Bonanza Slot Theme 

The Gold rush, the Bonanza of gems takes you to the mountain, where you will dig deep to find the Bonanza symbols that give you big winnings. On top of the six rock reels you will find helpful mining carts, bringing you the Bonanza symbols that will aid you in the mining process. Great banjo wild west music amps up the excitement as you play. 

On the left side of the slot below the rocky, yet full of grass and pants mountain side, you find a miner’s cabin. To the right side of the slots a water wheel is rotating harvesting the natural power of the mountain waterfall.  The graphics are computer generated and peaceful and nice to look at as you spin the rocky reels that contain loads of gems and other symbols. 

Dynamite will aid you when they pop up on the reels that shift in size, you could get a few reels with 3-4 symbols and some with up to 7 symbols, the more symbols the more ways you can win.

How to Play the Bonanza Slot 

To the right of the reels you will find your stake, you can click on the green arrow buttons to change the bet from 20 cents all the way to 20 dollars at the most. 20 cents at the time until 1 dollar, then 2, 4, 5, 10 and finally 20 dollars.  

Below the green arrows you find a blue menu button to the left. This will explain the Bonanza Rules, Bonanza Payout and Bonanza Symbols to you in great detail. Next to the menu button you find the dark green auto spin button, this will allow you to choose the number of spins you want, the loss limit and single win limit. Once you have selected this you can sit back and watch the reels spin over and over, without having to press the spin button. That big green spin button is located under these two buttons if you like to start each spin yourself, or maybe use a Bonanza stake strategy to increase your winnings.  

On top of the reels four mining carts will roll down the line and function as additional symbols. These start on reel 2 and finish at reel five. Any carts used in a winning combination will explode and the remaining carts will move down the line and additional carts added at the end. 

As the rocky reels spin, you can win any way from left to right. Two or more diamonds pays, all other symbols pay with three or more. Any symbols that pay will explode, this makes the above Bonanza symbols fall down and new symbols fall down to on top to replace the winning symbols. The additional symbols will have the same size as those already on the reel. This means that if one symbol explodes on a reel with three symbols, it can only be replaces with one, not two or more symbols to give reel more symbols and the spin more ways.  

You can play Bonanza slot with real money or for fun. Depending on if the casino offers free play.  


Our Bonanza slot review found an appropriate wild symbol for a mining slot, three sticks of dynamite, lit and ready to blow. The dynamite wild explodes in any winning combination and disappears as any other symbol.  

Bonanza Free Spin Feature 

GOLD is the keyword that unlocks the free spin feature on the Bonanza online slot. These scatter symbols can appear on top of each other (more than one, on a reel) on all six reels. Winning with other symbols can drop GOLD symbols in their place. Any additional Gold symbols to G, O, L and D will add 5 spins to the free spin feature.  Once you start the free spin feature the background of the Bonanza slot turns red. Each win will up the win multiplier. The Win multiplier is unlimited. 

During the free spins there are no GOLD symbols on the reels. You can still win more free spins as carts stacked with gold bars can appear amongst the carts. you need the gold carts to add 12 new spins to your feature.  The free spin feature can give you a big Bonanza Payout if you are lucky in your mining efforts.  

Bonanza Payouts 

The highest winning symbol on the Bonanza online slot is a sparkling diamond. two diamonds give 2 credits, three give 5 credits, four give 10 credits, five give 25 credits and six diamonds give 50 credits. 

The second highest winning symbol is a shiny uncut red emerald.  Three red emeralds give 1 credit, four give 2 credits, five give 2,5 credits and six red emeralds give a 7,5 credits prize. 

The next symbol on the payable table is an uncut blue sapphire.  Three blue sapphires give 0,25 credit, four give 1 credit, five give 1,5 credits and six blue samphire give a 2 credits prize. 

Then we find an uncut green emerald on the payable table Three green emeralds give 0,25 credit, four give 0,5 credit, five give 0,75 credit and six green emeralds give a 2 credits prize. 

The lower paying Bonanza symbols are as usual based on card symbols. The one paying the most being A. 

Both A and K pays the same. Three payable give 0.2 credit, 4 give 0,4 credit, five give 0,6 credit and six of either A or K give a 1.75 credits prize.  

Three Q`s give 0.2 credit, 4 give 0,25 credit, five give 0,6 credit and six K`s give 1 credit. 

Three J`s give 0.15 credit, 4 give 0,25 credit, five give 0,5 credit and six J`s give 1 credit. 

Three 10s give 0.15 credit, 4 give 0,25 credit, five give 0,5 credit and six 10s give 0.9 credit. 

The lowest paying Bonanza symbol is a 9. Three 9s give 0.1 credit, 4 give 0,2 credit, five give 0,4 credit and six 10s give 0.8 credit. 

There are quite a few symbols, but with Megaways, you can get many reels with 6-7 symbols. This increases your Bonanza Odds and can give you big winnings.
