Bonanza: The Slot That Started Megaways
Bonanza gets credit for launching the Megaways mechanic that dozens of later slots have since licensed, and the mining theme was almost secondary to the innovation underneath it.

Does Bonanza live up to the hype?
Big Time Gaming built the reels with a variable number of symbols per spin, so the number of ways to win shifts on every turn instead of staying fixed — up to 117,649 ways at the maximum reel height. That variability is the whole point of Megaways: no two spins offer quite the same odds, and a tall reel configuration can turn a modest bet into a wide field of winning combinations.
Wins cascade rather than simply paying out and resetting — cleared symbols make way for new ones to drop, and each new cascade can trigger further wins without spending another spin. Four or more scatter symbols award free spins with an unlimited multiplier trail that climbs with every consecutive win during the round, uncapped in a way many later Megaways titles chose not to copy.
RTP sits at 96.0% with high volatility, consistent with a mechanic built for wide variance rather than steady, predictable returns. Free spins offers tied to Bonanza specifically inherit that variance directly — the free spins bonus is where the uncapped multiplier does its work, so outcomes here range further than most standard slot bonuses.
Golden Star carries Bonanza in its Big Time Gaming selection, a reasonable starting point for anyone curious about where the Megaways format actually came from.
