Dig for precious prizes and play with more than 100,000 ways to win in Big Time Gaming’s popular Bonanza slot! You could also win more than a dozen free spins if you trigger the Free Spins feature, while the reactions mechanic can lead to multiple wins on just one spin! Check out our Bonanza slot review below to discover everything you need to know before you play this hit game!

Bonanza Slot Details and Technical Features

Bonanza is played on six reels with thousands of ways to win, thanks to the unique Megaways system from Big Time Gaming. It takes place in a mine surrounded by detailed grass, bushes, and a quaint shack with a warm glow inside. The animated water wheel on the right-hand side of the screen adds to the game’s relaxing atmosphere, too. 

You need to match three or more symbols on adjacent reels to build a winning combination. Each time you win, you’ll trigger a reaction on the reels: all winning symbols will explode and get replaced by others, which come in from above and from the right (in mine carts). That means you can win again and again on a single spin!

A mine cart will add a symbol to the reel below it, but only on reels 2, 3, 4, and 5. The Bonanza casino slot uses the Megaways system, so each reel (alone or with a mine cart) can include as many as seven symbols. And any spin may have up to 117,649 ways to win! 

The current number of ways to win is displayed at the top of the screen, and changes from spin to spin. Press the ‘spin’ button to play Bonanza slot on any device and watch to see if you can land a winning match! 

If you want to adjust the size of your stake at any time, use the arrow buttons in the ‘stake’ section of the control panel below the reels. 

Game Symbols 

The Purple Gem is the highest-paying symbol in the Bonanza mobile slot. This is worth 2x, 5x, 10x, 25x, or 50x if you match two, three, four, five, or six on adjacent reels. 

The Red Gem pays up to 7.5x your bet. Land three or more of the Blue or Green Gems to win up to 2x. 

The Ace and King symbols offer a maximum of 1.75x your bet, while the Queen and Jack award a top prize of 1x. The 10 pays up to 0.9x, and the 9 is worth up to 0.8x. You may also see Wild and Scatter symbols from time to time — we’ll cover these in detail later in our Bonanza online slot review. 


Big Time Gaming’s Bonanza slot UK has an RTP of 96% and high volatility. You can bet between 0.20 and 20.00 per spin.

Bonanza Slot Bonus Features


Wild Symbol

The Dynamite Wild symbol substitutes for all other symbols apart from the Scatter, though they only appear in the mine carts. 

Scatter Symbol

The Scatter symbol can land on any reel and triggers the Free Spins feature when you match enough of them. 

Free Spins Feature

Four Gold Scatters award 12 free spins. But you’ll get five extra free spins for any additional Scatters on the triggering spin! 

This Bonanza slot bonus feature includes an unlimited win multiplier: it begins at one but increases by one for each reaction triggered. 

You may also land Free Spin Scatters on the mine carts for extra free spins: five spins for three Scatters, 10 for four. All payouts accumulated during the feature will be added to your overall winnings once the free spins end, and you’ll go back to the base game.
