Superstar Sevens (Hacksaw Gaming) – Slot Review
Superstar Sevens leans into a bold, modern take on the classic fruit-machine theme, blending retro casino imagery with Hacksaw Gaming’s signature high-energy style. Traditional symbols like sevens, cherries, dice, crowns, and diamonds are presented with flashy neon effects, lightning visuals, and a slick arcade-inspired atmosphere. The overall theme feels like a high-stakes slot showdown, where old-school casino nostalgia is reimagined through aggressive animations, electric visuals, and adrenaline-fuelled sound design.
Superstar Sevens is played on a 6×5 grid using cluster pays for groups of five or more matching symbols. The game sits in the medium-volatility range, offering an RTP of 96.37% and a maximum win of up to 10,000x your stake. Bets range from £0.10 to £100.
Superstar Sevens Symbols & Pay Table
The slot features 14 symbols, including low-paying card ranks (10, J, Q, K and A) and five premium icons in the form of limes, dice, cherries, crowns and diamonds. The Diamond is the highest-paying regular symbol, awarding up to 100x for clusters of 13 or more. Alongside these are Wild, Scatter, Lightning and Epic Lightning symbols, with Wilds substituting for all regular symbols.
Superstar Sevens Features & Mechanics
Winning clusters trigger the Super Cascade feature, removing all matching symbols of the winning type and allowing new symbols to drop into place. All wins during a spin are tracked in the Total Win Bar and paid once the spin fully resolves. If a Lightning symbol lands alongside a win, the Cascade Counter is activated, converting non-winning symbols removed during cascades into additive multipliers. Low-paying symbols add 1x, while high-paying symbols add 2x to the multiplier shown in the Total Win Bar, which is applied to the total win at the end of the spin.
Epic Lightning symbols provide an extra layer of volatility. When one lands and there is a win in the Total Win Bar, it applies an additional multiplicative multiplier at the end of the spin, with possible values ranging from 5x up to 100x. Only one Epic Lightning symbol can land per spin, while landing six Scatter symbols at once instantly awards the maximum win.
The game includes three Free Spins modes. Reel Charge is triggered by three Scatters and awards 10 free spins with a higher chance of Lightning and Epic Lightning symbols. Lucky Strike, activated with four Scatters, builds on this by guaranteeing a Lightning symbol on every spin. The hidden Juicy Joltz bonus is unlocked with five Scatters and features a progressive Total Win Bar that only pays out at the end of the round, although Epic Lightning symbols do not appear in this mode. All bonus rounds allow retriggers via additional Scatters, with Reel Charge and Lucky Strike also available as bonus buys.
Conclusion
Superstar Sevens delivers a fast-paced and explosive slot experience that blends classic casino symbolism with Hacksaw Gaming’s trademark volatility and modern mechanics. The cascading wins, escalating multipliers, and high-impact bonus features create plenty of momentum, especially when lightning modifiers come into play.
