Slots Like Bonanza: Similar Megaways Games, RTP and Our Verdict
Looking for slots like Bonanza? Start with Extra Chilli for another Big Time Gaming Megaways game with an unlimited free-spins multiplier, White Rabbit for expanding reels and cascading wins, or Diamond Mine for a mining-themed Megaways alternative. Bonanza itself uses up to 117,649 ways to win, Reactive Reels and the GOLD free-spins trigger. Big Time Gaming’s current product page states a 96.11% RTP and a maximum payout of 26,000× stake.
Released in December 2016, Bonanza wasn’t the first Megaways slot. That was Big Time Gaming’s own Dragon Born, earlier the same year. But it was Bonanza that turned the mechanic into a format the whole industry copied. The slow G-O-L-D build-up on the mine cart reel, a multiplier with no ceiling, and a launch that landed just as slot streaming took off all came together at once, and the game became the most talked-about UK online slot since Starburst. Nearly ten years on it’s still the one most people mean when they go hunting for games like Bonanza.

Bonanza runs on six main reels, and here’s the twist that made it famous: each reel shows anywhere from two to seven symbols on any given spin, so the grid is never the same shape twice. Above reels two to five sits a horizontal mine cart reel that adds four more symbol positions. Put it all together and you get up to 117,649 ways to win, which is where the Megaways name comes from. Wins land left to right on adjacent reels, in any position, so you’re matching symbols rather than chasing fixed lines.
Every win sets off a Reaction. The winning symbols blow up, fresh ones drop in from the dynamite chute above, and it keeps going for free until a drop lands no new win. In the base game that’s a tidy way to string a couple of hits together. In free spins it’s the whole point, because each Reaction also nudges the multiplier up. Stakes run from 20p to £20 a spin, so it’s reachable for low rollers but capped fairly low at the top end.
Symbols and Paytable
The low pays are mining-stamped playing-card values from nine up to Ace, sitting on little stone blocks. The premiums are four cut gems, and the purple one is the big earner. On its own the top symbol is modest, the purple gem pays around 50 coins for a six-of-a-kind and six Aces return just 1.75 coins, so a single combo rarely feels life changing. The maths only really sings when several ways pay at once and the Reactions chain together. The dynamite Wild turns up on the cart reel and stands in for everything except the GOLD scatters.
Pros and Cons
Pros
- The free spins multiplier has no ceiling. It opens at 1x and adds 1x on every Reaction, so it’s a long chain of cascades, not one lucky symbol, that produces the headline wins.
- The G-O-L-D trigger is properly tense. Watching the letters drop onto the cart reel one at a time, needing all four, is one of the most recognisable build-ups in any UK slot.
- Extra GOLD scatters landing during the bonus add five more spins each and don’t reset the multiplier, so a retrigger late in a hot run can be enormous.
- You get the full 117,649-way engine from just 20p a spin, which is rare for a game with this kind of top-end potential.
Cons
- The base game can be a long, quiet wait. Dead spins are common and the bonus is hard to hit, a gripe you’ll see again and again in the player reviews further down this page.
- The £20 max bet shuts out high rollers. Even on the revised 26,000x model, full stake tops out at £520,000, modest next to newer high-variance titles.
- The G-O-L-D near miss, three letters landing without the D, happens often enough to sting, and it’s the single most cited frustration with the game.
- There’s no bonus buy for UK players, so when the feature won’t come, there’s no shortcut to it.
Bonus Features Explained
The GOLD Free Spins Trigger
Free spins are the heart of the game. You need the letters G, O, L and D to land together on the horizontal cart reel above reels two to five, and all four gets you 12 free spins to start. It isn’t easy, and that scarcity is the design, since almost all of the win potential lives inside the feature rather than the base game.
The Unlimited Multiplier and Reactions
Once the feature starts, the multiplier kicks in at 1x and climbs by 1x with every winning Reaction. It doesn’t drop back between spins inside the same bonus, it only resets when the feature ends, so the dream run is win, cascade, win, cascade, with the multiplier ticking up the whole time. That compounding is how people land the four-figure-times-stake clips you’ll find on the streaming sites, and it’s why a 12-spin bonus that keeps reacting can outrun a longer one that goes cold.
Closely Related Games
Bonanza has 4 closely related games including Diamond Mine Bonanza 2, Dynamite Digger and Dynamite Riches.
- DIAMOND MINE
Diamond Mine is Blueprint’s mining Megaways slot, and it’s the closest theme-and-mechanic match to Bonanza on this list. Same 117,649-way engine, same gold-dust setting, with a free spins multiplier of its own. - BONANZA 2
Bonanza 2 is the official follow-up. You get the same gold-mine setting and cascading Reactions, with a reworked feature, so it’s the obvious next stop once you’ve had your fill of the original. - DYNAMITE DIGGER
Dynamite Digger shares the mining theme and the exploding, cascading reels, but at lower volatility. Wins land more often and smaller, which suits players who find Bonanza’s dry spells hard going.To win, you dig. - DYNAMITE RICHES
Dynamite Riches keeps the mining setting with golden and colossal symbols and random wilds. It’s a steadier, more affordable alternative for sessions when Bonanza won’t hand over the bonus.
