Is Booster Slot the Right Game for You?

Classic slots always offer a pure slot experience. There are no features to track, symbols to learn, or rules that are too complex. You simply try to land the same symbols side by side and hope to trigger the bonus feature at some point. If this experience sounds good to you, the Booster video slot is the game you should play. We also recommend this game to beginners due to its simplicity and satisfying payouts. And if you like the experience, you should check out the Wild Wishes slot game too: it is very similar.

What to Expect from the Booster Slot Game?

The Booster slot game offers nice graphics but don’t expect amazing effects and animations. After all, this is the classic slots experience. There is no specific theme, but we can say that the game resembles the good old fruit machines with its symbols. Other than the mini-game that can award multiplier, Free Spins and cash prizes, the game has no unique bonus feature.

Bonus Features of Booster Video Slot

There is only one special symbol in the base game: bonus. Booster game does not include Wild or Scatter symbols. Landing 3, 4, or 5 bonus symbols anywhere on the screen during the base game will start the bonus feature.

• The bonus feature is designed as a mini-game, and you can win one of the following prizes:
  • 6,000 coins
  • 5 Free Spins & 5x multiplier
  • 10 Free Spins & 2x multiplier
  • 10 Free Spins & 3x multiplier
  • 50 Free Spins & 2x multiplier
  • 15 Free Spins
  • 100 Free Spins
  • Random mystery reward
• If you win multiplier and Free Spins (any of the multipliers and Free Spins listed above), the bonus symbol will act like Scatter during the feature and start to pay multipliers, no matter where it lands on the screen. 3, 4, and 5 bonus symbols will pay 2x, 15x, and 30x total bet, respectively.
• However, you cannot re-trigger the Free Spins bonus during the feature.

Booster Slot Game Payouts and Big Wins

The betting range of the game is flexible and can suit any budget. The minimum bet value is set at 0.25 coins. And the maximum bet amount is 25 coins per spin. The maximum payout in a single spin is 6,000 coins, but you can win much more than this amount during the Free Spins bonus because of the multipliers.

Paytable

Whether you play real money or the slot demo game, the paytable is fixed. The winnings are calculated by multiplying the values from the paytable by the coin value. However, as mentioned above, this online video slot has multiplier Free Spins, so it would be best to play with the maximum bet value.

(*) This symbol also pays 5 coins even if you land only two.

RTP & Volatility

You can play Booster video slot with an RTP percentage of 97.40%, which is well above the average. The game does not have official volatility info, but based on the paytable and our experience, we can say that the Booster video slot is a low volatility game.
