Booster Slot Machine

Booster is iSoftBet’s slot machine and a game that has a classic theme, though with a bit of inspiration from the stars. Given the nature of the slot’s theme and the kind of symbols which it uses, it falls to the features and to other areas to make the game attractive for most players. I’m not sure that it entirely succeeds, but I’d mention the features that are available, including the free spins with multipliers, the scatter symbols, wilds and the bonus games that can deliver big payouts. Rewards that get up to $20,000 are a possibility, though only during the free spins. The slot’s 5 reels are getting 25 fixed lines for each round.

Betting and Prizes

Placing a bet shouldn’t be a chore in a slot machine, so I’m glad that iSoftBet didn’t overcomplicate the system that they’re using. They don’t even give you the option to change the number of active lines, so you have to keep them active and you multiply the line bet by 25. That line bet has only 7 possible values, ranging from $0.01 to $2. You can spend up to $50 if you can afford it, but you can also get away with a wager as small as $0.25.

The best payout that you can get from Booster will be the one coming via the Diamond symbol, which promises a reward of 2,000 coins in the base game, worth at most $4,000. Since there are certain free spins where the multipliers get up to 5x, the jackpot can be increased as well, getting it to $20,000 at that point.

Booster Slot Features

You will not find a lot of options in the feature section of Booster. The game has the Bonus symbol to show off in that area, the one that has a logo and a lightning bolt behind it. This is considered a scatter symbol, and the result is that you may use these symbols for their designated purpose without caring what their exact location is. As long as you have 3, 4 or 5 bonus symbols in view, the game will deliver you to the bonus game and its new screen.

The exact outcome of the bonus game will depend on your luck. There are cash prizes and free spins to be won through it. You might get a direct reward, one as high as 6,000 coins, or you might get one of the variants of free spins.

Should you get the free spins, you can have as many as 50 of those to go through, or as few as 5, and with different multipliers. Multipliers attached to the free spins range from 1x to 5x, and all wins obtained during those rounds will be influenced by these numbers. You can’t retrigger the bonus game during the free spins. The Bonus symbols are used as payout triggers during free spins, offering up to 30x total bet.

Theme & Design

While I wouldn’t call the theme idea that they used for Booster interesting, it has its appeal for players that love older games. The symbols are classic one for the most part, so you get three types of Bar logos that are stacked, plus gold stars, two types of 7s and diamonds. The bonus symbol is the only one out of the ordinary here.

Conclusion

Booster is not a great game, but it’s got a decent average RTP, so you’re not going to lose much by giving it a shot.
