Superstar Sevens Slot (Hacksaw Gaming)

The Superstar Sevens slot is played on a 6x5 grid with Cluster Pays. You need 5 or more matching symbols appearing adjacent to one another to form a winning cluster. Multiple winning clusts can land on the grid simultaneously as the top payout per symbol is awarded for 13 instances.

As with most Hacksaw slots, the minimum bet is 10p a spin. With the maximum bet being £5 a spin (or £2 for under 25s), use the up and down arrows to adjust your stake. Non-UK players can use Autoplay as well as Turbo/Super Turbo modes.

The Superstar Sevens RTP rate is 96.37%, which is above the slots average. You may also find 94.27% and 92.38% RTP versions at your chosen site so check the Paytable.

Medium volatility (3/5), winning clusters will land, on average, every 2.34 spins as the hit frequency rate is 42.64%. Superstar Sevens comes with 10,000 x bet max wins: this can be won in the base game and all bonus features.

With a classic/retro theme, the Superstar Sevens slot takes you back to a retro age of casinos. Using classic casino visuals, the graphics have an arcade feel. Clean and crisp, the soundtrack is a little bizarre and wouldn’t be out of place in a comedy/murder mystery film.

On the grid, you’ll come across low-value A, K, Q, J and 10 royals. The higher-value symbols include lime slices, dice, cherries, a gold crown and diamond: the diamond symbol is the best paying, awarding 100 x your total bet for 13+ in a cluster.

Superstar Sevens benefits from several special symbols. There is a Wild symbol that substitutes for all symbols, as well as a FS Scatter and Lightning symbol.

Superstar Sevens Mobile

With all Hacksaw Gaming titles using HTML5 technology, Superstar Sevens may have a retro feel but it compatible with desktop, mobile and tablet devices. If you opt for a smartphone, it can be played on iOS and Android devices.

The Superstar Sevens slot comes with cascades, a cascade counter that collects multipliers that apply to the total win collected in the Total Win Bar when a Lightning symbol activates it. With an Epic Lightning symbol boosting the total multiplier by up to 100x, there are 3 free spins features with a higher chance of Lightning symbols, guaranteed Lightning symbols and a progressive Total Win Bar.

Super Cascade

When a winning cluster lands, the Super Cascade feature comes into play. All winning symbols are removed from the grid, with new symbols dropping down to fill the empty spaces. This gives you another chance to land a winning cluster, with the process repeating until no new clusters land.

Cascade Counter

The Cascade Counter is activated by landing a Lightning symbol and a winning cluster on the same spin. Then, all removed non-winning symbols transform into a multiplier value. Each collected low-value symbol adds a +1 additive multiplier per winning cluster, with a 2x additive multiplier per winning cluster for high-value symbols.

You can keep track in the Total Win Bar above the grid. Once all wins and super cascades have taken place, the final win will be subject to the multiplier value in the Total Win Bar.

Look out for an Epic Lightning symbol as your total win is subject an extra multiplier of 5x to 100x but only if there is a win in the Total Win Bar.

Free Spins features

Superstar Sevens comes with 3 free spins features, all offering an upgrade on base game play. With all options, you begin with 10 free spins: 2 or 3 FS Scatters will result in 2 or 4 extra free spins, respectively. The details are as follows:

• Reel Charge: Triggered by 3 FS Scatters, you will benefit from an increased chance of Lightning and Epic Lightning symbols.
• Lucky Strike: Triggered by 4 FS Scatters, you are guaranteed a Lightning symbol on every free spin.
• Juicy Joltz: Triggered by 5 FS Scatters, it works like the Lucky Strike free spins but the Total Win Bar is progressive, boosting your chances of big wins.

Rating: 3.4/5

Superstar Sevens is a quirky, retro/arcade style Cluster Pays slot that offers fresh twists on conventional features that can result in up to 10,000 x bet max wins.

Chris Taylor

The Superstar Sevens slot is not a typical Hacksaw Gaming release. Visually, the studio focuses on quirky or horror themes with this retro throwback a pleasant surprise. I’m not quite sure what is going on with the bizarre soundtrack but it works.

Being a Cluster Pays slot, I was expect cascades. I like the way that removed non-winning symbols become a multiplier value (1-2x depending if they’re low or high value) and are added to the Total Win Bar. Activated by the Lightning symbol, the Epic Lightning symbol can add up to 100x to the multiplier if there is a win in the Total Win Bar.

With the 3 free spins features, you benefit from a higher chance of Lightning symbols, guaranteed Lightning symbols and a progressive Total Win Bar. In the Juicy Joltz free spins, all wins are stored and subject to the multiplier at the end of the feature. For reference, the Total Win Bar features in Pray For Three.

Despite the bonus features not being unique, Hacksaw has managed to combine them into a fresh package with Superstar Sevens. With 10,000 x bet max wins, this quirky, retro slot has more to it than meets the eye. Will it be classed as one of Hacksaw’s top games? No, but it’s certainly an option if you like this kind of game.

If you want Cluster Pays slots that break the mould, Push Gaming’s Jammin’ Jars and Print Studios’ Reapers would be my choices. However, I would go for Uncle Profit (also by Print) as it’s cheeky, playful, offers 50,000 x bet max win potential and has a 4.6/5 rating.
