Big Bonus Booster Slot Review

Big Bonus Booster by Inspired Gaming brings a lively fruit-themed classic to your screen with 6 reels and 50 paylines. Wilds sub in for all symbols (except the Bonus Scatter) and stick around during Free Spins.

The Big Bonus starts with a pick me round with Multipliers from 20x to 100x. Whatever the outcome of the pick me round, you are guaranteed to win that much from the Big Bonus. Also, you get Sticky Wilds in the Free Spins and the opportunity to upgrade the minimum win value by collecting gems. The Fortune Bet mode ups your chances of triggering the bonus by 50%. You can use the Gamble feature to potentially double or triple your wins or snag a Big Bonus entry.

Even though you aren't guaranteed to win much, it still makes the Free Spins more exciting. I think this is a decent game with a weak math model, so you can try it.

Introducing Big Bonus Booster Online Slot

Big Bonus Booster is a classic themed game in the modern era. This game features 6 reels, 4 rows, and 50 paylines, offering plenty of room for action. The theme might deceive you because this game isn't light on bonuses like a classic game. It is a fun-filled ride with several bonuses, including Free Spins with Sticky Wilds.

This game fits the typical style of Inspired Gaming, which is all about several bonuses and flexibility. It is far from perfect, and we will explore how good it is in this Big Bonus Booster slot review.

Theme & Design: Classic Fruit Charm

Theme and Design

Big Bonus Booster is a throwback to the good old days of fruit machines. You will be greeted by a sea of colourful fruit symbols, all popping nicely against a green backdrop. It's got that polished look you'd expect from a new game but still keeps that fruit machine charm. There's plenty of room for the action to unfold.

Music and Soundtrack

The soundtrack really added to the buzz. It combines the classic slot machine sounds we all know and love with upbeat tunes that keep things interesting without boring you.

Bonus Features

Big Bonus Booster is filled with features which we will explore now.

Big Bonus Entry

Land 3 or more Bonus symbols anywhere on the reels. You'll get to play a pick-me game where you choose tiles to reveal gems. Match 3 gems, and you'll get your starting Big Bonus value, anywhere from 20x to 100x your stake, depending on how many bonus symbols you landed.

Free Spins Feature

The Free Spins in this game are a bit special. Any Wilds you land will stick around until the feature ends, which can lead to some tasty wins. It's got Big Bonus Booster Gems that can bump up your Big Bonus trail for bigger payouts. The Free Spins keep coming until you win at least the current Big Bonus value.

Fortune Bet

Switch on the Fortune Bet mode. It'll cost you 50% more per spin, but it boosts your chances of hitting those bonuses by quite a bit. If you like frequent action, it's worth a shot.

Gamble Feature

After any win, you can choose to gamble. You'll see two wheels, one for cash Multipliers and another for bonus entries. Use the plus and minus arrows to decide how risky you want to be, then give it a spin. You could multiply your win or even bag an entry into the Big Bonus round.

Spin Chance

If you've got anything left in your balance, you'll get a Spin Chance. It's a neat little feature that lets you wager what's left for one more go. Hit 'Play', and if it lands on green, you're back in the game, or you will lose the remaining balance.

Big Bonus Booster offers a top prize of 833x your stake and has an RTP of 94.50%. It's a medium-high volatility game, so you can expect a decent balance of risk and reward. Keep in mind that 94.50% RTP means for every €100 you put in, you can expect about €94.50 back over time.

Big Bonus Booster: A Slot Machine Worth Spinning?

Big Bonus Booster slot is a decent game that could have been much better if it had been more innovative or lucrative. You can find bonuses such as Spin Chance and Fortune Bet in many games by Inspired Gaming. The Free Spins round with Sticky Wilds isn't anything special or new. You can win 100x or a little more during the Free Spins, so the potential isn't that much.

The Big Bonus Booster slot isn't that impressive, but its guaranteed minimum win during the Free Spins and flexibility may appeal to you. In short, it is worth a spin if you don't know what else to play.
