Boost It theme and graphics

Boost It has a unique look and feel, thanks to the Art Deco styled symbols against a jazz era backdrop. In fact, this game's an absolute stunner and more visually rewarding than a lot of slots around. It’s a very clever take on a traditional Vegas fruity, but with real visual sophistication and flair.

STHML has completely rethought the way classic slots should look. Instead of bright and garish colors and bleeps and bloops, it’s given us a smooth and sophisticated jazz soundtrack and some really superb artwork. The symbols on the reels are all recognisable from any 3 reeler. but here they’ve been given a polished makeover. Even the whirring of the reels and the sassy trumpet blare when the stacked wilds arrive rethink the classic stuff in a clever new way.

The Shamrock, Cherry, Bar, 7 and Diamond plus the J, Q, K and A all look as though they’ve been crafted from cloisonné, an enameling technique popular in the Art Deco period. Each symbol has a 3D look and the jewel bright colors, paired with subtle gold, look sensational. The gold and black backdrop is also pure Deco, reminding us of the stunning Chrysler Building in NYC - for totally rebooting this genre, the designers at STHML deserve a huge pat on the back.

How to play Boost It slots

Boost It offers players a range of bets between 25p and £100. Because this is a 243 ways to win slot, there are no paylines to bet on, so your stake is fixed per spin. The extremely clean and user friendly layout of this slot makes choosing player options a breeze. Simply click on an icon to access paytable information or set your autoplay options. You can also toggle the sound on and off, but why would you want to?

When you’ve configured the game to suit your playing style, whether you’re a casual player or a high roller, hit the central spin button to start playing.

Boost It payout ratio and volatility

Boost It has a very enticing theoretical RTP of 97%, which makes it well worth playing. This represents the average payout ratio you could expect from a wager of £100, but this figure can definitely go up or down depending on the RNGs.

Slots from this developer are generally medium to high volatility and this slot is no different. There’s no separate bonus game or free spins to boost your payroll, just the modifiers - and when they hit, especially in combination, you can land some massive wins. But there are dry spells between the big payouts.

How to win at Boost It slots

Unlike a 5 reel slot with a series of paylines, Boost It is a 243 ways to win slot. That means winning combinations are created when symbols land on adjacent reels rather than designated paylines on the 5x3 grid. These always read left to right and it's the possibility of landing 5 adjacent symbols that gives the player 243 ways to win or 3x3x3x3x3.

The highest paying symbol is the diamond, which carries a 20x multiplier. Below that, the multipliers are definitely in single figures but the frequent modifiers that land on the bonus reel give plenty of opportunity to boost those wins significantly. This slot obligingly lets you know the paytable rewards whatever your stake and of course, the higher the bet, the bigger the return in any slot that uses multiplier rewards.

Boost It bonus features

Unlike either a classic Vegas slot or a 5 reel video slot, Boost It doesn’t depend on bonus features like wheels of fortune, pick and win or free spins to generate the really lucrative payouts. Instead, this slot uses the booster reel mechanism to deliver the big wins. This reel lies horizontally on top of the 5x3 grid and spins as the game reels spin, delivering up to 3 game modifiers a time.

There are 4 booster features and 2 wild symbols. The boosters are:

Random wilds: this feature is symbolised by two crossing horizontal arrows and adds up to 3 wild symbols anywhere on reels 2 to 5. Each wild substitutes for all other symbols.

Reel wilds: when the up and down arrow wild appears in the booster reel, look for the expanded wild symbol to land on any reel from 2 to 5. This symbol stacks 3 high and also substitutes for all other symbols.

Symbol multipliers 5x: these will multiply winning combinations involving the chosen symbol by 5x.

Win multipliers: a random multiplier between 2x and 10x will multiply all winning combinations on the reels.

The wild symbol is an intricate gold Art Deco design with the word Wild across the center in silver. These appear randomly as single symbols or stacked 3 high, depending on the modifier shown on the booster reel.

Max-win 8,100x

Volatility Medium

Top RTP 97%

Boost It top win

The top win in the base game is a 20x multiplier for landing 5 diamonds on adjacent reels. But create a combination of 3 modifier symbols on the booster reel and who knows what you might win?

We found it was lightning fast on a smartphone and looked superb - all the detail in the graphics really shines on an HD screen or better yet, a Super AMOLED display.

Boost It free play review

STHML Gaming has a reputation for putting a unique spin on basic gameplay elements to create stunning slots and they’ve done it again with Boost It. The idea is simple - the booster reel at the top of the screen spins up a series of modifiers that can significantly boost your winnings. There are four to choose from and they can spin up in random combinations of 1, 2 or 3 boosters. With a top bet of £100 a spin, that opens the gateway to some very lucrative payouts.

We absolutely love the look and feel of this slot - the backdrop is pure Chrysler building, while the symbols are lovingly rendered like a flapper’s jewels. Score a big win and fireworks worthy of a Gatsby party explode across your screen. Add in the cool jazz soundtrack and this slot is eminently playable and incredibly enjoyable - there may be no breakout bonus features, but this slot is such a feast for the eyes and the gameplay is so exciting that you’ll want to keep spinning and winning.

If you enjoy Boost It, you’ll love…

Any of the STHML slots are well worth a spin - we particularly loved Van Gogh, with its gorgeous graphics and clever bonuses involving collecting colors for game modifiers.
