What Is Bonanza?

Bonanza is Big Time Gaming’s cascade ways mining classic that helped define modern Megaways DNA: cascading wins, free spins with climbing multipliers, high volatility, a ~96.00% RTP band, and a 14,000× max-win class.

It is the landmark BTG title — not Pragmatic’s Bonanza-named tumble skins and not BGaming’s Bonanza Billion. Falls sequels sit beside it with different ceilings.

This review covers how cascade multipliers climb, when Falls / Falls Megaways is the sharper switch, and how to verify the cash RTP panel on Top 10 brands.

How Bonanza Works

  1. Winning symbols cascade away and new ones drop for chained evaluations on the ways reel set. One paid spin can connect several cascade steps.
  2. Free spins are the upside path where multipliers can climb across cascades. Exact scatter counts and retriggers sit in the paytable.
  3. The 14,000× ceiling is the listed class in our catalog — above Bonanza Falls’ 10,000×, below Falls Megaways’ 50,000×.
  4. High-vol droughts between strong free-spin sequences are normal. Confirm ~96.00% on the cash panel before you raise stakes.
