About the Game

Booster is a sci-fi themed game that has players wanting to blast off! Created by iSoftBet, Booster is a 5 reel, 25 payline online video slots game with a bonus feature that can award prizes of up to 6,000 coins.

The player can begin the game with as little as 0.25.

Visually, Booster is a simple game, with a generic space background. The reels themselves are minimalistic, consisting of a slightly darker box with thin white lines separating the reels. The symbols themselves are a mixture of traditional symbols (BAR, Diamond and 7) and specific themed symbols (The Star and Bonus Symbols). In this game, the BAR symbols represent the lowest values, with the single bar representing either 5, 15 or 25 coins depending on how many the player lands. The double bar awards the player 10 coins for 3, 10 coins for 4 and 75 coins for 5. The triple bar awards the player 15 coins for 3, 25 for 4 and 100 coins for 5. The next symbol is the star (20, 50 and 150), followed by the blue seven (25, 75 and 200), the red 7 (30, 100 and 500) and then finally, the diamond. This symbol is different as the player receives a payout even if they only land 2 of these symbols on an active payline. If the player lands 2, they receive 5 coins. 3 symbols equal 50 coins, 4 symbols awards the player 500 coins and 5 symbols awards the player a massive 2,000 coins!

All in all Booster is a great game that was built well. The RTP (Return to player) of the game is 97.4%, which is absolutely huge. The fact that the jackpot is tripled during the bonus round is an interesting feature that is sure to keep players wanting to keep going for the chance to win just that little more. I’d recommend this game to anyone who wants to play a well made slots game, without having to risk breaking the bank too much.
