Visually, Booster is simply done – a star-filled, space backdrop forms the backdrop to the reels. There you’ll see a selection of classic fruity symbols spinning around the reels. You’ll see single, double and treble bars which award payouts of up to 25, 50 or 100 coins per payline. Next come the star at 150x followed by the blue and red 7s which offer payouts of up to 200 and 500 coins respectively. The best of the standard symbols is the diamond – land 2, 3, 4 or 5 of these and you’ll win 5, 50, 500 or 2,000 coins.

The symbol you’ll really be hoping to see is the bonus – land 3, 4 or 5 of these anywhere on the reels on the same spin to trigger the Bonus Game feature. You’ll then be shown a board that offers a variety of potential prizes. Press the stopper – wherever the light lands will be the prize that you’re awarded. On offer are:

  • A 6,000 coin instant win
  • 15 free spins
  • 100 free spins
  • 5 free spins with a 5x multiplier
  • 10 free spins with a 2x multiplier
  • 10 free spins with a 3x multiplier
  • 50 free spins with a 2x multiplier
  • A Mystery Prize

Booster is a very simple game, both in how it looks and how it plays. The graphics are pretty basic which is what you’d expect from most fruit machine re-boots. Everything is clear enough though. The features are straightforward too. Just hit stop and you’ll get a coin win, free spins or free spins with multiplier. It really is as simple as that.

We found the bonus feature quite hard to trigger but there were decent rewards on offer when we did hit it though. We’d put the variance in the medium to high range. This isn’t a slot if you’re after back story and a range of extras. For simple, fruity action it does the job just fine. If you want a more prominent theme, 24 and Paranormal Activity (both by iSoftBet) are good options.
