Solar Se7en Slot Machine

We’re blasting off into deep space on the Solar Se7en slot machine from Playtech. However, rather than discovering secrets of the universe from the alien landscape players arrive at, we’re instead hunting for riches!

Solar Se7en is played over a five by four grid and features a total of 40 fixed win lines. The slot might offer just one special bonus mode, but it is a really good one. We particularly enjoyed how it was relevant to the interstellar space travel theme.

Unfortunately, lacking a second exciting feature definitely feels like a missed trick by Playtech. After designing such a lush alien world, we could at least encounter some extra-terrestrials up close and personal!

Read on to find out if this slot is out-of-this-world or best left in the furthest corner of the universe!

Pay Lines:40
Max Win:800x line bet
Wild:“Wild” and Spaceship symbols
Our Rating:3.5 / 5


  • Visually appealing. The alien landscape that forms the backdrop for the action is stylish and gives the title a cosmic and cool feel.
  • Innovative bonus feature. We really liked what the Supernova Spins mode adds to the title’s gameplay.


  • Limited bonus features. We really enjoyed the Supernova Spins mode but felt that it alone was not enough to award this slot a truly stellar rating.

Top Jackpots

The top jackpots on the Solar Se7en slot machine are each awarded for matching five of the same symbols along one of the 40 win lines. These high value symbols are each represented by characters and items found on the deep space quest players are invited upon.

We’ve listed the prizes for each five-of-a-kind combination below:

  • Lucky 7 = 800x the line bet.
  • “Wild” = 800x the line bet.
  • Human astronaut = 200x the line bet.
  • Alien man = 150x the line bet.
  • Alien beast = 100x the line bet.
  • Triangular portal = 80x the line bet.

Game Features

Supernova Spins

In the Supernova Spins mode, players are given the chance to re-spin in deep space for stratospheric wins! During the special feature, all spaceships that land on the reels will remain in position and act as shifting “wild” symbols.

Every spaceship that lands will award three Supernova Spins. More spaceships can land during the feature too. This adds more to the re-spin counter at the bottom of the reels!

The spaceships will remain on the reels for all Supernova Spins. They can shift up or down to any position on a reel. They also land in blocks that are two symbols high, making for even greater chances to win.

Regular Symbols

In addition to the higher value symbols on the Solar Se7en slot machine, there are also those that don’t pay quite so well. These are represented by bizarre looking alien fruits and their bright colouration helps to give the slot a strong visual presence.

Below, you’ll find the prizes for matching five of these symbols along one of the 40 win lines:

  • All space fruits = 40x the line bet.

Betting Limits

The number of win lines is fixed at 40 on the Solar Se7en slot machine. This means that players can only adjust the total amount bet per spin. Here, the minimum amount is just 40p – equating to 1p bet per line. Meanwhile, the maximum is £500. When divided by the 40 win lines, this is the same as betting £12.50 on each line.

With such a large upper betting limit, we feel that players of all sized bank rolls will feel included on Solar Se7en. Very few players want to bet more than £500 per spin on slots and those that do probably take a private jet to Vegas to do their gambling!

Overall Rating

Solar Se7enTo conclude, the Solar Se7en slot machine is a decent enough game for a quick punt. In terms of its visual presentation, it looks great. We particularly enjoyed the bright colour scheme and bizarre creature and fruit images throughout. The game also offers a rather large upper betting limit and decent return-to-player rating. These two facts make it ideal for those wanting to wage through a large bonus without losing too much of it.

That said, the slot is not perfect. Its main downfall is that there is just a single bonus feature. Although the Supernova Spin mode is undoubtedly entertaining, it is unlikely to keep players sufficiently engaged on repeat visits. For that reason, we recommend giving Solar Se7en a chance but we wouldn’t blame you for not coming back to it on subsequent sessions.

This game has a rating of 4 / 5 with 459 total reviews by .
