Booster Slots

Play the Booster video slot for a space-age adventure with a classic slots flavor. This gorgeously designed, low-tech, low volatility game comes from iSoftbet, who are big fans of rebooting a classic slots game for the modern gambler. And they do it with style. 

Following great success with Neon Reels, the team are taking a similar approach. Although design and features are on a more low-key scale, there's still plenty of drama and real cash potential here. 

The Booster video slot offers 25 paylines of simple base game action. Wins are fairly high-frequency, and there's the chance of some fantastic top-end payouts. However, this game's gravity pull comes from one solitary bonus feature with multiple winning possibilities. 

Win big with up to 100 free spins, free spins plus multipliers or just huge coin payouts. Excitement builds as the Booster bonus meter spins to uncover your reward. Moreover, you can reliably expect smooth gameplay and high-quality graphics with software by iSoftbet

This burgeoning company isn't yet among the biggest players in the market – yet being the operative word. Their catalog of slots and games is impressive to say the least, with the list including a number of big branded titles. This, coupled with their increasing affiliations with other industry leaders, means they're making fast inroads into the big leagues. 

We see new releases almost monthly from this prolific team, and the free Booster slot is one of their latest additions. On paper, Booster meets all the criteria for a great online gambling game. We're not satisfied with a few tick boxes, though. 

Read how we set out to thoroughly test this new kid on the block and see exactly what it's like for online gamblers to play.

Play From 0.25 per Spin 

The game's 25 paylines are fixed, with stakes offered from 0.01 to 1.00 – meaning your bet ranges from 0.25 to 25.00. These stakes probably won't attract the high rollers. Mind you, with the low volatility in mind, this game is aimed firmly at a more casual or recreational gambler. 

How much you can expect to get back on your bet is determined by the RTP. Booster’s RTP is impressive at 97.04%, which should give you a good return over time.

Classic Slots in a Galaxy Far, Far Away

A star-filled screen opens up as players are propelled through space at warp speed. The 5x3 reels are see-through and filled with familiar retro slots symbols of bars, stars and 7s. In fact, Booster was slated to be called Mystery 7s before a last-minute name change was issued by the development team.

There are only six symbols on this slot. These often appear stacked and they give this low-tech game its clean, simple lines. Reel spins are accompanied by a percussive, space-age tune. iSoftbet do love their ambient soundtracks, and Booster offers the perfect setting for one.

Payouts at the upper end of the pay table offer some serious prize potential. The blue 7 pays 200 coins for five of a kind. The red 7 boosts up the prizes to 500 coins for a full matching five. The base game's top jackpot, however, comes from five glittering purple diamonds that will award 2000 coins to the lucky winner. 

There's a refreshingly high-frequency hit rate on wins for this low volatility game. There are no wild symbols or scatters, and no further features during base game.

However, there are plenty of thrills when it comes to the game's bonus feature.

Bonus Chances = Massive Wins 

Land between three and five of the lightning flash bonus symbols and this simple, fun game will be propelled into a different dimension. The backdrop turns a deep red and the soundtrack kicks up the gears as the bonus screen comes into play. 

The screen fills up with a nine-square grid, offering eight different bonus options. Hit the central start button to see the squares light up sequentially. Where will they stop? What bonus option will you hit? 

The possibilities are as follows: 5 free spins with 5x multiplier, 10 free spins with 2x multiplier, 10 free spins with 3x multiplier, 15 free spins, 50 free spins with 2x multiplier, 100 free spins or 6000 coins. The Mystery Box option will include any one of these bonuses. 

Players can't retrigger during free spins, but bonus symbols now pay out as scatters. Impressively, three of a kind will pay 30x your total bet. So, with all these options, you can see that there are some really big wins possible from this real cash-boosting bonus round.

Best to Play for Real Money 

iSoftbet's platform means gorgeous high-definition graphics and slick gameplay on all formats, from desktop to smartphone. What’s more, the mobile-optimized game has functions that really suit the touchscreen. 

The simple gameplay and appealing soundtrack make this an easy game to play either for a few quick spins, or for some longer downtime. With its RTP and pay table this promising, the Booster video slot is a super option to play for real money.

More Space-Themed Slots 

As space is the final frontier, there are galaxies of space-themed slots available to play online.  

Games that offer a very similar space-age experience for players include Netent's classic Starburst or iSoftbet's Wisps – both of which feature a simple structure with an ambient atmosphere. These are solid games with appealing graphics that fit into the same category as Booster. 

If you want a more immersive space experience, you should check out Endorphina's intergalactic mission 2027 ISS. Equally, for a brilliant retro ride, Play'n GO's Space Race is unbeatable. 

However, for players who love the thrill of the bonus round, then Novomatic's Red Hot Repeater does a superb job of building anticipation and potentially hitting big. It's another simple, classic base game with all its clout in the bonus action. 

Play the Booster Video Slot Now 

Fans of software by iSoftbet will be on familiar ground with the Booster video slot. Atmosphere and mechanics echo other successful online slots they've produced. So if you're looking for innovation and ground breaking new features, then Booster is not your game. 

If, however, you like high-quality, appealing 3D graphics with low-tech, easy-to-play mechanics, then you're in for a treat. The free Booster slot does what the iSoftbet team know how to do so well. 

It's a gorgeous game with excellent playability that makes a pleasant experience. There's loads of action in the base game's high hit rate. Plus, there are some real thrills from the bonus feature. What's not to like about all of that? 

A great game for mobile and a big hit to play for real money, Booster is definitely a strong addition to the iSoftbet canon.
