If you’ve browsed an online casino lobby recently, you’ve seen the word everywhere — Bonanza Megaways, Gonzo’s Quest Megaways, Eye of Horus Megaways. Megaways is one of the most successful slot mechanics ever created, and it fundamentally changes how a spin feels. This guide explains what Megaways slots are, how the engine works, and what to know before you play.
What Does “Megaways” Mean?
Megaways is a slot mechanic invented by Australian studio Big Time Gaming (BTG) and introduced in 2016 with Dragon Born, though it was Bonanza Megaways later that year that took the format worldwide. The defining feature is a variable reel mechanic: instead of each reel showing a fixed number of symbols, Megaways reels randomly display between two and seven symbols on every single spin. Because the layout changes each time, so does the number of ways to win.
How the Ways-to-Win Are Calculated
Megaways games typically use six reels. The number of ways to win is found by multiplying the number of symbols showing on each reel together. When all six reels show the maximum seven symbols, you get 7 × 7 × 7 × 7 × 7 × 7 = 117,649 ways to win — the number you’ll see quoted most often. As the technology has advanced, some titles now exceed 200,000 ways, and a few push past a million.
Wins are awarded differently from classic paylines. You don’t need symbols in a fixed line — you win by landing matching symbols on adjacent reels, starting from the leftmost reel, regardless of which row they sit on. Usually three or more matching symbols on consecutive reels pays.
Megaways vs Traditional Slots
| Feature | Classic slot | Megaways slot |
|---|---|---|
| Reel layout | Fixed symbols per reel | 2–7 symbols, changes each spin |
| Ways to win | Fixed paylines (e.g. 20–243) | Variable, up to 117,649+ |
| Volatility | Low to medium common | Usually high |
| Signature feature | — | Cascading reels |
The Signature Features
Most Megaways games pair the variable reel engine with several features that define the experience:
- Cascading (avalanche) reels: when you land a win, the winning symbols are removed and new ones drop in to fill the gaps. If those form another win, the process repeats — so a single spin can produce a chain of consecutive wins.
- Increasing multipliers: in many free-spins rounds, each cascade bumps a win multiplier higher, which is where the biggest payouts usually come from.
- Free spins and retriggers: scatter-triggered bonus rounds, often with an unlimited multiplier that carries through the feature.
- Mystery and expanding symbols: extra layers that can transform reels and boost win potential.
Volatility: What to Expect
Megaways slots are almost always high-volatility games. That means wins can be infrequent, but when they arrive — particularly during a bonus round with a rising multiplier — they can be substantial. On average a bonus feature might trigger only every few hundred spins, so your bankroll needs to be sized to survive the dry spells. If you’re new to the idea of risk levels, our guide on how slot volatility affects your wins is worth reading first. Most Megaways titles sit in a 96%–97% RTP range, though this varies by game and operator version.
Who Makes Megaways Slots?
BTG originated the mechanic and now licenses it to many studios. Prolific Megaways developers include Blueprint Gaming (Fishin’ Frenzy Megaways, Buffalo Rising Megaways), Pragmatic Play (Big Bass Bonanza Megaways, Great Rhino Megaways), NetEnt (Gonzo’s Quest Megaways), and Red Tiger. Many of the most popular Megaways titles are Megaways versions of already-successful classic slots.
How to Play a Megaways Slot
- Set your stake using the plus/minus controls — there are no separate paylines to activate.
- Spin; watch the reels stop at a random height, revealing that spin’s number of ways to win.
- Matching symbols on adjacent reels from the left pay out.
- Cascading reels then clear winners and drop new symbols in — potentially chaining more wins.
- Land the scatters to trigger the free-spins feature, where the biggest wins usually live.
Are They Worth Playing?
Megaways slots are prized for their unpredictability — no two spins look the same, and the cascading engine keeps a single bet alive far longer than a classic slot. The catch is the higher volatility, so they suit players who enjoy swings and have the patience (and budget) to wait for the bonus rounds.

The Bottom Line
Megaways slots replace fixed paylines with a reel engine that randomises the number of symbols — and therefore the ways to win — on every spin, commonly up to 117,649. Add cascading reels and rising multipliers, and you get a dynamic, high-volatility game with serious top-end potential. Understand the volatility, set a budget, and enjoy the fact that every spin is genuinely different.
