Super Boost

Super Boost, from London-based developer Electric Elephant, is a galaxy-themed video slot released in September 2020, running on a 5-reel grid with 40 fixed paylines. It's built around a big headline max win figure, though the rest of the package is more understated by comparison.

Theme and gameplay feel

The visuals lean on a faux-galactic setting — simple, glowing symbols, a low-key electronic soundtrack, and a starry night backdrop rather than an elaborate storyline. Each of the five reels fills with five symbols on every spin, and a multiplier ladder sits alongside the reels, climbing as high as x100 during the right feature run. It's a fairly minimal presentation overall, putting the emphasis squarely on the mechanics rather than on visual spectacle.

To land a win, players need at least three adjacent matching symbols starting from the leftmost reel on one of the 40 fixed paylines. Lower-value symbols are royals (10 through Ace), each worth 1.5x the stake for five of a kind, while mid and higher-value symbols are bright geometric shapes worth between 2.5x and 7.5x for a full line. The top-paying Logo Wild pays 30x for five of a kind and substitutes for any other symbol, playing a key role once the bonus features kick in.

What the RTP means for you

Super Boost returns 96.25% to players over time, a solidly above-average figure that adds genuine long-term value on top of its headline win potential.

Volatility and hit frequency

The game is rated high volatility with a relatively low 14.47% hit frequency, meaning players should expect extended stretches without a win between the bigger hits. That pattern is offset by cascading symbols and the progressive multiplier ladder, which can turn a single productive sequence into a much larger payout.

Max win and stakes

Super Boost's standout number is its 17,643x maximum win — a genuinely huge ceiling that puts it among the bigger-swinging slots in its category. Stakes run from 0.10 up to 50 per spin, keeping the entry point accessible despite the high-volatility, high-ceiling design.

Verdict

Super Boost pairs a massive 17,643x max win and a strong RTP with a deliberately understated, minimalist presentation — a slot built for players who care more about mechanics and multiplier potential than visual flair. Given the low hit frequency, it's worth testing the free demo at johnessyslots first to get comfortable with the pacing before playing the Super Boost slot for real money.
