Bonanza Slot Review

One major factor that makes Bonanza a rare slot is the unique 6×5 grid which the game uses. In addition, there are some profitable bonus features that can maximise payout and winning combinations that make earning a prize easy for lucky players. Taking on the familiar traits of most Big Time Gaming titles, this game features excellent optimisation and visually stunning graphics. But before we go more in depth, let’s take an overview of the game first.


One of the top features of the Bonanza slot game is the high number of paylines available. The game features over 100,000 paylines, which is an impressive count compared to most slots online. Also, the slot allows minimum bets of £0.20 and maximum bets up to £20. Though the maximum bet is unsuitable for high rollers, the payout can be huge, as the slot features many payout features and a maximum bonus multiplier of up to 10,000x.


The Bonanza slot game is a product of Big Time Gaming, so it is popular in the UK. As a result, it is available in most online casinos you will find in the region. This accessibility gives you enough freedom to play at your favourite UK casinos and offshore platforms that accept players from the UK.


Compatibility is one of the most essential parts of online casino games. Fortunately, Big Time Gaming is a company known for top-notch optimisation. Thus, the optimisation is excellent on Bonanza, and the game is accessible on all platforms. Bonanza Slot has a mobile edition which works on all mobile devices, and it comes packed with the regular features of the game, including the 100,000+ paylines.

After conducting some tests on different smartphones, we discovered that the speed was the same regardless of the choice of device. Thus, they did a good job of porting the same desktop experience to the mobile edition. Whether you use an Android or iOS device, you can log in to the mobile edition from any browser, as the game operates on an HTML5-based framework.

Pros & Cons of Bonanza Slot

Though the Bonanza slot game is a top-level slot with exciting features and benefits, there are also some downsides attached to playing the game. Moreover, personal preferences differ. Thus, we’ve included this section in the review to further enlighten you on the advantages and disadvantages to expect from playing the game.

  • Thumbs-Up Icon High Multipliers
  • Thumbs-Up Icon Easy Gameplay
  • Thumbs-Up Icon High Paylines
  • Thumbs-Up Icon Good Bonus Features
  • Thumbs-Down Icon Difficult to Win

Let’s explore the pros of playing the Bonanza slot game.

Bonanza features a maximum bonus conversion multiplier of up to 10,000x your stake. This means you can earn as high as £200,000 depending on your combination and stake value.

And as a plus, it is straightforward to play the Bonanza slot, as the game features a simple concept. The overall gameplay interface is easy to understand, making it suitable for even newer players. Next, the Bonanza slot game features up to 117,649 paylines. This number is higher than the average for most slots, so it is an advantage for players.

Finally, though Bonanza features only two major bonus features, these come with many reward combos that allow you to bag huge wins.

The only significant downside of the Bonanza slot is its difficulty when trying to win huge prizes.

During our test, we couldn’t achieve multipliers on the higher end after over 20 minutes of direct spinning. It is a regular occurrence for high-variance slots. Still, it remains a downside for players, as it can be easy to lose money.

Bonanza Slot Mechanics

In general, Bonanza features the same gameplay elements as other slots. However, the only exception is its unique 6×5 game grid, which is not dominant among online slots. In the standard game, you earn a 50x multiplier when you land five purple gemstone symbols. When landing these same multipliers on the free spin rounds, you stand a better chance of bagging bigger wins. If you’re lucky enough, a mega win can lead you to a prize of up to 10,000x your stake.

Bonanza Slot

You can select your bet amount from the adjustment buttons beneath the grid in the game. The positive and negative signs allow you to set bets between £0.20 to £20, and the spin button is almost identical to those on most Big Time Gaming titles. Some primary symbols in the game are red, green, blue and purple gemstones. Other symbols are As, Qs, Ks, 10s, wilds, gold scatters, etc.

Bonanza Slot Theme

Bonanza slot features a treasure mine Megaways theme with several natural elements. The gameplay occurs on a rocky mine, with two mine entrances above the gameplay grid and other details like a waterfall on the right side of the screen. You can also find a wooden house on the lower left part of the gameplay screen. What makes the theme fun is the occasional changes that occur during gameplay and the numerous treasures available. There are gold symbols, as well as gems of different colours.

The backdrop of the slot plays a significant role in the gameplay, as the graphics add a fun element, coupled with the matching sound effects and animations. Upon spinning for each session, a train above the grid drops new symbols, which appear on the grid, making it seem like a treasure delivery system. The Bonanza slot creates a unique experience that adds to your overall gaming entertainment.

