The Bonanza Slot game is one of Big Time Gaming’s biggest hits, and it’s not difficult to see why. With 117,649 ways to win and an RTP of 96%, it’s going down as one of the classic slot games.

In the past, slots ruled Vegas supreme. Sure, you might have seen blackjack and poker tables in Hollywood flicks, but for the general population, slots and jackpots were the name of the game. And that shouldn’t be surprising. They were simple to play and offered fantastic rewards worth no more than a few minimum bet spins. That kind of popularity didn’t fade away once slots came online. Many developers tried to replicate the success of vintage slots, and thanks to the Bonanza slot game, that genre lives on.

The slot was developed and released by Big Time Gaming, one of the big time names on the slot market. Available for free and real money, Bonanza blended vintage gameplay with the possibility of huge wins. It also introduced the Megaways mechanic to the market. While it’s not the first slot that uses it, Bonanza put RTG’s popular mechanic on the map.

The Bonanza slot online comes with 117,649 ways to win and an RTP of 96%. It’s a game of high variance and as mentioned earlier, it features the Megaways mechanic. For those unaware, this is a game-changing slot mechanic that enhanced slot gameplay and boosted the rewards. It’s safe to say that it changed the industry from its core, being used in many slots later.

Of course, it wouldn’t be as popular as it is today if it wasn’t for the Bonanza slot machine. The BTG hit was released in 2016 and paved the way for bigger Megaways adoption. By blending old-school gameplay with huge and modern features, Bonanza did something not many other slots could to.

Visuals, Setup, and Paytable

We’d be lying if we said that Bonanza is a top-shelf slot in terms of visuals. As a matter of fact, it looks a bit archaic, even with the 3D graphics. Just like all other Megaways slots, it comes with an unorthodox setup that we can explain as 7x7x7x7x7x7. It has 7 reels with a varying number of rows, so you can land plenty of symbols on it.

That shouldn’t stop you to play Bonanza just like any regular game. It’s still an online slot at its core, and the mechanics are simple enough to make the gameplay simple. The Bonanza game is packed with features, but when it comes to the layout and design, things are simple. And we wouldn’t make it any other way.

Thanks to the hillbilly sound effects, this is a slot that will fully immerse you into the fantastic atmosphere. This is a mining-themed slot bonanza. The reels are set against a mine which ties in perfectly into the theme. The top row features mine carts filled with diamonds that can spice your wins up. The 4 symbols carried on the cat will raise your winning chances. If you don’t know how that works, you should try the Bonanza slot demo. It’s free to play in most BTG casinos and will give you an overview of all the features.

In terms of payouts, the diamonds pay the most as expected. You get paid 50x your stake for five diamonds on the line, with the blue and red gems paying 7.5x and 2x the bet respectively for the same combination. Every cart adds a symbol on the reels if it lands above reels 2, 3, 4, and 5.

It’s all about reactions in the Bonanza game online, which is part of the Megaways mechanic.

Bonanza Slot on Mobile Devices

The Bonanza slot machine is available on PC, laptop, mobile, and tablets. Unlike the fans, it doesn’t discriminate when it comes to mobile OS choices. It runs great on Android phones and iPhones and iPads too. No need to download anything to play Bonanza. Just fire up your favorite casino via your top browser and play it right away.

And no, you don’t need the latest smartphone. Any phone from the past 4-5 years will do nicely.

How Does the Bonanza Online Slot Work?

Before you start playing the game, you should set your bet. The stakes go from $0.20 to $20 per spin. That might look pretty low and uninspiring for some players, but keep in mind that this is a Megaways slot game. Not many slot games give you 117,649 ways to win.

With that being said, you must understand that this is not your typical slot. The Bonanza slot free play game comes with ways to win instead of paylines. Each reel on its own or with a cart can have up to 7 symbols which influence the chances to win. The maximum number is 117,649 ways to win, which is more than what your grandma’s slot in Vegas offers.

Wins are awarded left to right for adjacent symbols regardless of their size. You can see the number of Megaways in play on each spin displayed right over the reels.

Let’s take a look at some of the features available in the Bonanza slot online.


The main highlight of the Bonanza slot game is the Megaways mechanic. Developer by Big Time Gaming itself, it’s a unique feature that applies on each spin. To put it simply, every time you play Bonanza, the number of ways to win varies on each spin. That’s pretty different from having, say, 20 fixed paylines.

The core feature of the Megaways mechanic are avalanche wins. This feature is called differently depending on the slot. In the Bonanza game online, they’re called Reactions.

Every time you hit a winning combination the Reactions feature comes into play. Every winning symbol will be blown to bits on the reels and replaced by a new one. New symbols may spell new winning combinations, leading to bigger wins. The wins can and will go on as long as new win combos are formed in the Bonanza slot game.


Look at the top of the reels when you play Bonanza – there should be mining carts attached. These carry 4 different symbols that can step in to complete winning combinations on reels 2-5. The carts are an important feature of the Megaways mechanic and can spice up your non-winning spins nicely.

Right above the carts are the Megaways to win. Whenever a cart symbol lands on the reels, they will increase. Think of the carts as your gift on each spin. Even if there’s a symbol missing for a win combo, the cart can provide it which will start an avalanche that can lead to bigger and better wins.

Bonanza Free Spins and Bonus Features

The free spins round in the Bonanza game online comes with an unlimited multiplier. It isn’t traditionally triggered with 3 or more scatters. Well, scatters are used, but in order to get to the bonus round, the gold scatters need to spell GOLD. You get 12 free games to start with, with each extra scatter adding 5 extra to your tally.

The win multiplier in the bonus round starts at x1. It goes up by +1 with each reaction win, and the number doesn’t reset on losing reactions. During the bonus round, scatters can only appear in the carts. For each 3 scatters you get 5 extra spins, while 4 bring you 10. There’s no limit on the number of free games you can win.

While the free spins round in the Bonanza game doesn’t reinvent the wheel, it does improve the slot’s winning potential. All the other features are active in the bonus round, and thanks to avalanche wins, this is where you can hit the big prizes. With a bit of luck, the main reward is 10,000x your bet.

Bonanza RTP and Technical Data

The Bonanza free slots game has an RTP of 96%. That’s right around the industry average for highly average slots. We’re a bit disappointed it didn’t go higher, but at least it’s not under 96%.

With the average being mentioned, we must say that this isn’t a slot you should mess with. If you don’t keep an eye on your bankroll, you could be bankrupt pretty soon. The Megaways mechanic is rewarding, but if you max your bets out right from the beginning, you can’t expect to hit big wins – you won’t have the bankroll to get to one.

Technically, the hit rate is lesser than expected if you don’t count on the reactions. Still, with a bit of luck, the Bonanza slot online can be pretty lucrative.

Bonanza Slot Conclusion

Bonanza is one of the all-time slot greats. It’s a mining-themed slot that introduced the Megaways gameplay mechanic to the crowd. While there are bigger Megaways-themed slot games, this is the one that beats them all.

Why? Well, for one, it blends old-school gameplay with modern features properly. It’s a highly volatile slot with plenty of surprises starting with the reactions. These can go on and on until there are no winning combinations, which can be pretty rewarding in both the base game and free spins round.

On the other hand, the slot has a few extra features that can deliver even bigger payouts. On top of it all, it’s plenty of fun. Whether you play the Bonanza slot free play mode or you spin for real money, you’ll have fun with it, and that’s all that matters.
