Big Time Gaming's Bonanza online slot is a Megaways game that offers you plenty of opportunities to win big – over 100,000 winning ways. It is a popular game among online slots players around the world thanks to its unique format and fun bonus features.

Graphics and Theme

When you enter the game, you'll be whisked off to a beautiful woodland retreat. With green grass and a rocky environment, it's filled with flowers and character. There's a wood cabin to the side of the screen, and an animated water wheel running constantly.

The reels are set in stone. It's here where you get the impression of a mining-themed slot. You'll want to pick something up and break right through them, but unfortunately, you'll have to be patient and spin to win.

How To Play Bonanza Slot

Quick guide to help you get started:

  1. Click the list menu to check out the paytable and select your sound preferences
  2. Adjust your total bet using the < & > buttons
  3. If you want to Autoplay, click the button and select your number of spins, loss limit and single win limit.
  4. Fix a session budget, hit 'Play' and hope luck is on your side.

Upon first glance, Bonanza seems a pretty complex slot. After all, it has six reels rather than five, and there is a different number of symbols on the reels every spin. However, you'll be pleased to know that Bonanza is quite simple.

Each reel can show between 2 symbols and 7 symbols, and there's a set of small reels along the top of the screen. Since each reel shows a different number of symbols, the total number of winning ways varies with each spin.

This is how the Megaways mechanic works, and you'll see it in plenty of Big Time Gaming slots.

Betting Options

You can wager between 0.20 and 200 per spin, which is the perfect range for players with smaller and mid-sized budgets. High rollers, too, should be able to get their kicks as they'll get plenty of value for their bankrolls.


An autoplay function is available for up to 100 spins, and you can set a loss limit or single win limit along with it. There are no other controls in the game, however, such as settings for the volume or the reel speed.

Loss and Win Limits

When using the Autoplay function, you have the option to set a loss limit and a single win limit. It's a good idea to set a loss limit so that you don't deplete your bankroll too quickly. It's a great way to keep track of your spending and ensure that you're playing responsibly, as you can reevaluate after you've hit your loss limit.

Bonanza Slot Big Wins

To hit a winning combination while playing the slot Bonanza, you have to land three or more matching symbols on adjacent paylines. This differs from payline-based games, as if offers up more winning potential overall.

While you can land 50x for a single line win when you play Bonanza slot, the cascading reels and multipliers offer up even better-winning potential. As such, the maximum win that you could potentially land is worth 12000x your wager.

How to Land Free Spins

To trigger the free spins round in Bonanza, you have to land four symbols that spell out GOLD during the base game. You'll receive 12 free spins, and you can trigger 5 more with every additional scatter symbol that lands.

What makes this bonus special is the unlimited win multiplier. Whenever you hit a win, the multiplier will increase - and, there's no telling how high it will go!

You can also earn extra free spins:

  • 5 more free spins for 3 scatters
  • 10 more free spins for 4 scatters

When you combine the cascading wins with the unlimited multiplier and the potential to earn more free spins, Bonanza offers up a very impressive bonus round. However, it can be pretty difficult to trigger.

Bonanza Slot RTP and Volatility

Bonanza from Big Time Gaming has an RTP (return to player) of 96%. This payout percentage refers to the amount of money that players can, on average, expect to earn as prizes.

It is also known to be a high volatility slots game. This means that you'll be able to cash in on larger prizes as you spin the reels, but they'll come around pretty infrequently. It's the opposite to a low variance game that offers up more frequent, smaller wins.

Geared More Towards High Rollers

So, while the slot Bonanza has a great betting range for penny players, the actual gameplay is better suited for players with larger budgets.

This is because you'll experience fewer wins overall when playing a high volatility game like Bonanza – even if your overall profit at the end of your session is larger than it would be on a low to medium volatility slot.

In the times between your wins, there is the potential for you to deplete your bankroll if you hit a particularly cold streak. So, if you're a player with a smaller budget, remember to be smart about how you bet. It's wise to go for quantity in a game like this, spending less on your wagers so you can fit in more of them during your gaming session.

Does Bonanza Have a Progressive Jackpot?

In a feature-rich slot like Bonanza, you'd expect the game to offer players the chance to land progressive jackpot prizes. Unfortunately, there are no progressive payouts in this game - but, there is a Bonanza Megapays slot that picks up the slack.

In Bonanza Megapays, the only major difference between it and the remake is the addition of a progressive jackpot network. The jackpot prize round is triggered randomly and it's played out in a unique way. 

One symbol is selected to be the Megapays symbol on the bonus reel set. The number of Megapays symbols that land will determine which jackpot you win.

The progressive jackpots in Bonanza Megapays seed at:

  • Mini Jackpot: €100
  • Midi Jackpot: €1500
  • Major Jackpot: €20,000
  • Mega Jackpot: €300,000

Impressive Maths Model

Normally, progressive jackpot slots have RTPs that are much, much lower than the industry standard. Take Mega Moolah, for example - it's one of the most popular progressive slots out there but only has a payout percentage of 88%.

Bonanza Megapays, on the other hand, has a payout percentage that is higher than the original's at 96.4%. This is pretty unusual in the online slots world, and we're thrilled that Big Time Gaming has chosen to go in this direction. 

Bonanza Slot Free Play

Before you get playing this online slot, it's always advised that you give the Bonanza free play demo a spin first. This is so that you can get a proper feel for the game without having to worry about spending any money if you don't happen to get on with it.

We always advise playing between 150 and 200 rounds for free before you decide to make a real-money wager on any slot. Your play-money wager must be similar to what it would be if you were playing with actual cash so that you get a good idea of whether or not it will fit within your budget.

If You Enjoy Bonanza, You'll Love...

Bonanza is a great online slot, but we understand if you want to give something a little bit different a spin.

Overall Review

Big Time Gaming's Bonanza is filled with adventure from start to finish. The concept is unique and entertaining, and the music gives the game a light-hearted feel. Your adrenaline will be racing as you spin the reels, and there's a lot of opportunity for winning combinations.

General Gameplay

There's a reason why Bonanza has prevailed as one of the most popular Megaways games of all time. Even as dozens of new Megaways slots are released, Bonanza maintains its position at the top of most slot fans' to-play list.

This is because Bonanza originated all of the features that players have come to associate with Megaways slots. The cascading reels paired with free spins that feature increasing multipliers set the standard. Even though there are now dozens of slots that come with this same format, most players prefer the original.

Bonanza Slot Base Game

The graphics look real, and it takes you to a charming place with the animations being a bonus we welcome. The underground feature is the best by far. You'll love watching the mines blow up and want to play over and over. The makers have surpassed our expectations with this one, and you're sure to be impressed when you play Bonanza slot from BTG.

The Only Thing We'd Change...

Our main gripe about Bonanza is that the free spins round can be pretty tricky to trigger. You have to be lucky to get your hands on this bonus game. Other than that, Bonanza is a great game that offers up all sorts of winning potential.
