What Are Megaways Slots?

Megaways slots feature a dynamic reel configuration that changes with every spin, offering hundreds or even thousands of ways to win.

Since Big Time Gaming revolutionised the industry in 2016 with its hit release Bonanza, the innovative Megaways mechanic has dominated the market, with dozens of providers licensing the technology to expand its impressive collection of slots.

How Do Megaways Slots Work?

The Megaways reel mechanism randomly changes the number of symbols on each reel.

Megaways slots typically feature 6 reels, each displaying 2 to 7 symbols. More symbols per reel mean more paylines per spin, starting from 64 and reaching up to an impressive 117,649 at maximum capacity—though some exceptions exist, so always check your chosen game.

Alongside pioneer Big Time Gaming, several other slot studios now use the Megaways engine, continually innovating to deliver fresh experiences for players.

Some push the boundaries of the standard format, such as Iron Dog Studio with 1 Million Megaways BC, which lives up to its name by offering an incredible 1,058,841 ways to win.
