This is one of the highlights in the Bonanza slot and the reason it’s such as hit. The game uses Megaways, which means there are 117,649 ways to win. Essentially, this means that combinations activate in just about any direction as long as matching symbols appear consecutively from left to right.

Min/Max Bet and Autoplay Options

Most would think such a large number of ways to win would require a massive wager, even at minimum bet. However, it’s clear that the developer kept that in mind and managed to start betting from just $0.20, ranging up to $20.00 per spin. The options are adjustable above the spin button on the right, including the autoplay function where you can set limits and choose the number of rounds.

Bonanza Slot RTP

The Bonanza slot presents an RTP (Return to Player) percentage of 96%. Impressively, this is above the industry standard and what you’d expect from a well-known game developer.


The highly valuable Megaways function makes big winnings possible but activating them might take some time with the volatility ranging from medium to high. Something to consider when choosing your bet per spin.

Jackpot and Maximum Win

No progressive jackpot is linked to the game, but that doesn’t mean big winnings aren’t possible. In fact, winnings of up to 26,000x your bet can trigger when you least expect it. Even at the lowest wager, this adds up to massive rewards!

Game Features

Modern slots provide some of the best entertainment with special features that also deliver incredible winnings. The Bonanza online slot has loads to enjoy, and also comes with the bonus buy option. So, let’s dive in and discover what we’ll find deep down in the mine!

Wilds, Carts, Free Spins, and Reactions Stack up Big Wins!

It sounds like a lot, right? Well, the great news is, the slot does everything by itself, allowing you to sit back, relax, and enjoy the winnings as the features trigger. Here’s what each of them adds to the game:


With each standard game spin, four carts loaded with random symbols come to a stop above the reels. This extends the second, third, fourth, and fifth reel to include an additional symbol. Of course, this helps claim even more combinations as these symbols can link up with those on the reels.


Completing a combination comes with more than just a payout. The symbols involved explore and allow more rocks to drop down in their place. If these new symbols line up with others, another combination and reaction will activate. This continues until no additional combinations trigger.

Wild Dynamite

That’s right, these wilds are lit and ready to blast some rock to reveal more gems! Represented by the red dynamite sticks that only appear in the carts on top, the wilds can represent any standard game symbols. This means even more combinations for anything other than the scatters.

Golden Scatters Lead to Free Spins!

This mining theme might focus on high value gems, but you’re bound to find some gold along the way, and when you do, you free spin trip to the bank has started! The golden symbols are the scatters that can appear anywhere, but you’ll need four of them in a spin to activate the free spins bonus. Getting more than four is a huge advantage as each of them adds another five free spins to the initial 12 spins.

Bonanza Slot Scatter Symbols

Unlike the standard game, the Bonanza free spins feature adds the benefit of multipliers that increase with every reaction. It starts at the standard 1x and increases each time a combination activates, offering bigger winnings for each free spin that follows. get another three or more scatters and add up to 10 additional spins.

Bonus Buy

The free spins sound incredible, right? However, holding on for four scatters to eventually make their way to the reels could be a buzz kill. Luckily, you have the option to purchase the free spin feature at any time by pressing the purple button on the left.

Bonanza Graphics & Sound

The Bonanza slot was released late in 2016, but still delivers better graphics than you’d see from some other developers. The animations don’t seem old and still provide a great experience, especially with reactions. The game sound is a fast-paced wild-west jingle, which is bound to keep you on the edge of your seat. If it’s not your type of thing, simply press settings to turn in down or off.
