My review of Bonanza Megaways

My experience

Playing Bonanza in 2026 feels a bit like watching the first film in a franchise after seeing all the sequels — and realising the original still holds up. The presentation is dated next to modern Megaways slots, but the core loop is timeless. Each spin, the six reels rattle to a different height and a little mine cart trundles across the top, dropping extra symbols onto the four central reels. Watching the ways-to-win counter spike toward 117,649 when the reels run tall never gets old.

The base game, I'll be honest, is where this slot tests your patience. It's High volatility, and most of the return is locked behind the bonus. Reactions keep it lively — a winning combination blows up, fresh symbols tumble in from above and slide in from the right, and you can chain two or three wins from a single bet — but full-screen base-game hits are rare. In my sessions I spent a lot of spins hunting the four gold letters that spell G-O-L-D.

When GOLD finally lands, the game comes alive. The free spins open with 12 spins, but the number on the counter matters far less than the multiplier sitting beside it. It starts at 1x and ticks up by one with every single Reaction — and crucially, it never resets and has no cap for the duration of the round. So the dream isn't a single huge symbol combination; it's a long, snaking cascade that drags the multiplier up to 10x, 20x, 30x before a decent win lands on top. That's the math that makes the 26,000x ceiling possible, and it's why a quiet-looking bonus can suddenly detonate on the last few Reactions.

My honest take after many hours: Bonanza is a slow burn that rewards discipline. The base game will not carry you, so you have to respect the variance and play for the bonus without chasing it. I played most sessions at the lower end of the bet range and treated every free spins trigger as a bonus, not an expectation. It's a piece of slots history that's genuinely still fun — but it guarantees nothing, and a cold run can last a long time.

Who is Bonanza Megaways for?

Bonanza is for anyone who wants to play the slot that invented the Megaways genre, and for players who enjoy cascade-and-multiplier mechanics where the bonus is the whole point. If you like the building-multiplier tension of games such as Jammin' Jars 2 or the cascade chains in Razor Shark (both reviewed here), Bonanza is the granddad of that whole idea and will feel familiar. It suits patient players who accept long base-game droughts in exchange for an explosive free-spins ceiling. It's less suited to players who want frequent small wins for their money — for a gentler ride, my reviews of Big Bass Bonanza and The Dog House cover lower-variance options. Whoever you are: set a budget before you spin, never chase losses, and remember the house edge of roughly 4% applies to every single spin.

How Bonanza Megaways works

At its core, Bonanza is a Megaways slot with Reactions (cascading reels). It runs on 6 main reels, each of which can independently show between 2 and 7 symbols on any given spin, plus a horizontal cart reel that feeds extra symbols onto the four central reels. Because the symbol heights change every spin, the number of ways to win is recalculated each time, ranging up to a maximum of 117,649 — matching symbols on consecutive reels from the leftmost reel pay, with no fixed paylines. Wins trigger Reactions: the winning symbols vanish and are replaced by new ones dropping from above and sliding in from the right, potentially chaining further wins from one bet. The bonus is built around the gold-letter scatters that spell G-O-L-D and an unlimited free-spins multiplier. Here is every mechanic, one by one.

Where to play Bonanza Megaways

Bonanza is a piece of slots history that's still genuinely worth playing. As the game that invented the Megaways mechanic, it earns its place on any shortlist, and the core loop — shifting reels up to 117,649 ways, cascading Reactions, a mine cart feeding extra symbols and Wilds — remains satisfying nearly a decade on. The free-spins multiplier, which starts at 1x and climbs uncapped with every Reaction, is the feature everyone else copied, and it's still the most exciting thing about the game. But let me be clear: this is a High-volatility slot whose base game can run cold for long stretches, with most of the return locked behind a bonus that doesn't trigger often. Most sessions will end in the red — that's what a roughly 4% house edge plus High variance means in practice. Play a demo at a licensed casino first, size your bets like a professional, set a budget, and treat any big bonus as the exception, never the plan. 8.5/10: the original Megaways slot, still fun, still worthy of respect — and still demanding discipline. 18+, play responsibly.
