Play Bonanza slot with the best bonuses

If you are a fan of Online Slots , you know how important it is to choose the right casino and i more advantageous bonuses . to enjoy the gaming experience in the best possible way.

From Snai a PokerStars , from 888a StarCasino , passing through LeoVegas , Eurobet And many others, you can find Bonanza on practically all the main gaming platforms, but my advice is always to try starting off on the right foot by activating one of the various options. welcome packs , that they are No Deposit Bonuses o dei generici - or of generics Free Spins .

Keep in mind that every bonus can vary from casino to casino, and some may be subject to specific terms and conditions, so remember to carefully read the information sheet before activating any offer.

Bonanza slot symbols and payouts

It is true that the slot of Big Time Gaming lets play with gemstones just like in Starburst , but this is a theme that has been repeated several times in the casino world, while if the boulders make you think about Gonzo's Quest , I can already tell you that the game mechanics are totally different!

So let's not stop at a superficial glance and let's go straight into the mines of Bonanza!

The symbols of the slot

Among the most precious ones we find 4 gems of different colors: the purer the gem, the higher its payout!

In addition, we have the 6 traditional playing card symbols, from 9 to Ace.

The three lit dynamite sticks are instead the Wild symbol: they can generate a winning combination by substituting all other symbols except for the Scatters, represented by the letters that make up the word GOLD.

Symbol payout table


Each of the 6 reels of the Bonanza slot allows for obtaining 2 to 7 symbols (the 4 central reels are joined by the carts of a seventh reel that works horizontally), and we have already mentioned the Megaways of... Big Time Gaming , which here reach up to a staggering 117,649!

These are the winning lines that result from the composition of the grid on each individual spin on the slot: you can monitor them as they update at the top during the spins, to always know how close luck is!

In addition, every win on the reels triggers "reactions", in which the stones explode to make room for new symbols: winning combinations are formed with 3 or more identical symbols placed on adjacent reels, starting from the first reel on the left to the right.

Minimum bet and maximum bet, the Autoplay feature

Playing the Bonanza slot is possible from a minimum bet of $0.20 to a maximum bet of $30 in online casinos .

Autoplay mode is obviously available, thanks to which you can set not only the number of automatic spins, but also the loss limit and the limit of a single win to stop the series.

RTP (Return To Player)

The RTP of 96% ensures an excellent return to the player and makes us even more tempted to linger in search of treasures in the mine!


This game belongs to the category of slots with high volatility , which means that the winnings won't necessarily be constant, but when they do come they could be of great value.

In particular, the Reactions feature could lead to a streak of winnings and even higher cashouts!

Jackpot and maximum win

Although it's not a jackpot slots , on these reels it is still possible to obtain a maximum win equal to 333 times the bet per spin!

A literally explosive slot!

Bonanza is a real fireworks display for gameplay and game mechanics, capable of keeping even the most experienced player on the edge of their seat. Thanks to the Wild dynamite and a favorable RTP, the chances of winning big prizes are truly countless, just like the Megaways. And the adventure promises to be even more exciting!

The functions of the slot

We said that every single win triggers reactions, but that's not the only special feature offered by Megaways slots .

But let's start in order and see how this mechanic works in detail!

The reactions

Take a look at the reels! At the top of these, you see a track with carts that carry out 4 symbols from the mine with each spin, from right to left, aligning with the four central reels.

As already mentioned above, thanks also to the addition of this horizontal reel, all vertical reels can contain up to 7 symbols each.

But what happens when we get a winning combination? As you will soon notice after every reaction win, the disappearing symbols are replaced in two different ways:

  • by symbols that fall from above for the reels (the usual 'cascades' of symbols);
  • from the right for carts with new symbols popping out of the mine.

The free spins

What do we do in front of a mine, except to enter it and find gold?

Scatter symbols are the letters that spell the word GOLD and award 12 free spins !

These free spins are invaluable: each spin is boosted by the progressive win multiplier that applies to all winning combinations in the series!

The box reporting it to the right of the grid starts at the value of 1x, and never ends!

In short, it is an unlimited multiplier, which increases by one unit with each reaction win and has no maximum achievement threshold!

But the surprises don't end there, because finding another Scatter on the reels will give you an additional 5 free spins.

More Scatters will then pop up during the free spins, but this time only in the trolleys at the top of the grid. In detail:

  • with 3 Scatters in the carts you will get 5 more free spins,
  • with 4 Scatters you will receive 10 more!

There is gold in the Bonanza slot mine, let's pack the bag!

Every spin could be the right opportunity to trigger a chain reaction, and if we are lucky enough to find the GOLD Scatters, then we can enjoy even more our search for treasures in the exciting free spin mode, where the multiplier has no limit and could catapult us towards truly epic wins!

The colors yellow, red, purple, blue, and green distinguish the most precious gems, but also pay attention to the Scatter gold bars, which stand out from the other symbols with the thud they make when landing on the reels!

What to do if you have problems while playing

If you find yourself stuck during a game on the Bonanza slot machine, don't worry and don't give up right away: often the error is due to a slowdown in the connection or a temporary glitch on the platform.
