Booster Slot

General Overview

Booster is an iSoftBet powered 25-line online slotthat’s available since June 2017. Other than its planetary theme, it’s made to be highly gripping for its very high hit frequency of more than 50%. This means wins come up on almost every second spin, often bigger than the total wager itself. To mix it up, the developer also added a bonus that can produce more coins instantly or for the duration of free games, with an added win multiplier. If all is right, then according to iSoftBet this is a game that players will rush to add to favourites, for the long-playing sessions and  low to medium volatility maths model. More on that in the full Booster review below.

Features and Bets

Booster is made for both desktop and mobile, and in both cases the total wager can be adjusted with the coin value. Although the denominations differ by currency, they usually range between 0.01 and 1 credits.

As far as additional settings go, then this 5-reel game plays at a fast pace by default and comes with a more advanced autoplay mode that allows for hands-free gameplay with custom limits for insurance.

Symbols and Bonuses

The intergalactic slot has 7 stacked standard symbols that include classic fruit machine icons like BARs, stars, 7’s and diamonds. They pay for 3 of a kind at least, and from the leftmost reel only. To give you an idea of the variance, the maximum payout for all of them ranges between 25 and 2,000 coins.

Although the hit frequency is among the highest of all online slots, there are no Wild symbols. Instead, the team added Bonuses, which appear on all reels and trigger a second-screen feature for 3 or more that come up in one turn.

On success, you’ll be first taken to a board with various rewards. This includes instant prizes like 6,000 coins, as well as something more fun like 15 Free Spins or Free Spins with an x2, x3 or x5 multiplier. There’s also a mystery prize that remains a secret.

As the coin reward is self-explanatory, the Free Spins bonus offers no significant advantages and cannot be re-triggered. All it does differently than the base game is transform the Bonus icon into a high-paying Scatter, which costs between 2x and 30x your total bet, depending how many specials you get at once.


Booster is a 25-line and 5-reel slot that iSoftBet launched in June 2017. With the hit rate set above 50%, it promises to be players’ favourite for its longer playing sessions, coupled with stacked symbols and a bonus game with instant wins, free spins and multipliers.
