How to Win on Bonanza Slot Machine

The most thrilling aspect of the Bonanza slot is the Megaways game mechanic. It introduces a dynamic and ever-changing number of ways to win on each spin, with a maximum of 117,649 ways if the reels are full of symbols. Unlike traditional paylines, this unique feature increases the chance of winning combinations and can lead to substantial payouts.

The Bonanza slot offers a jackpot win of up to 10,000 times the stake. However, the potential for massive payouts doesn’t end there. The unlimited multiplier in the free spins feature allows wins to escalate to extraordinary levels. In addition, the Reactions (cascading reels) mechanic removes winning symbols and replaces them with new ones, enabling consecutive wins on a single spin. In the base game, the purple gemstone symbols provide decent returns of 50 times the stake. However, when combined with multipliers in the free spins feature, the winning potential reaches new heights.

RTP & Volatility in Bonanza Slot

The “RTP” (Return to Player) of a slot indicates the percentage of money that the game returns to players over thousands of hypothetical spins. While an average RTP ranges between 90% and 95%, the Bonanza slot exceeds that average with an RTP of 96%. However, it’s important to note that RTP is not a guarantee of winnings, but rather an indication of the overall generosity of a slot.

Volatility, or variance, refers to the frequency and amounts of payouts in a slot game. Bonanza is classified as a medium volatility slot, falling in the middle of the spectrum. Payouts can be unpredictable, with a mix of small and large wins. This unpredictability adds excitement to the gameplay, but can also result in longer waits between significant payouts.

When comparing Bonanza with other slot games, it may not have the highest max jackpot amount. However, its potential for massive wins increases significantly during the free spins feature, where the unlimited multiplier can lead to extraordinary payouts.

Bonuses on Bonanza Slot Machine

The Bonanza slot offers two main features:

Cascading Reels

The Cascading Reels feature, although less elaborate, is notable for its frequency. This mechanic removes winning combinations from the reels, allowing new symbols to fall into place. If another winning combination forms, the process repeats, resulting in consecutive wins. This feature, combined with the Dual Reaction feature, where extra symbols roll in from the carts after a win, leads to the potential for significant wins.

Free Spins Feature

The free spins feature in Bonanza is truly exceptional. When players spell out the word GOLD with the gold letter symbols, they trigger 12 free spins. Scatter symbols appearing in the top cart can retrigger additional spins, with no limit on the number of retriggers. Each winning combination in the free spins round increases the multiplier for subsequent wins. Given the cascading reels mechanic and increasing multipliers, this feature offers an incredible opportunity for huge payouts.

Bonanza Slot Tips

  1. Have Patience – But Don’t Chase Losses: As a medium volatility slot, Bonanza may not produce frequent wins. The free spins feature can also take some time to trigger. Patience is essential, and it’s crucial not to chase losses.
  2. Set a Betting Limit: Due to the potential scarcity of payouts and feature triggers, setting a lower bet amount ensures a longer gaming session.
  3. Know When to Collect: While it can be tempting to try and double up on big wins, it’s wise to collect the majority of winnings after a profitable run in the free spins feature. Leave a small portion for possible retriggers, but avoid betting more than that.
  4. Don’t Fall for Gambler’s Fallacy: Remember that every spin is random and unaffected by previous spins. The belief that a slot will pay out soon based on its past behavior is known as the Gambler’s Fallacy and can lead to unrealistic expectations.

Bonanza Slot Free Play

Bonanza offers an exciting and complex gaming experience. Before venturing into real money play, it’s highly recommended to practice with free slot games.

Free slots can be found at top online casino sites or review sites dedicated to providing free play options.
