Video slots can soon adopt the game. The game comes with advanced gaming options and surprises you with unexpected prizes and attractive combinations of the free spins. There are also numerous playoffs that keep the interest of the players intact.

First Look

When you open the slot you encounter a relatively simple star filled theme. The total bet option opens the betting window. The pay table has the sections that describe the available multipliers, rules of the game, a visual scheme of active lines and Help. There is an Auto Spin option that sets the game into automatic mode. This feature spins the reels automatically for  100 times. The gamer can sit and relax as there are various responsible gaming tools built into it that controls the loss limits of each session. The winnings section shows the total payoffs that are present for a round. The bet section contains the total bet amount. Balance is to check the remaining amount left on you. The credit shows the number of credits in your account. And the winnings is your amount of total win. A 3D slot takes the game to a different level. There are user settings that allow the users to speed up the game and turn the sound on or off.

Pros and Cons

If the player hits the bonus, then the rewards are decent but the bonus feature is however very hard to trigger. Moreover, at higher betting levels the volatility increases. That means only an average stake triggers the bonus game relatively easy. Also, the bonus game by default makes the picks available for the players instead of a transparent free spins feature. As a player, if you are looking for a good back story and a wide range of extras then Booster does not fall under your kitty. It is also not a model for the gamblers who are after interesting characters and highly unusual thematic slots. But if you are looking for a simple fruity action then Booster can be a viable option.


Nonetheless, Booster attracts with its simplicity and clear features. The graphics are classic yet are pretty basic. All in all, if you just want to stop by a fruit machine reboot, hit a few clicks, earn some coins, free spins or free spins with multiplier then Booster is a slot machine to go after.
