Bonanza Overview

It is pretty obvious that the theme of Bonanza slot is mining. Okay, you won’t see the actual process of mining displayed on the reels, but there are gems, stones and other instruments that are used in the process. As you probably know, stone mining requires water, so there’s also a waterfall. There are many online slots where symbols include gold, gems and other precious stones, but none of them displays the whole process in the manner and the way in which that is done here by Big Time Gaming.

In terms of layout and reels, it is pretty unique as well, there are games with a non-standard number of winning combinations, but not a lot of games where the number is as high as 117,649. The carts that appear above reels two to five are also a pretty original element.

Bonanza Music

The music in accordance with the theme, it includes sound effects and the reels are turning to the tune of The Sash My Father Wore but in a faster rhythm.

Bonanza Slot Design

The very first glance at the game will give you the impression that you are on the field just in front of a mining entrance. And that’s exactly where the action is happening. The entrance of the mine is actually the screen where the reels are spinning, positioned on a rocky background. The actual reels are small scale compared to other games, as Big Time Gaming is putting an accent on the surroundings. You can see the rocky mountain covered in grass and a few trees and flowers here and there.

The design is satisfying, and the graphics are awesome, which is expected from a slot game developed in 2016. The music just gives an emphasis on the whole atmosphere, and it heralds a great win with a sound you can’t miss.

On the bottom of the screen, just below the reels, you can see the game’s logo while on the left bottom corner you the adjustable options such as the level, denomination, as well as features like Max Bet and AutoPlay are there. Bonanza Slotoffers the play button on the right bottom corner. Eager to find out more about the gameplay and the bonus features that Bonanza slot offers? Read below.

How To Play Bonanza Slot

Big Time Gaming decided to add a little bit of extra features and way more number of paylines that we are used playing with. With six reels and astonishing 117,649 paylines, you do the math and be the judge how many spins you’d need not to get rewarded with anything. If you don’t trust us, feel free to spin the reels by yourself. You can do that with setting the denomination from £0.20 all the way up to £500.00, which means it’s perfect for the types of slot lovers that are here to chill and check out these fantastic spins and how the reels work, and also for the players which are here to earn some of the most lucrative awards that the game offers by investing a lot of money in spinning the reels.

When it comes to the RTP that Bonanza Slot offers, it’s on a satisfying level of 96.00%, which is one percent more than the average Return to Player that the online slot games are offering.

Ways To Win Bonanza Slot

Bonanza slot features six reels and two to seven symbols may appear on a single reel. The number of winning combinations can reach up to 117,649 and that’s the most original aspect of this game and the reason why so many players enjoy playing Bonanza.

The number of paylines depends on the number of symbols that appear on the reels, with more symbols the number of ways to win is also increased. There are ten symbols in this game, plus additional special symbols. 

Bonanza Wagering Limit

One of the top features in Bonanza slot are the exploding reels and this feature is in total accordance with the overall theme, as the game is about mining minerals and gems and we know how that is usually done. Each time a winning combination appears on the reels, the symbols explode and disappear, and new symbols fall into their place, thus completely altering the overall composition on the reel. This feature can generate an additional win.

Bonanza can be played with a minimum of 20p, whereas the maximum amount that you can place per wager is £500. As you can see, the betting range is quite diverse which gives plenty of room to experiment and makes the game suitable for high rollers, as well as players who have a more casual approach and prefer wagering smaller amounts of money.

Winning Combinations

The winning amount in Bonanza slot is calculated by multiplying the stake with the number featured in the payline. So, for example, if a winning combination pays 10 and you have wagered £5, your winning amount would be £50. It takes three symbols to generate a win, in most instances, but for some of the most valuable symbols, just two are sufficient.

However, it should be noted that due to the high number of potential winning combinations, the payouts for the symbols of lower value and the payouts for combinations consisted of fewer symbols are a lot lower.

If you manage to hit a combination consisted of six valuable gems you can win quite a lot of money. The maximum prize in the main game is £25,000.

Free Spins

Triggering the free spins bonus can be the door to hefty winnings. The letters G, O, L and D are the scatters in this game. Makes, sense, doesn’t it? A dynamite symbol is the wild in Bonanza. With four scatters you will trigger a dozen of free spins and you can get additional five symbols if you manage to hit an extra scatter during free spins.


Big Time Gaming is known for the original approach to slot making and Bonanza is definitely one of their most unique games, both in terms of layout, but also in terms of features and theme. When it comes to variance, Bonanza features a high variance, so if you’re keen to take greater risks when playing slots then this game would perhaps be your cup of tea.

Bonanza Symbols

When you are creating a game that revolves around the theme of mining, you can expect the symbols to be like they are – all related to the mining. As expected, there are two categories of symbols divided into higher and lower valued ones. The lower valued ones are the standard deck of cards inspired symbols which start from the number nine and go all the way to the Ace. On the other hand, the higher valued symbols represent the gems and diamonds that you will find in the mining cave. Out from the higher valued symbols, the green one is the one that will bring you the least cash, while going up through the blue and red, you will reach the purple circled one, which is the highest valued symbol of them all.

To make things more interesting there are 5 extra symbols: The dynamite which is the wild symbol and substitutes all the normal symbols we just mentioned and participates in their winning combinations, and the four scatter symbols which are the letters G, O, L and D. There are lucrative rewards if you manage to get the word GOLD on the screen.

Bonus Features


Each of the symbols that will participate in a winning combination will disappear from the reels, making room for new symbols. This is known as the Reaction feature in Bonanza Slot, and it is basically a free spin or one more chance after a winning combination for a new prize.

Bonanza Free Spins

Once you manage to land four of the G, O, L and D symbols, you are in for a free spins feature. When this happens, you won yourself 12 free spins plus 5 for each letter.

Each new symbol from these four will give you five to ten free spins.

Bonanza Jackpot Winners & Payouts

As it was already stated in the first section of this text, Bonanza is not a progressive jackpot but an online video slot. There is no doubt that many players have received the highest payouts in the slot at some online slots or casino site.

Almost every online casino displays information about their recent winners as well as the amounts they’ve won. So, if you visit the homepage of your favourite online casino, there is a good chance that you will see a list with number of players who have received the highest payouts in Bonanza. Unfortunately, if you search online for Bonanza jackpot winners, you’ll not find any lists out there because the game is not a progressive jackpot.

When online video slots are in question, there are not many slots sites that list players who had luck on their side to get the highest payouts when playing on a certain slot. This doesn’t mean that there aren’t any. You just need to google and find the ones that do, but you should know that there aren’t many.
