Big Bonus Booster Review

Big Bonus Booster is a deluxe version of the iconic slot released by Inspired Gaming in 2020 that has charmed so many players. Big Bonus is a medium volatile machine just like the new game with RNG algorithms verified by GLI and under licenses issued by the gambling authorities of the UK, Malta, and Gibraltar.

The Big Bonus Booster slot comes with a classic gambling theme and lots of authentic symbols on the grid, like juicy fruits, multicolored big sevens, and crowns. It utilizes HTML5 technology and is fully compatible with various mobile devices (Android & iOS) and browsers (Safari, Opera, Edge, Chrome, etc.).

Inspired Gaming is proud of its design crew, and the upgraded version stands out with finest-quality graphics, animations, and sound effects. However, they all remain in the classic segment, so they may look a bit generic for those who are not used to playing such games. Several useful tech features are also at hand - Autoplay, Turbo, Left Hand Mode, etc.

Big Bonus Booster is also loaded with Gamble Games, Fortune Bet, and Bonus Buy, in addition to the innovative “Big Bonus+” mechanics. The wide grid has 6 reels and 4 rows and provides a generous amount of 50 fixed paylins. They all start from the leftmost column and continue to the right on adjacent reel positions.

Wilds land on all reels during the base game and substitute for all regular symbols.

They also pay the most attractive rewards if lined up - from 1x to 25x the bet for 3 to 6. Crowns pay up to 20x, Red Sevens - up to 15x, and Silver and Blue Sevens - up to 10x. Fruits pay different prizes in the range from 0.10x to 8x the wager.

Scatters can also land on any reel, and despite not paying direct cash, if you have at least 3 in view, you'll win no less than 20x the stake. The betting range is wide as usual for the provider - €0.10 up to €200 per spin. This makes the title a suitable match for high rollers and regular gamblers, and thanks to the Big Bonus Booster demo, you can see for yourself without risk.

Bonuses And Special Features

Just like the 2020 original, the Big Bonus Booster game comes with a Free Spins round designed in an attractive way.

The provider has added several helping tools, including the Gamble minigames and Spin Chance, which is rather unique for Inspired slots. Below, you can find more information about all special features:

Gamble Feature

The Gamble tab is located in the upper right corner of your screen or in the Settings menu. You can adjust it to be On, Off, or 5x stake, which means that it will activate for wins equal to or greater than 5 times the bet. Two Wheels are presented, offering a prize increase by 50%, 100%, or 300%, and a Bonus Entry.

You'll see that the bigger the prize, the lower the winning chance, so gamble wisely. If you want to risk for access to the Bonus minigame, you can choose the number of triggering scatters. However, the chance is very slim, so you'll need to offer a huge prize, which is against the logic of usual strategies.

Big Bonus Entry

Scatters are the key to the hefty prizes in this slot machine, and 3, 4, 5, or 6 trigger the Big Bonus Entry. It all starts with a Pick Me round, where you'll be presented 6 to 15 Diamond symbols to choose from. When you select 3 of the same kind, the main bonus minigame will begin.

The Trail represents 5 tiers and 5 possible minimum wins - 20x, 25x, 30x, 50x, and 100x the bet, with the following colors: yellow, green, red, blue, and silver.

If you trigger the bonus with 3 scatters, all will be in play during the Pick Me. If you have 4, 5, or 6 scatters, the possible tiers will be reduced to the 4, 3, and 2 highest-valued prizes.

Free Spins

The Big Bonus Booster Free Spins minigame is unlimited, and reels will spin until a win greater than the current minimum is achieved. The Diamond-symbol progress from the Pick Me round will be saved and transferred to the actual bonus. Colored Diamonds may land on reel 6 and will be added to the Trail.

It will be upgraded until the final segment (100x) is reached. During the Free Spins minigame, any wilds that land will become sticky and will be held in their positions until the end of the feature. However, unlike the base game, they can land on reels 2, 3, 4, and 5 only.

Fortune Bet, Spin Chance & Bonus Buy

The Big Bonus Booster slot may be enhanced with some helping features if they are not restricted by the respective market's regulator.

Bonus Buy is the rarest feature and allows an instant Bonus trigger at a certain price. Fortune Bet increases the base bet by 50%, but also boosts the bonus-activation chance by more than 2 times.

Spin Chance is an automatic feature, which triggers if your current balance is above zero but lower than the selected bet level. You can gamble your remaining balance for another base game spin via the displayed Wheel. A stop in the green segment will award the respective round, while the red will drain the rest of your balance.

Big Bonus Booster RTP, Volatility And Max Win

The Big Bonus Booster RTP rate is 94.50%, which is below the expectations and below the original slot's rate. Actually, Big Bonus has an adjustable payout coefficient, so I would suggest you double-check the rate on every casino switch.

The game is characterized by medium variance, so wins will be balanced most of the time, but periods of drought are also to be expected. The Big Bonus Booster max win is 12,500x the total bet, but no more than the cap set by Inspired Gaming - €250,000.

Big Bonus Booster Demo Version And Free Play

As usual, SlotCatalog provides easy access to free play via a Big Bonus Booster demo link. It's available at the beginning of this guide and will allow you to assess the pros and cons of the titles via your unique prism.

Thus, you can decide whether to continue and risk real money or look for an alternative game!

Similar Slots To Try

Finally, I would like to end my Big Bonus Booster review by suggesting several great alternative slots. Inspired is known for its affinity to premium-quality classic machines, so I will continue with its library. Wild Drop Multiplier has similar volatility and RTP, but also offers 40 lines, Fortune Bet, Gamble, respins, free spins, and symbol swaps.

At the same time, Gold Cherry is more generic, but seasoned players will appreciate the both-way paylines and those lavish wild transformations. You can win big via the Golden Cherry Free Spins played with nice multipliers. The cherry on the cake is 6 Jokers by Pragmatic Play, offering modern Pay Anywhere mechanics, cascading reels, and awesome wild multipliers during the Joker Respins.

Final Thoughts

Inspired Gaming knows how to thrill passionate players, and games like the Big Bonus Booster slot are for those who cherish genuine gambling. The authentic environment mixed with frequent winnings, slot machine tunes, and bonus features is exactly what many seasoned players seek despite the basic design.

Sadly, I found very few upgrades beyond the improved graphics and gameplay. The provider promises a boost, which is minor, in my opinion, but I'm still a fan of those massive 50 lines. Another drawback is the low RTP rate, and hopefully, other versions with more significant payout potentials will be released!
