What is Megaways?
Megaways is a slot machine payout mechanic that was first launched by Australian casino game developer Big Time Gaming (BTG) in 2016. In Megaways slots the number of symbols on each reel changes every spin. This means the number of possible winning combinations can shift from spin to spin-sometimes just a few hundred, other times over 100,000. More symbols = more possible ways to win.
You still win by landing matching symbols on consecutive reels, from left to right. What makes Megaways exciting is the constant change with every spin of the reels.
Most Megaways titles add cascading wins (winning symbols disappear, new ones drop in), multipliers that climb during bonus rounds, and the odd reel modifier (mystery symbols, expanding reels, extra symbols from the top). The result is a fast, varied style of play.
Megaways slots don’t have fixed paylines. Instead, they use a game engine where the number of symbols per reel changes with every spin, which means the number of possible winning combinations (or ‘ways to win’) changes too.
Rather than playing on a traditional 5×3 grid with, say, 10 or 20 paylines, Megaways slots typically have 6 reels and anywhere from 2–7 symbols landing on each spin. The changing number of symbols could give you 324 ways on one spin, over 10,000 the next, and up to 117,649 ways or more, depending on the title.
Example: Big Bass Bonanza vs Big Bass Bonanza Megaways
| Version | Reels & Layout | Paylines/Ways | Features |
| Big Bass Bonanza (Original) | 5 reels × 3 rows | 10 fixed paylines | Wilds, Free Spins with Fish Values, Collector Mechanic |
| Big Bass Bonanza Megaways | 6 reels with changing height (up to 7 symbols per reel) | Up to 46,656 ways to win | Cascading Wins, Random Reel Modifiers, Free Spins with Fish Collector, Exploding Fish Multipliers |
The difference in play:
- In the original version, every spin uses the same static layout – easy to follow, but predictable.
- In the Megaways version, the reel heights vary on every spin. For example, Reel 1 might show 4 symbols, Reel 2 might show 6, and so on – this changes the number of ways to win constantly.
- It also adds cascading wins, where winning symbols explode and let new ones drop in-ideal for longer win chains (from only a single wager).
The bonus round is juiced up too: land enough fish symbols and collectors, and you’ll unlock win multipliers and retriggers faster than in the original.
