would alter the online slots landscape. Today, Megaways titles are among the most played slots in the world, and the engine has been licensed to dozens of major software providers. Understanding how it works helps you know what you're playing — and why the potential payouts are so significant.

What Exactly Is the Megaways Engine?

Traditional slots have a fixed number of symbols per reel and a fixed number of paylines. A classic 5-reel, 20-payline slot always gives you 20 ways to win per spin, regardless of what lands.

Megaways works differently. On each spin, the number of symbols displayed on each reel is randomly generated — typically between 2 and 7 symbols per reel. This creates a different number of "ways to win" on every spin. The formula is simple:

Ways to Win = (symbols on reel 1) × (symbols on reel 2) × ... × (symbols on reel 6)

With six reels showing 7 symbols each: 7 × 7 × 7 × 7 × 7 × 7 = 117,649 ways to win. That's the maximum for most Megaways games — and it changes every single spin.

The Cascade / Tumble Mechanic

Almost all Megaways games pair the engine with a cascade mechanic (also called Tumble or Avalanche). When a winning combination lands, the winning symbols are removed and new ones fall into their place — potentially creating chain reactions of consecutive wins from a single spin. This mechanic is key to Megaways' big-win potential, especially when combined with a rising multiplier.

Why Megaways Games Tend to Be High Volatility

The massive range of ways to win (from as few as 64 up to 117,649) means most spins land at the lower end of the ways count. The huge payouts come when:

  • Maximum ways are active
  • Multiple cascades occur in sequence
  • An active multiplier amplifies a large cascade win

This combination of low-frequency, high-impact wins is the definition of high volatility — exciting, but requiring a proportionally sized bankroll to weather the variance.

Notable Megaways Titles That Defined the Format

  • Bonanza Megaways (BTG) — The original flagship title; still widely regarded as one of the best
  • Extra Chilli Megaways (BTG) — Gamble feature on free spins adds a unique twist
  • Gonzo's Quest Megaways (NetEnt/Red Tiger) — Classic theme reimagined with the engine
  • Primal Megaways (Blueprint) — Nature-themed with strong bonus potential
  • Reel King Megaways (Red Tiger) — UK classic brought into the Megaways era

The Licensing Boom and Industry Impact

Big Time Gaming made a strategically significant decision to license the Megaways patent to other providers rather than keep it exclusive. This decision led to a wave of Megaways titles from providers including Pragmatic Play, Blueprint, Red Tiger, iSoftBet, and Relax Gaming — each adding their own creative spin to the core mechanic.

The result was arguably the biggest shift in slot design since the move from physical reels to video slots. Regulators have since paid closer attention to Megaways games due to their high max-win potential, and some jurisdictions have introduced restrictions on maximum win multipliers or minimum RTP floors specifically in response to the format's popularity.

Is Megaways Right for You?

If you enjoy high-volatility games with big bonus potential and satisfying cascade mechanics, Megaways slots are worth exploring. If you prefer steady, frequent wins and longer sessions on a smaller budget, lower-volatility non-Megaways alternatives may suit you better. The key is matching the game's characteristics to your own playing style and bankroll.
