Bonanza Megaways — The Slot That Made Megaways Mainstream
Big Time Gaming's Bonanza arrived in 2016 and turned the Megaways engine (introduced a year earlier with Dragon Born) into the most-licensed slot mechanic of the decade. The 96.00% RTP, the 12,000x maximum win, and the relentless base game energy made Bonanza the gateway slot for the entire Megaways category.
How the Megaways Engine Works in Bonanza
Six reels, each independently displaying between 2 and 7 symbols on each spin. The number of ways to win is calculated by multiplying the symbols on each reel — at maximum (7 on every reel) the figure reaches 117,649 ways. Bonanza adds a horizontal "carriage" reel above reels 2 to 5 that contributes additional symbols, increasing the maximum.
Cascading Reels
Winning symbols disappear after paying out and new symbols fall in from above. Consecutive cascades on a single spin can produce multiple wins, and the carriage reel refreshes between cascades. The cascading mechanism is what produces Bonanza's biggest base game wins — strings of cascades can multiply a small initial hit into a substantial total.
Free Spins
Four or more "GOLD" scatter symbols (one letter per reel, spelling G-O-L-D) trigger 12 free spins. The unlimited win multiplier is the key feature of the bonus round — it starts at 1x and increases by 1 with every winning cascade, never resetting until the bonus ends. The biggest Bonanza wins come from extended cascade chains in late-bonus spins.
Volatility
High volatility. The bonus trigger rate is lower than Book of Dead, but the bonus round when triggered carries higher peak potential. Bankroll planning matters more here than on most non-Megaways slots — plan for long stretches between bonus triggers.

Bonanza Megaways is available at every operator in our top 10. The broadest Megaways library overall is at Casumo (145+ titles); see our Megaways slot sites comparison for the full picture.
