If you’ve ever wondered what it’s like to dig for treasure while listening to banjos and existential despair, then Bonanza by Big Time Gaming is your golden ticket to self-inflicted misery. This is the slot that launched the Megaways slot empire, a format that makes you feel like you’re winning something when, in fact, you’re not. With up to 117,649 ways to win, Bonanza gives you all the illusion of hope with none of the substance.
But hey, it’s still one of the most played online slots of all time in top casinos, mostly by people who don’t realize they’ve aged five years since they started spinning. You can try the free demo right now at Casinos.com, or read on to discover if this game really is the mother lode, or just another hole in the ground.


I’m Goldislots, vault whisperer, porridge taster, and part-time prospector of pixelated gold. My compass led me here, to the rattle and rumble of Bonanza, where the hills hum and the reels promise fortunes buried just below the spin.
The Bonanza slot plays on 6 reels with anywhere between 2 and 7 symbols dropping onto each one, thanks to the Megaways mechanic. This gives you between 64 and 117,649 ways to win, which sounds impressive until you realize most of them pay less than the cost of your spin.
You can bet between $0.20 and $500 per spin, which is great news if you enjoy financial ruin at different speeds. The game’s RTP sits at 96%, and it’s high volatility, meaning you’ll spend most of your session waiting for one big win, like a miner praying the next stick of dynamite doesn’t blow off both his hands.
Wins are formed by landing matching symbols on adjacent reels from left to right. The highest-paying symbol is the white diamond, worth 50x your stake for six in a row. So, if you’re betting the max at $500, you’re looking at a potential jackpot of $5,000,000. Sure, it could happen, but so could a talking canary offering you life advice.
There’s no bonus buy here, because Big Time Gaming released Bonanza before developers realized people are happy to skip foreplay and go straight to the good stuff.
Every time you hit a win, the symbols explode, vanish, and are replaced by new ones dropping down from above. It’s called the Reactions feature, but “emotional manipulation” feels more accurate. It can trigger back-to-back wins until the game decides you’ve had enough fun.
Bonanza is the game equivalent of finding fool’s gold, shiny, exciting, and ultimately worthless. The Megaways mechanic is clever, the cascading wins are satisfying, and the free spins can deliver serious payouts… sometimes. But the theme, the sound effects, and the sheer repetition make this feel more like work than play.
Still, it’s an industry-defining slot, and for that, it deserves a respectful nod before being buried in a shallow grave. If you’ve never tried it, play the free demo at Casinos.com before you start digging into your real money stash at top slot sites.
Once upon a spin, deep in the mountain’s mechanical heart, I found Bonanza, a mine that hums promises it can’t quite keep. I set my stake at $2 a spin, brushed the dust off my compass, and descended where fortune echoes louder than reason.
The reels are carved into stone, each spin a clink of pickaxes in the dark. A miner’s hut winks from the cliffside, a waterwheel turns for no purpose but cheer, and a cart trundles by to spill more glitter into the abyss. The banjo soundtrack twangs too brightly, like a grin that’s practiced in the mirror, all charm, no soul.
Forty spins later, I was muttering the miner’s mantra: just one more go. When the Free Spins cave opened, I thought I’d struck honeyed gold. The multiplier climbed like a rope to daylight, and then snapped. My treasure? Fourteen dollars. Enough to buy the coffee I’ll sip while writing this lament.
Would I return? Of course. The curse of every miner is hope, that the next swing, the next spin, might finally sing the right note in the rock.

Yes, there are. Land the letters G, O, L, D across the reels to trigger 12 free spins, complete with an increasing multiplier for each cascading win. It’s the slot equivalent of an adrenaline rush, followed immediately by crippling disappointment when your multiplier hits 20x and you win absolutely nothing.
The maximum payout in Bonanza is 10,000x your stake, which translates to a potential $5,000,000 if you’re mad enough to play at the max bet. Sure, you’ll probably never see it, but the fantasy is half the fun, right before reality hands you a pickaxe and says, “Keep digging.”
The Bonanza slot was released by Big Time Gaming in December 2016. It didn’t just drop into the market; it blasted its way in with dynamite, redefining online slots with its revolutionary Megaways mechanic. Nearly a decade later, it’s still one of the most played and most imitated games in existence.
