Bonanza Slot Features

This BTG slot has a unique layout — 6 vertical reels and a horizontal one that shows a different number of symbols on every spin. As a result, the number of paylines varies with each new round. Overall, the slot carries up to 117,649 ways to win.

The minimum bet is $0.20, while the maximum is $20, giving you a wide range of betting options. You can activate the auto spin function and choose the number of spins you want (up to 100), letting the software do all the work.

Bonanza Slot Graphics

Despite the fact it was released in 2016, Bonanza is a mine-themed slot that boasts solid graphics. The game is packed with high-value symbols in accordance with the theme — diamonds and gems. Once you form a winning combination, the symbols explode, adding visual depth to the game. The backdrop is in sync with the theme, as well, displaying a wood cabin surrounded by big rocks.

How to Play the Bonanza Slot

How to Play the Bonanza SlotDespite its unique layout, Bonanza has simple gameplay. However, before pressing Play, you’ll have to create an account in an online casino of your choice. Check out our recommendations and sign up. Alternatively, you can try the game for free here before committing and investing real money. 

Once that’s done, you should set the bet amount and start spinning the reels. Or you can activate the auto spin option, sit back, and enjoy. 

Bonanza Online Mobile

The Bonanza slot was designed with flexibility in mind. The game uses cutting-edge technology and HTML5, achieving a responsive and mobile-friendly layout. As a result, you can enjoy the slot on your computer, tablet, or smartphone. Thanks to its responsiveness, Bonanza is compatible with all operating systems — Mac, Windows, Android, and iOS.  

Bonanza Slot RTP

Bonanza has a return-to-player rate of 96%, meaning it falls under the average RTP category. At the same time, it’s a highly volatile game, meaning you could cash in on large prizes, just not as often. Bonanza is geared toward players with thicker wallets because you might go through dry spells without a cent in sight. 

Bonanza Slot Bonus Features

Bonanza has only one bonus feature — free spins. Once you land four symbols that spell out G-O-L-D, you’ll receive 12 free spins. You can activate 5 more with each scatter you collect. However, that’s not the most important element — the unlimited win multiplier is. 

This option is only active during free spins and increases with every win you score. There’s no telling how high it can go, though, so you’ll be in for plenty of fun. 

You can also trigger additional Bonanza free spins — with 3 or 4 scatters, you can win 5 or 10 extra free spins.  

How to Win on the Bonanza Slot

How to Win on the Bonanza SlotBonanza offers up to 117,649 ways to win. To claim a prize, you need to line up matching symbols in adjacent reels, starting from the leftmost one. The more symbols you connect, the higher the payout. Of course, the prize also depends on the symbol combination. For instance, green, blue, and red gems and a diamond are the highest-paying symbols in the game. Collect six diamonds, and you get 50x the wager.

Final Thoughts

Bonanza is a slot that has put the Megaways mechanic on the map. The innovative six6-reel layout with one horizontal reel creates unique gameplay, while the Megaways engine boosts the number of paylines and winning odds.

Although triggering big wins and getting free spins is rare, once you land a prize, it’ll be worth it. If you want to try the game, do it here for free. Just press Play and let the adventure begin!
