About Bonanza slot

You may have heard the word bonanza in any context before? Often it is used to reinforce something positive. A football team can stand for a goal bonanza if you score a lot of goals and there can be a full bonanza on the stock market if all the curves point upwards. The word originally comes from the Latin word for ”calm waters” (for seafarers). The Latin "bonacia" has since over the centuries acquired a broader meaning and it was in the California Gold Rush in 1848 that it really came on the wallpaper.

One day in 1848, adventurer James Marshall found gold in the mountains between the Nevada desert and California. It was the start of a gold rush and a movement of people like no other. It is this period that Bonanza slot is all about.

The game screen is supposed to depict a mine complete with mine passages, carts, water wheels and, of course, also various precious stones and gold. The Shape of the game screen is actually clearly unique and one reason for that is that it has to fit up to seven positions on each of the six reels. In addition, the mine carts above the regular wheels play a role; they add another position to the wheels 2-5!

It can be somewhat tricky to instantly get a complete picture of how Bonanza works. The Shape of the game screen makes it a bit difficult and for many it is unusual to play with so many possible winning combinations (megaways) and symbols of different sizes. After a couple of spins, however, you've probably gotten into the game. With at least three symbols of the same kind in succession on adjacent reels from left to right, you win!

The pace of play is extremely high. The reels spin fast and the background music, which can best be characterized as a cowboy gang at full gallop (think: the signature tune of the TV series Bonanza) sets the tone. In the free spins round, you can also, if you get to take part in big wins, Enjoy classic works in a dancing cowboy style!

Bonanza slot features

Stakes and winnings

With its six reels measuring up to seven or eight positions in height, Bonanza obviously has no regular paylines. Instead, the game has a total of up to 117,649 ways to win. Big time gaming's term for this feature is MegaWays . Since the symbols are of different sizes (in height), however, it is only rarely that you get more than 15 000 – 20 000 profit routes. You can see the number of winning ways in each spin in a small box above the reels.

With win paths, there is no need to talk about coin values and bet levels. Instead, the total bet is completely in focus and all winnings are simply multiplied by the bet. You play a spin for between 2-200$.

For all slots, there is always a mathematical maximum win and a ”recipe” for reaching it. We are sure that Big Time Gaming has calculated the maximum win for Bonanza, but it has not been communicated in any way. It is possible that the zeros would not be enough! In Bonanza you can win incredible amounts.

You can win up to 50 times the stake per single win path and this win can be multiplied by basically unlimited multipliers! There will be many zeros there!

Bonanza RTP is not as impressive. Over time, the theoretical Payback is 96.00%. Sure, it's not a completely lousy figure, but it's not entirely convincing either.


Four gemstones (diamond, ruby, topaz and emerald) serve as high-win symbols in Bonanza. In addition, there are six letter/poker symbols (A-9) that can be classified as low – win symbols. The reels also feature wilds and scatter symbols. The jokers represent dynamite guys while the scatter symbols are in the form of gold bars. A bit special is that the scatter symbols are of four kinds with four different letters. It's about gold bars with the letters G-O-L-D.


Bonanza offers a veritable bonanza of special features. The MegaWays feature is perhaps the main special feature of the game, but there is much more to explore.


The Gold Diggers in California had a difficult task and the gold prospecting was fraught with dangers. One of these was constant landslides. Big Time Gaming has incorporated this detail into Bonanza by providing the game with an Avalanche feature. Each winning combination gives rise to an avalanche of exploding symbols and replenishment of new symbols from above.


The jokers in Bonanza don't immediately show up precipitously in the quarter. In addition, they can only be displayed on the additional row of icons that appear above the reels 2-5. With the astronomically many profit paths, they still make great use of linking profit paths.

GOLD-scatters and free spins

As I said, there are four scatters, each provided with a letter. If all four appear on the screen in one spin, you win 12 free spins. It is far from a picnic to manage to activate the bonus round, but if you do, you get to play the bonus round which is probably the most lucrative ever.

As you play your free spins, each Avalanche will cause the win multiplier to increase. With a couple of avalanches already in the first spin, the multiplier jumps up to 3x instantly and so it can continue. In the rules of the game it is written that the multiplier is unlimited!

With a little extra flax, you can also get even more spins to play. Three extra gold scatters in the mine carts will give you 5 extra free rounds. Four extra scatters give a full ten extra free spins.


Bonanza belongs to the top tier in terms of popular games at basically every online casino that has the title in its range. The fact that the winnings can really be absolutely majestic is a reason for the interest in the game. Another reason is the fast pace. There is really a lot going on in every spin of this title.

So, does Bonanza live up to the hype? It's something you have to decide for yourself. The advantages of the game we have mentioned in detail above. They are many and the game really stands out from the crowd. However, there is no getting away from the fact that the RTP of the game is in the lowest team.
