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 hugely generous format and its exciting bonus features.

Although the single top win from a payline is not massive (x50) the fact you can hit win upon win upon win with so many winning ways makes the wins available from a single spin of the reels pretty substantial. We love this game and think you will too...

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 maker has taken a lot of time to create this beautiful scene, and you won't be disappointed.

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. There are six reels, and while they're spinning hillbilly music plays continuously. It's fun, and you'll be dancing in your seat.

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.

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.

When using the Autoplay function, you have the option to set a loss limit and a single win limit. The single win limit comes in handy if you're the kind of player who likes to quit while they're ahead. If you've hit a large win, the game will stop playing, and you'll be able to determine whether or not you want to collect those wins or keep spinning.

The loss limit setting is one that we would advise using, no matter what your budget. 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.

The top prize available in Bonanza is worth 50x your stake, and it's awarded by the diamond symbol. It is, by far, the most generous symbol in the game, as the next most generous prize is worth 7.5x your stake.

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 an impressive 12000x your wager.

Free Spins Feature on Bonanza

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. It can be pretty difficult to trigger, but if you do, you'll be laughing all the way to the bank.

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 very generous 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.

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.

Bonanza Slot Free Play

Before you get playing Bonanza online slots, it's always advised that you give the 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.

Bonanza Slot - The 150 Spin Experience

If you just don't have time to play 150 rounds of Bonanza slots right now, then we have you covered. our 150 Spin Experience provides you with the in-depth insight you need before giving this game a spin.

  • Our bet. We decided on a stake worth 5, which should be a fair compromise between players who have limited budgets and those with a bit more cash to spend on slots. It's easy to adjust your wager using the tool in the bottom left-hand corner of the screen. Just click the arrows until you've arrived at the stake you prefer.
  • Graphics and gameplay. Just as you would expect a Big Time Gaming slot to play, Bonanza has smooth gameplay and impressive graphics. Even with a few windows and tabs open, the game runs very smoothly and the graphics are just as eye-catching as they are in screenshots.
  • Our wins. As a high volatility game, Bonanza is the kind of game that pays out very generous prizes - albeit less frequently than in medium and low volatility games. As a result, we were left waiting quite a while between significant wins. The most common prizes that we earned range from 3x to 4x our stake, but we did manage to cash in on a couple of prizes worth 20x our stake.
  • Bonuses. The cascading wins were awarded frequently, so we benefited from the multiple payouts often. Unfortunately, we weren't able to trigger the free spins round. This is where the Feature Drop would have come in handy. Still, it's a randomized game, so you may have better luck than us!

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.

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.

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.

Mega Megaways 30/11/2019

This is one of the best megaways games in my opinion. Loads of free spins that are quite easy to trigger and managed a 25x unlimited win multiplier. There are loads of megaways games now but this one is a lot of fun and definitely worth a spin.