Similar Games by Theme
Bonanza is a gold-mining slot, and the theme matters here because the best alternatives tend to share both the setting and the cascade-led maths. If you like games similar to Bonanza, mining titles are the natural place to start.
More Mining themed slots to try
Mining slots dress the reels up as a dig for gems and gold, and the good ones use that theme to justify a feature you have to work toward, which is exactly what Bonanza does with its buried free spins round. Lost Island, Dynamite Digger, Dynamite Riches, Bonanza 2 and All My Gold all sit in the same theme if you want to stay in the mine.
A few of these, like Diamond Mine and Diamond Mine Extra Gold, also run the Megaways engine, so they come closest to recreating the actual feel of Bonanza rather than just the look.
Diamond Mine
Diamond Mine has 117649 paylines with 6 reels and NA rows and a 96.43% RTP.
Diamond Mine Extra Gold game
Diamond Mine Extra Gold comes with 117649 pay lines with 6 reels and 7 rows and a 94.13% RTP which is Medium-Low. Diamond Mine Extra Gold is developed by Blueprint and has Medium volatility.
Treasure Mine game
Treasure Mine comes with 40 pay lines with 5 reels and 4 rows and a 95.20% RTP which is Medium. Treasure Mine is developed by Red Tiger Gaming and has Low volatility.
Dwarf Mine slot
Dwarf Mine slot is a Dwarf themed game with 4 rows and 5 reels with a 96.80% RTP.
All My Gold
All My Gold keeps the pit-head setting but swaps cascades for ReelPlay’s Locked Reels, running 4096 ways on a 6 reel, 4 row grid with a 96.04% RTP. Six or more GOLD NUGGET symbols start Bonus Respins where every nugget holds its own multiplier of up to 1000x, so the gold collect does the heavy lifting that Bonanza hands to its unlimited multiplier.
More Slots from Big Time Gaming
Big Time Gaming was founded in Sydney in 2011 and built its name on a single idea: the Megaways reel system, which it still licenses to studios like Blueprint and Pragmatic Play. Evolution bought the studio in April 2021, and it holds a UK Gambling Commission licence to operate here. Bonanza is the game that made all of it happen, the breakthrough hit that took BTG from a small Australian outfit to one of the most influential names in slots, alongside later flagships Extra Chilli and White Rabbit.
If you want more from the same studio, these are all Big Time Gaming titles. Holy Diver in particular shares Bonanza’s high-variance, multiplier-led approach.

Frequently Asked Questions
How do you trigger the free spins in Bonanza?
Land the four GOLD letters together on the horizontal mine cart reel above reels two to five. That awards 12 free spins, and every extra GOLD scatter that drops during the bonus adds five more.
What is the multiplier in Bonanza and does it reset?
It starts at 1x when free spins begin and rises by 1x on every winning Reaction, with no upper limit. It holds across spins inside the same bonus and only resets when that feature ends.
What is the RTP and volatility of Bonanza?
Big Time Gaming’s current Bonanza product page states a 96.11% RTP. The game is high volatility, with most of its potential concentrated in the free-spins feature. Check the information screen before playing because an operator may offer a different configuration.
What is the maximum win on Bonanza?
Up to 26,000x your stake on the current revised model, which works out at £520,000 from the £20 max bet. The original release was capped at 12,000x and many slot databases still list that figure, so the ceiling depends on the build your casino is running.
Was Bonanza the first Megaways slot?
No. Big Time Gaming’s Dragon Born, released earlier in 2016, was the first. Bonanza arrived in December that year and was the one that made Megaways famous, helped by how well it played to streaming audiences.
What are the best slots like Bonanza?
For the same engine from the same studio, Extra Chilli adds a bonus buy and a gamble feature, and White Rabbit offers a higher RTP. From other studios, Razor Shark by Push Gaming gives you the same brutal cascade tension, while Primal Megaways and Diamond Mine by Blueprint pair the licensed Megaways engine with a mining theme close to Bonanza’s.
Can you play Bonanza for free?
Yes. A free demo runs on the developer’s site and at most casinos that carry the game, which is the easy way to get a feel for how often the bonus lands before you stake real money. Real-money play is for over-18s at UK-licensed casinos.
Our Verdict on Bonanza
Nearly a decade on, Bonanza still holds up, and I’d point most people who go looking for slots like Bonanza straight back to the original before any of its imitators. It’s a game for patient, high-variance players who enjoy the slow build and the payoff of a multiplier that won’t stop climbing. It is not for anyone who wants steady base-game action or a high staking ceiling. Want the same engine with a bonus buy? Extra Chilli is the natural next step. After a higher RTP? Try White Rabbit. And for the same cascade tension from a different studio, Razor Shark by Push Gaming is the closest thing going. The £20 cap and the dead spells are real, but the GOLD build-up and that uncapped multiplier are still the benchmark every Megaways slot gets measured against.
