Bonanza Slot Big Time Gaming

Bonanza is video slot which features 5 reels and 117649 paylines. It is powered by Big Time Gaming software provider and is inspired with the mining industry.  The reels look pretty great and designed superbly as is the entire game.

How to Play Bonanza Slot

Before you go mining for treasure, you should set your bets, and here’s how you can do it:

  • Stake will help you adjust coins size which is essentially makes your total bet.
  • Play will set the reels spinning once you decide on the amount you wish to bet
  • Autoplay is used to set the reels into the automatic motion series for the preset number of times which you choose. 

Slot Features

Now, let’s see what Bonanza slot has to offer to all of us should we decide to take these reels for a spin. This is not a slot which would actually fall under the category of action packed slots, but it still can offer entertainment which will keep you occupied for hours.

The Wild symbol in this game is represented as the dynamite, and it can substitute for any other symbol except for the Scatters. 

Each Mine Cart adds a symbol to the reel and it is set above for reels 2, 3, 4 and 5. Every winning symbol that is a part of reaction and is replaced by symbols coming from above on the reels and from the right in the carts.

Free Spins

The game has 4 Scatters: letters G, O, L and D. If you land all 4 of these on the reels you will win 12 free spins. Additionally, every scatter during free spins adds an extra five spins.

During Free Spins you can win an unlimited multiplier which increases after every reaction you create. Free Spin scatters appear only in carts, 3 scatters add 5 extra free spins, 4 scatters add additional 10 extra spins.

The game concept is brilliant, cascading wins are nice and the free spins are nice to get too when they come in but please read the bad points as they explain better.


TERRIBLE RTP, simple as that, you can put thousands through this machine with stupidly small returns. BTG are a disgraceful company hiding behind the "Highly volatile" comment which seems to entitle them to take your money knowing that one day someone might get a big win to level the RTP. All of their machines are the same and if your reading this find another game manufacturer to use and do not use any BTG. Oh and why should you listen to me? I have over £100k through these machines and can provide very good feedback. BTG if you're reading this shame on you.

Bonanza is no question the most popular slot Big Time Gaming ever released. The game has 6 reels and up to 117649 paylines which is something you won't see often at all. The bet ranges from 0.20$ up to 10$ per spin, making it great for all types of players, with potential being massive as you can win 10,000x your bet.

The symbols in the game are quite which is something I like a lot. The premium symbols are Diamonds, Rubies, Sapphires, and Emeralds. There is also a generic card deck consisted of 9, 10, J, Q, K, and A being low paying symbols. The slot pays left to right, beginning from the leftmost reel, and three of a kind is the minimum for landing payouts. Apart from a regular reel, there is also the horizontal reel that you can see on the top of the screen, up to 4 random symbols can appear and help you connect your winnings.If it happens then all winning symbols will explode and make room for new symbols to appear making you win multiple times in one spin.

There is only one feature in Bonanza and that is free spins. In order to trigger them, you need at least 4 scatters symbols(GOLD) if you manage to get all of them in one spin you will be awarded 12 free spins, to begin with. It's important to mention that with every additional Golden Bar that appears you can win extra 5 free spins up to 3 times. Once the free spins start the Unlimited Win Multipliers are activated. You will start with 1x multiplier but with every winning combination, it will increase by 1x, for example, if you have 10 winning spins your multiplier will be 11x. There is also a wild symbol in Bonanza but it is a little bit different than in other games. You will be only able to get up to 4 wilds, which is more than enough to get some nice winnings.

Everyone at this point probably heard or played the Bonanza and that's for the reason. This game can keep you playing for hours not only with potential it has but the music of the game is also really nice, combined with amazing graphics it's just a top-notch. I have never got some massive winnings such as 1000x, but there were plenty of 100-300x winnings. That's why I am gonna keep playing Bonanza until I eventually make it bless me with some mega wins.


Seeing paytable can remind you how rough Bonanza can be, as the best paying symbol(Diamond) can get you only 50x for 6 of them, and the second-highest paying symbol only 7.5x your bet which is disappointing. At the end, it's all about getting a lot of megaways and multipliers during free spins, which by the way can be really hard to get. Sometimes it can take up to 1000 spins in the base game to trigger the feature.

Bonanza Megaways is probably one of the most popular online slot nowadays and I think its' peak was last year when many players were showing their big wins, many of them exceeding 1000x bet. I had played Bonanza several times before but not for long sessions therefore I never really had the experience of achieving mega wins. But I really enjoy the megaways concept and this was one of Big Time Gamings' hits when it comes to megaways slots.

A few days ago I decided to make a deposit and dedicate the session to Bonanza to give it a fair try. The minimum bets are 0.20 eur per spin so I decided to stick with the minimum for the entire session. I have seen other askgamblers members posting wins of 1000x bet on minimum bets and that would be a lovely win even on a small bet.

The game itself is quite simple in it's concept- on each spin there are different megaways activated and every consecutive win will make a cascade and drop new symbols into their places. But I'm sure that the main goal is to get GOLD symbols anywhere on the reels to trigger the bonus round. The standard bonus round is 12 free spins with increasing multiplier for every win. In my session I managed to get a +5 scatter symbol few times so I was playing with 17 spins instead. What I noticed is that it's very important to get many small consecutive wins in the beginning of the free spins to build up the multiplier. I was lucky enough to not only retrigger the bonus for extra 5 spins but also boosted the multiplier to 18x which resulted with me getting my biggest win on Bonanza of 245x bet.

After having a couple of hour long session with the game I noticed that the game has weirdly calming effect on me, I find it simple yet with great potential and even the base game with a few diamond wins can give a solid boost- my best was 50x base game win.

Another good thing is that it's a good game for wagering, in my opinion, as my balance was quite steady for the most of my session or at least wasn't going down quickly. I do think that the free spins can be difficult to trigger but it's certain that they hold great potential. After this session I'm sure I will play this game more.