Bonanza Slot RTP & Volatility

The RTP, or return to player, represents the amount of money a player is likely to get in return for placing bets on a particular slot. Of course, it’s not a metric that guarantees profit for players. However, it does indicate how much you will get if you are lucky enough as a player. On average, the RTP of most slots falls between the 90-95% range.

However, as for Bonanza, the numbers are a bit higher, as the slot features an RTP range, often around 95% to 96% depending on the game mode.

This is one of the high volatility slots, so remember that the occurrence of colossal payout combos is less frequent.

Bonanza Slot Bonus Features

Unlike some slots with numerous bonus features, the Bonanza slot supports only two major features; the free spin and cascading reels. In this section, we’ll explore these features and their functions during gameplay.

Free Spin

You trigger the free spin feature in the Bonanza slot game when you land the G, O, L, and D symbols on the gameplay grid. This ‘gold scatter’ combo gives you 12 free spins, with a chance to receive an additional five free spins for every other extra gold scatter symbol you receive. The process is unlimited, so if you are lucky enough, you can accumulate several free spins and unlock the cascading reels feature along the line.

Cascading Reels

The cascading reels emerge when you land a winning combo on the slot. After each session, the winning combos explode, and the cascading reels feature replaces them with new symbols, giving you a chance to start a unique winning combination. If you land a winning combo with the new symbols, the feature explodes them again and fills the spaces with new symbols for another winning chance. Depending on your luck, the cascading reels can turn into a winning loop, giving you several wins in a row.

Tips & Tricks For Playing the Slot Bonanza

Though playing Bonanza slot online is straightforward, you still need guidance to maximise your overall winning potential. Thus, we’ve outlined the necessary tips to follow while playing the Bonanza slot. Below are 3 most valuable tips:

  1. Utilise the Bonanza slot free play mode
  2. Stake Wisely
  3. Understand how slot variance works

Utilise The Bonanza Slot Free Play Mode

Free-play modes are helpful for gamblers who love playing slots, as they allow you to practice before betting for real money. To maximise your chances of winning while playing Bonanza, you should familiarise yourself with the slot.

You can access the Bonanza slot demo at any supported casino site, and you do not need to log in to access these free editions in most cases. Of course, slots are luck-based, so the practice would do little. However, it can allow you to understand better how to use bonus features to your advantage and place your next stake according to the outcome of each draw.

Stake Wisely

One of the essential tips for playing slots is to bet wisely. While playing the Bonanza slot game, always bet using only the amount you can afford to lose. Regardless of the payout promised by the game, do not place stakes above your budget, and always make sure you use deposit limiters and other responsible gambling tools where necessary.

Slots can be overwhelming, so you could easily lose track of your gaming sessions. Thus, you are better off funding your casino account with the exact amounts you intend to use for each gaming session. Also, remember to utilise bonuses if available, and watch out for the wagering requirements and other rules to ensure you are on the right path.

Understand How Slot Variance Works

You need to understand everything about a game to get the most out of it. In the case of the Bonanza slot, you have to understand the volatility of the slot so that you can use the right betting strategies for your gaming sessions. A low-variance slot pays out more often during gameplay, but the payouts are usually small. At the same time, medium slots offer balanced gameplay, while high-variance slots pay high but less often.

The Bonanza slot is a medium to high-variance, so you can expect balanced gameplay while playing the base game. However, landing huge payout multipliers takes a lot of work, so the best strategy would be to split your bets into smaller units when aiming for the bigger jackpots.

Our Verdict

The Bonanza slot boasts two major highlights: a mixture of exciting elements and high payouts, featuring huge multipliers and numerous paylines. Our tests on various smartphones revealed excellent compatibility, giving the game an edge over many others. The incorporation of entertaining elements, such as fun adventures, ensures an exciting gameplay experience. Additionally, the bonus features proved to be beneficial. While there may be better slots available, Big Time Gaming still managed to do an impressive job with the Bonanza slot.

Below are some of the most asked questions about the Bonanza slot.

What is the highest amount I can win on the Bonanza slot?

The Bonanza slot allows a maximum bet of £20 and top winning multipliers up to 10,000x your stake. Thus, the highest payout possible in the slot is £200,000.

How often do the bonus features trigger the Bonanza slot?

Through our tests, we landed the free spins bonus feature after about 5 minutes of playing the free game and subsequent times during the gaming session. However, this test is not a benchmark to identify the exact timeframe for bonus features, as slots are unpredictable. Thus, no stamped factor can determine how often you’ll trigger the bonus features in a gaming session.

How many paylines are in the Bonanza slot?

There are 117,649 paylines on the Bonanza slot, which is above the average for online slots and highly beneficial to players.
