What Is Megaways?

If you've spent any time exploring online slots, you've almost certainly encountered the word "Megaways." It appears on hundreds of game titles and is often treated as a quality signal by players. But what does Megaways actually mean, and why has it become one of the most influential mechanics in modern slot design?

Megaways is a patented reel mechanic developed by Australian studio Big Time Gaming (BTG), first introduced in their 2016 release Dragon Born. The core innovation is a variable reel system that changes the number of symbols on each reel with every spin — dramatically expanding the number of possible winning combinations.

How Traditional Slots Work (For Context)

In a standard 5-reel, 3-row slot, each reel always shows exactly 3 symbols. The number of ways to win is fixed — typically determined by the number of active paylines (e.g., 20 or 25). Every spin presents the same structural grid.

How Megaways Changes This

In a Megaways game, each reel can display a variable number of symbols per spin — commonly between 2 and 7. The number of symbols shown on each reel is randomized every time you spin. Because all reel heights change independently, the total number of symbol positions changes with every single spin.

Megaways games typically operate on a "ways to win" model rather than fixed paylines. In this system, a win occurs when matching symbols appear on consecutive reels from left to right, in any row position. The number of ways to win is calculated by multiplying the number of symbols visible on each reel.

Example Calculation

If a 6-reel Megaways game shows the following symbol counts per reel on a given spin: 7 × 5 × 6 × 4 × 7 × 6, the number of ways to win that spin is:

7 × 5 × 6 × 4 × 7 × 6 = 35,280 ways to win

On the very next spin, those numbers could all be different, producing an entirely different ways-to-win count. The maximum in most Megaways games is 117,649 ways to win (7⁶).

The Cascading Reels Connection

Almost all Megaways games pair the variable reel mechanic with cascading (tumble) reels. When a winning combination lands, those symbols are removed and new ones fall into place. If the new symbols create another win, the cascade continues — all from one spin payment. This creates the potential for chain reactions that can generate multiple wins sequentially.

Why Megaways Games Are Typically High Volatility

The dynamic reel system, combined with cascading mechanics, means wins can vary enormously in size. Sessions can involve long stretches with no significant wins, followed by cascade chains that deliver outsized payouts. This high-volatility profile is a defining trait of the format and explains why Megaways games attract players who are specifically chasing big-win potential.

The Megaways License

Big Time Gaming licenses the Megaways engine to other studios, which is why you'll find Megaways games from a wide range of providers — Pragmatic Play, Red Tiger, Blueprint Gaming, and many others. While they all use the same core variable-reel system, each studio builds its own themes, features, and bonus structures on top of the mechanic.

Popular Megaways Titles to Know

  • Bonanza Megaways (Big Time Gaming) — the game that popularized the format
  • Extra Chilli Megaways (Big Time Gaming) — features a buy-bonus option
  • Power of Thor Megaways (Pragmatic Play) — Norse mythology theme with free spins multipliers
  • Gonzo's Quest Megaways (Red Tiger / NetEnt) — a classic title reimagined with the Megaways engine

Is Megaways Right for You?

Megaways games offer a genuinely different rhythm to traditional slots — more dynamic, more volatile, and with significantly higher maximum win potential. If you enjoy high-variance sessions where the reel layout itself shifts with every spin, the format delivers a compelling experience. If you prefer predictability and frequent smaller wins, lower-volatility alternatives may serve you better.

Understanding the mechanic before you play helps you set appropriate expectations — which is always the best starting point.
