Space Miners is an online slot designed by Relax Gaming. The core features include free spins, power-up symbols, respins, and up to 1,000,000 ways to win. It is a highly volatile slot game with a 96.47% RTP, and the top prize is worth 50,000x your stake.


Space Miners takes you on an intergalactic mining mission with plenty of bonus features to help you on your way. Yet, whereas tech billionaires are planning this type of adventure for humans, Relax Gaming has decided to give the job to a team of aliens – a wise choice.

There are quite a few alien-based slots out there, but Relax has made sure that Space Miners does not have that copy-and-paste feel to it. The graphics, big top prize, bonus features, and power symbols make entertaining gameplay. This slot is bursting with potential, so we’ve done some digging and mining of our own to bring you this Space Miners review.

You can give the Space Miners free play demo a spin right here at Slots Temple.

Theme, Graphics & Soundtrack

The space theme hits a note in this day and age as various tech entrepreneurs continue to look to the stars for the future of humanity. The art of mining asteroids may be some way off yet, so perhaps this is why Relax has given the job to a bunch of aliens.

Theme aside, the game comes complete with impressive graphics and an ethereal soundtrack set in the depths of space, with details of galaxy swirls and alien ships. Be sure to catch the intro movie as well – it gives you a peek into the theme idea.

Alien design can go one of two ways, and Space Miners has rightly opted for the fun and charming path - much akin to the likes of Reactoonz or Cluster Slide.

How to Win

Space Miners is set on a grid that holds a huge number of ways to win. Gameplay starts on a standard 6x3 grid with 729 ways to win, but this can quickly expand up to 10 rows with a staggering 1,000,000 ways to win. Undoubtedly, this is a standout feature but take note it’s only open in the bonus game.

The betting limits in Space Miners are £0.10 and £20 per spin.

Space Miners Power-Up Symbols

The aim of the game in Space Miners is to remove all the blocker tiles and uncover the maximum 6x10 slot grid. The space miner aliens are tasked with this job, but they get some help along the way.

Blocker Tiles

Any winning combination triggers a respin and also removes any linked blocker tiles. When unblocked, these sub-symbol tiles are used for extra symbols during the respin. This process repeats until you max out the grid or you spin zero winning combinations.

How Power Up Symbols Work

Power-up symbols help to make the mining process a little easier. These symbols are embedded in the blocker tiles and become active once revealed through the process explained above.

  • Cross – All blocker tiles are destroyed in a horizontal and vertical line.
  • Vertical – All blocker tiles are destroyed in a vertical line.
  • 3x3 – All blocker tiles are destroyed within a 3x3 area.
  • Horizontal – All blocker tiles are destroyed in a horizontal line.

Free Spins

Collect at least three UFO scatter symbols to activate the free spins bonus game. A total of six spins are available with three scatters, and two extra spins are added with every additional scatter.

During the free spins feature, the one standout rule is that all destroyed blocked tiles stay that way until the end of the spins – meaning the grid does not reset, unlike in the base game.

Additional spins are awarded when you land extra UFO scatter symbols during the feature.

Our Verdict

Space Miners from Relax Gaming may remind you of previous alien-inspired games from the past, but don’t let that put you off playing it. It has a unique charm that helps to set itself apart from others. Plus, the long list of features and top prize of 50,000x your stake certainly helps the playability factor.

You can’t help but think this game has been inspired by recent events linked to space exploration, and for that, we should applaud the team from Relax. The decision to use mining aliens rather than a team of humans put together by Elon Musk or Jeff Bezos is also a wise move that boosts the fun factor.

Fun, Feature-Rich Gameplay

Space Miners is packed full of features, all of which help to enhance your gameplay with every spin. The slot looks and plays exceptionally well, and we believe that Relax has got a winner on its hands here. Come and see what those aliens can dig up for you in our demo version here at Slots Temple.
