About the Game
Bonanza is a mining-themed video slot from Big Time Gaming, released in late 2016 as the title that first popularized the Megaways mechanic, the dynamic reel system now licensed across the industry and explained in more detail in our Megaways guide.
The game runs on 6 dynamic reels offering up to 117,649 ways to win on any given spin. It carries a 96% RTP and is rated medium-high volatility, with a maximum win of 12,000x the stake.
Bonus Features
Winning combinations trigger a cascade, clearing symbols and dropping new ones in for a chance at further wins on the same spin, all without an additional bet. Landing enough scatter symbols spelling out “G-O-L-D” triggers the free spins bonus.
Inside the bonus, an unlimited win multiplier starts at 1x and increases by 1 with every cascading win, a mechanic that was genuinely novel when Bonanza launched and has since become a standard feature across countless slots that followed it.
RTP, Volatility & Where to Play
At 96% RTP with medium-high volatility, Bonanza remains a benchmark reference point in slot design nearly a decade after release, largely because of how influential its Megaways and increasing-multiplier mechanics turned out to be.
Bonanza is available at most crypto casinos that carry Big Time Gaming content. A progressive jackpot version, Bonanza Megapays, offers the same core game with four linked jackpots layered on top.
