Bonanza is an online slot that offers great possibilities in terms of winnings, due to the 117,649 ways to win. But this does not mean that it has a progressive jackpot prize. All prizes are preset and are paid as multiples of your bet.

The minimum bet you can place on each spin is 0.20€ and the maximum bet is 50€. As mentioned before, Bonanza consists of six reels. In general, 2 to 7 symbols can appear on each reel, thanks to the MEGAWAYS game engine.

As you start searching for treasures, you can find diamonds, rubies, sapphires, and emeralds, as well as gold bars, as they will help you to activate the free spins feature that comes with expanding multipliers. The winning symbols will explode and will be replaced by new ones for many additional winning combinations. The playing cards (9, 10, J, Q, K, and A) are used for low-value symbols. The Golden Bars represent Scatters and will activate the free spins feature once you land at least three of them on the reels.

Bonanza comes with 3 additional bonus features. The centerpiece of the action is the Reactions feature, where winning symbols are removed and new ones take their place to create new winning combinations. Then there is the Free Spins feature where you start with 12 free spins. Each win triggers the Unlimited Win Multiplier feature, where the multiplier increases infinitely.


Reactions Feature – After each winning spin, the symbols that gave you the win will be removed from the reels and replaced by new ones. You then place a new bet with the new symbols on the reels. In this feature, the explosions will continue until there is no winning combination left.


Unlimited Win Multiplier Feature – Bonanza features an unlimited win multiplier feature. It applies a multiplier to any bet after each successive explosion. The multiplier starts at 1x and increases by 1 on each subsequent blast win.


Free Spins – The letters G, O, L, and D are Scatters. Get these 4 letters and you will activate the Free Spins feature where you will be awarded 12 free spins. Any additional Scatters in the spin will add another 5 free spins to your total.

You must watch out for the gold bars that appear on the reels during a spin, if you get 3 bars, you will get 5 additional free spins. While, if you get 4 bars, you will get 10 free spins. As for the Multiplier, there are no limits to this feature, which means that you could potentially have unlimited free spins.

As in all slots on the market, the frequency of winnings varies directly proportional to the volatility of the video game. In slots with low volatility, players tend to win more often, but winnings are lower. While in the ones with high volatility, it is exactly the opposite.

Big Time Gaming’s Bonanza slot is considered a high volatility casino video game, with an RTP of 96%. This winning percentage refers to the amount of money the player can expect on average in terms of prizes.

Due to the aforementioned, although Bonanza has a wide range of bets for more cautious players, the game is much more suitable for players with larger budgets. So, if you are on a limited budget, remember to be smart about the amounts you wager.

First Impression

Star RatingStar RatingStar RatingStar RatingStar Rating

Our first impression of the Bonanza slot is very good. The game takes place in a natural environment surrounded by vegetation. As we mentioned, the game is structured based on 6 reels made of rocks. You can find symbols on each of them. The symbols, depending on each spin, can vary in number between 2 and 5.

Bonanza does not have a defined number of rows which makes it possible to have 117,649 ways to win. One of the main characteristics of Bonanza is its simplicity, which is reflected not only in its operation but also in its symbols. Among the lower value symbols are the traditional 9, 10, J, Q, K, and A. The higher value symbols are represented by 4 precious stones.

Big Time Gaming’s Bonanza slot is full of adventure from start to finish. The concept is unique and entertaining and the music gives the game a fresh feel. The graphics look realistic and take you to a highly engaging place with animations.

The game was created by the innovative market leader Big Time Gaming. It also offers more than 117,000 ways to win. On top of that, the slot is packed with rewarding special features worthy of a place on any slot website. Bonanza has free spin rounds that further increase the excitement and seem to offer endless wins. That is why we encourage you to try out the experience Big Time Gaming offers you through this pioneering game and learn why it is so popular all over the world.

When you start playing, the game will take you to a beautiful retreat in the woods with green lawns, rocky surroundings and dozens of flowers. There is a cabin on the side of the screen and a constantly running water mill. Its creators took the time to recreate this beautiful scenery.

If you have a penchant for mining, Bonanza is the ideal slot for you, as you will be able to enter a world where precious stones can bring you great winnings whilst having fun.

Although you may think that Bonanza is a somewhat complicated slot to play due to the 6 reels it has, instead of 5 as is usual in most slots, we can assure you that it is quite the opposite, the gameplay of Bonanza is quite simple. Each reel shows between 2 and 5 symbols and there are additional small reels at the top of the screen. As each reel shows a different number of symbols, the total number of ways to win varies with each spin.

You can bet between 0.20€ and 50€ per spin, which is the perfect range for players with small to medium budgets. Riskier players will also enjoy the game, as they will get the most out of their bankroll.

There is an Auto Play feature available for up to 100 spins and you can set a win or loss limit. This is ideal for you if you are one of those players who like to withdraw when they are on a winning streak, to avoid losing what you have accumulated.

We recommend you use the Stop Loss feature, no matter what your budget is, as it is a very good idea to have a limit so that you don’t use up your available funds in a short period of time.

First of all, we can say that the Bonanza slot has a spectacular visual design. As mentioned, the game is set in a mine, which is located under hills with cabins and waterfalls in the background. Although the graphics are not as sharp as in newer slots, the design is very good and pleasant.

Something that stands out in this slot machine is the soundtrack used. The background sound is a very nice hillbilly style that tends to be upbeat and very exciting. Bonanza feels like you are playing a slot in a live casino, which I think is an important factor in its success and appeal.


Does Bonanza have a free spins feature?

Yes, in Bonanza you get a minimum of 12 Free Spins when the word GOLD comes up during the base game. The spins come with an unlimited win multiplier feature where each win increases the multiplier by 1, with no limits.

How volatile is the Bonanza slot?

Bonanza is a high volatility slot with an RTP of 96%.

How does the MEGAWAYS engine work?

In each spin, between 2 and 7 symbols can appear on each of the 6 reels. The more symbols per reel, the more ways to win. If you get 7 symbols on the 6 reels, you will have the maximum win of 117,649x MEGAWAYS.

Can I play Bonanza Slot for free?

Yes, you can play Bonanza for free at different online casinos. Try all the game features before playing for real money!
