Bonanza Slot

With Bonanza Big Time Gaming (NYX) transport you back to a wilder yet simpler time. A time when you could strike out on your own seeking adventure and wealth in the hills and valleys of the New World. Rumour has it that there are is gold in them hills and it’s just waiting for an adventurous soul to come along and lay claim to it.

With Bonanza video slot you could be that lucky adventurer. Are you ready to strike GOLD?

Theme, Sounds and Symbols

Big Time Gaming (NYX) have nestled their Bonanza video slot against the backdrop of a hillside mining operation, replete with wood cabin and water wheel. The only thing missing from the scene would be to see an old-timer panning for gold along the water’s edge or sitting on a rocking chair on the cabin porch.

The sound design of Bonanza online slot is amazing in its subtlety and simplicity. The background audio is a softly strummed banjo overlaid with the sounds of pickaxes striking a rock and a rolling bass drop that brings to mind an underground explosion. Spinning the reels activates a fast-paced guitar and banjo ditty that is pure old West!

The premier symbols are several valuable gems, namely emeralds, sapphires, rubies and at the top of the list the opal! A great design touch was to make the gems, bar the opal, uncut. This really added to that rustic, straight from the earth, feel of the slot reels.

To activate free spins, you need to land gold bars on the reels that spell out G-O-L-D, which while a little on-the-nose fits the theme. Also, the Wild is dynamite cluster with a burning fuse, ready to blow your winning chances sky high!

Game Mechanics

Big Time Gaming (NYX) have not failed to add in something special for Bonanza slot fans by building it on their Megaways engine which offers an incredible 117649 ways to win on every spin. They manage this massive multi-win payline setup by taking the standard 5 Row 6 Reel base game and adding an additional row with symbols above reels 2, 3, 4 and 5.

In true Big Time Gaming (NYX) fashion, they have made it possible for every player, irrespective of budget, to enjoy Bonanza’s amazing 117649 ways to win by offering an all-inclusive betting range. Bonanza spins start as low as €0.20 and go as high as €20.00; you choose your stake based on your preferred playstyle and budget.

Keep in mind there is always the chance to strike it rich, and Bonanza offers up to 10,000 your bet as a jackpot reward. The higher your stake, the higher your payout if it’s your lucky day!

Special Features

Bonanza is a slot machine loaded with interesting and rewarding features. Most notable being Reactions and Free Spins which ensure you get to take full advantage of all 117649 pay lines!

Dual Cascading Reactions

Bonanza video slot works on Reactions, also known as cascading reels. All symbols in a winning pay line explode causing the remaining symbols on the game screen to cascade, filling the gap with new symbols and potentially unlocking new wins.

However, when the top row of symbols are known as the Cart, in keeping with the mining theme, complete a winning pay line, these symbols also explode and need to be replaced. Rather than cascade down as in the main game, the Carts roll in from the right, revealing a new Cart symbol.

In this way, Reactions are triggered in both the main game and the Cart row, increasing your chances to win big on any of Bonanza’s 117649 ways to win.

Free Spins and Bonus Spins

In any online slot, Free Spins pure gold and this has never been truer than in Bonanza. Trigger up to 12 free spins by landing gold symbols containing the letters G, O, L and D on the reels. During the Free Spins Bonus Feature every time you have a winning pay line, or Reaction, the win multiplier for the round increases by +1. Best of all the win multiplier is unlimited!

Maximise your win multipliers growth by landing additional Scatter symbols on the reels during the free spins round. An additional three Scatters will add 5 Free Spins, while an additional four Scatters will boost your spins by +10!

Play ‘On The Go’

If you prefer to take your online slots with you, then you’re in luck! Bonanza is available on your mobile device, allowing you to strike it lucky anywhere, anytime.

Big Time Gaming (NYX) have ensured that the control layout, gameplay and bonus features are the same no matter your choice of platform. This allows you to play at home on your desktop and then easily transition to spinning on your mobile without skipping a beat.

CasinoWow Game Verdict

In review, Bonanza is a fantastic slot machine with far more playability than you might think at face value. The theme is relatable and easily draws you in, while the action of cascading reels and unlimited free spins has you on the edge of your seat waiting for that mega 10,000 coin jackpot!

While this is a high variance slot, meaning it can take a few rounds to see any sizable wins, the lowest tier spin value of €0.20 allows you enjoy the slot with very little impact on your budget. We recommend spinning today to see if you’re going to strike it rich!
