Slot Mechanics & Gameplay

Megaways mechanic

The Megaways mechanic is the star of the show in Bonanza. With up to 117,649 ways to win, the game offers an unparalleled level of excitement and potential. The number of symbols on each reel changes with every spin, keeping players on their toes and providing endless possibilities.

Cascading Reels

Bonanza’s cascading reels feature is another highlight. Whenever a winning combination lands, the successful symbols explode and are replaced by new ones falling from above. This process continues until no new wins are formed, allowing for multiple payouts in a single spin.

Betting Options

The game offers a wide range of bet sizes, catering to both casual players and high rollers. While the Megaways mechanic means that paylines are not adjustable, players can still customize their betting experience to suit their preferences.

Autoplay Function

For those who prefer a more hands-off approach, Bonanza offers an autoplay function. Players can set a number of automatic spins and customize loss and win limits, ensuring a tailored gaming experience.

Paytable & Symbols

Bonanza slot symbols and Paytable

Regular Symbols

Bonanza’s paytable features a mix of precious gemstones and classic playing card suits. The gemstones, including diamonds, rubies, and emeralds, offer higher payouts, while the card suits represent the lower-value symbols.

Wild Symbol

The wild symbol in Bonanza is represented by sticks of dynamite. These wilds substitute for all regular symbols, helping players form winning combinations more easily. However, they only appear on the extra horizontal reel above the main reels.

Scatter Symbol

The scatter symbol in Bonanza is spelled out as “G, O, L, D.” Landing four or more of these symbols anywhere on the reels triggers the game’s free spins feature, which we’ll explore in more detail later.

Bonanza Special Features

Free Spins

Bonanza’s Free Spins feature is where the real excitement begins. Triggered by landing 4 or more scatter symbols anywhere on the reels, this bonus round awards 12 free spins with the potential for even more. The unlimited increasing multiplier is the star of the show, growing with each cascading win and leading to some truly mind-blowing payouts. If you’re lucky enough to retrigger the feature, you’ll add extra free spins to your count, keeping the adventure going even longer.

Extra Horizontal Reel

One of Bonanza’s unique features is the extra horizontal reel that sits above reels 2-5. This special reel adds an extra symbol to each of the reels below it, increasing your ways to win and boosting your chances of hitting those coveted combinations. Keep an eye out for the wild symbol, which can only appear on this extra reel and will substitute for any other symbol except the scatter.

Bonus Buy (not available in all jurisdictions)

For players who can’t wait to dive into the Free Spins feature, Bonanza offers a handy Bonus Buy option. By purchasing entry to the bonus round, you’ll skip the base game and jump straight into the action. However, keep in mind that this comes at a cost, and the RTP implications may vary. It’s also important to note that the Bonus Buy feature is not available in all jurisdictions, so check your local regulations before getting too excited.

RTP, Volatility & Max Win Potential

RTP (Return to Player)

Bonanza boasts a solid 96% RTP, which is right in line with the industry average. This means that for every $100 wagered on the game, players can expect to see around $96 returned to them over the long run. While this doesn’t guarantee a profit, it does provide a fair and transparent gaming experience.


As a high volatility slot, Bonanza is not for the faint of heart. This level of variance means that wins may be less frequent, but when they do hit, they can be substantial. Players should be prepared for potential dry spells between big payouts, but the excitement of chasing those massive wins is what keeps many coming back for more.

Max Win Potential

One of the most appealing aspects of Bonanza is its incredible max win potential. With the ability to hit up to 26,000x your bet, this game offers the chance to score some truly life-changing payouts. The key to unlocking this potential lies in the Free Spins feature, where the unlimited multiplier can send your winnings soaring with each cascading win.

Tips and Strategies

Bankroll Management

One of the most crucial aspects of playing high volatility slots like Bonanza is proper bankroll management. Before you start spinning, set a budget and stick to it. Determine how much you’re comfortable losing in a single session and never chase your losses. It’s also essential to consider the game’s volatility when planning your session length, as the potential for long dry spells may require a larger bankroll to weather the ups and downs.

Bet Sizing

When you’re first starting out with Bonanza, it’s a good idea to keep your bet sizes small. This allows you to familiarize yourself with the game’s mechanics and features without risking too much of your bankroll. As you become more comfortable with the slot and start to see some wins, you can gradually increase your bet size, keeping in mind the increased risk that comes with higher stakes.

Free Spins Strategy

Triggering the Free Spins feature is the key to unlocking Bonanza’s massive win potential. While there’s no guaranteed way to activate this bonus round, there are a few things you can do to improve your chances. First, always aim to land as many scatter symbols as possible, as this will award you with more free spins. During the feature, keep an eye out for retrigger opportunities, as adding extra spins can lead to even bigger payouts. Finally, remember that the unlimited multiplier is your friend – the more cascading wins you can chain together, the higher your rewards will climb.
