Bonanza Megaways

Bonanza Megaways by Big Time Gaming is the slot that introduced the world to the Megaways engine, with up to 117,649 ways to win. A mining-and-gems theme, cascading reels and an unlimited win multiplier in free spins made it an instant classic and the blueprint for thousands of imitators.

This review explains how Bonanza works, the Megaways and unlimited-multiplier mechanics, the RTP, and how to play it.

What is Bonanza Megaways?

Bonanza is a 6-reel Megaways slot where the number of symbols per reel changes every spin, varying the ways to win up to 117,649. A horizontal reel adds extra symbols on top. Winning symbols explode and new ones cascade in, and in the free spins an unlimited win multiplier rises by 1x with every cascade.

That unlimited, ever-increasing free-spins multiplier is the key to Bonanza’s biggest wins and a mechanic that defined the Megaways genre. For more, see our Megaways slots explained guide.
