WinStar was released in 2018 with big expectations, given the casino is technically a spin off of the huge land-based WinStar World Casino and Resort in Oklahoma.

About Booster Slot Game
Despite having a futuristic, sci-fi theme, Booster is quite old-fashioned in how it looks and its gameplay. The graphics are fairly simple with the moving stars in the background being the most advanced element. Old-school fruit machine fans will love the game's classic symbols, including BARs and lucky 7s. Excluding the scatter, there are actually only seven different symbols on the reels – the most lucrative of which is the diamond, paying out 2000 coins for landing five on a payline. The diamond is also the only symbol that pays out for landing two symbols, even if it is only five coins. The single, double and treble bars are the lowest value symbols.
All 25 paylines are permanently enabled and there are 25 coins in play. All you have to do is choose your coin value between 1p and £1, a minimum bet of 25p and a maximum of £25. The gameplay moves along pretty quickly and a little jingle accompanies each win, with the winning symbols lit up. There's also an Auto Spin function allowing you to run between five and 100 automatic spins. You can set the Auto Spin to stop when you reach a certain loss or win limit.
Booster Slot Features, Specials and Symbols
We said that Booster is a simple online slot machine and it’s pretty straightforward when it comes to features too. Unlike most slot titles, Booster doesn't feature a wild symbol, so the scatter is the only bonus symbol in the game. The scatter (a lightning bolt with the word BONUS underneath) doesn't pay out itself, but landing three or more of them anywhere in view triggers the Bonus Game. In this feature, players are offered a variety of different prizes. You simply have to press a stopper and the light will land on your prize. This is what you can win:
- A 6,000-coin instant win
- 15 free spins
- 100 free spins
- Five 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
During free spins, the feature cannot be retriggered but instead, the bonus symbol will pay out as a scatter with three symbols awarding you with 2x your total bet, four getting you 15x your total bet and five scooping you a prize worth 30x your total bet – that’s a top potential prize of £750 when playing at the maximum bet amount. For those who like simple, old-fashioned, fruity online slots, Booster is definitely a game worth jumping on. Let's have lift off!
Try again, luck will be with you next time.
