Booster RTP and Volatility

Booster has got an RTP rate of 97.2% and medium to low volatility.
We were more than pleasantly surprised to find out about the perfect combination of the RTP and volatility of Booster. With such a decent ratio, this video slot is truly capable of boosting your stake. However, don’t forget that these factors are only theoretical and tend to fluctuate depending on the active bonus feature. Be aware of the dead spins.

Theme

8.5 

Booster is a beautifully designed slot machine that is, on top of it, very easy to figure out. The visual quality of the interface remains on top regardless of the device you’re using to play, and smooth background music only adds to the general atmosphere. Although it’s a classic slot machine with no outstanding concept, the idea is implemented skilfully. As you spin the slot, you can get distracted by the animations of starts that are slowly flowing in the space just behind the transparent reels. Besides, some minor neon accents make the game even more bright but not too overwhelming.

The regular paytable in Booster includes 3 BAR symbols, a golden star, and 2 Sevens, blue and red. Besides, there is a valuable multicolored diamond symbol, capable of giving out up to 200x your total stake!

The exclusive Bonus symbols in Booster will activate the Bonus Game in case you get a winning combo of 3, 4, or 5 of these symbols anywhere on the reels.
