Space Miners Online Slot Review

Play the Space Miners slot from Relax Gaming and you can unlock up to 1,000,000 ways to win across the 6 reels. It’s a cartoon style game, that you can play on PCs and mobile, and where colourful aliens trigger respins on each win. Expanding wild symbols help to complete extra combinations, and special modifiers will open up the symbol grid even further.

Trigger a free spins feature and it gets easier to max out the number of ways to win, leading to out of this world wins of 50,000x your bet. With average returns of 96.47%, and a high volatility, you can be sure of exciting gameplay from the Space Miners slot machine.

How to Play the Space Miners Slot Game

Square-shaped blue, orange, green, and red aliens grin, sneer, or snarl at you from the reels. These adorable critters appear along with colourful crystals against the backdrop of an asteroid floating in the depths of space. There are some nice animations as the bug-eyed aliens blink, look around, and watch flying saucers zip across the reels.

The first thing you will notice is that active symbols fill just 3 rows, and stone-effect blocks fill another 4 rows above and 3 below. Don’t worry, as with a little luck, aliens and crystals will soon pack the grid.

You can play the Space Miners slot machine on iOS, Android, or Windows mobiles, as well as on PCs, for between 0.10 and 20.00 at the top online slots sites. Just tap the coin symbol on the controls and use Plus or Minus tabs to select a level in seconds.

Other control buttons include the single arrow that starts an Autoplay feature, and double arrows that turbocharge the gameplay. Three small lines on the controls take you to the Space Miners paytable. This has all the details on how the expanding reels system works, and how much you win from the various symbols when you match them on any row, on adjacent reels from the left.

The snaggle-toothed red alien is the most valuable of all and returns 5x your bet when it lands on all reels.

Free Spins & Other Features of the Space Miners Slot Machine

A box of crystals is a wild symbol that can step in for others if it can complete a combination or extend a win across more reels for a higher prize. Central to the Space Miners gameplay is the expanding reels mechanism.

It works like this – every time you get a winning combination, any ‘blocker’ positions connected to a winning symbol will explode. All symbols then vanish, and new ones drop down to fill the newly expanded reels. This gives you more ways to win and makes it easier to expand the active part of the game even further with more respins.

Some blockers have special Power Up features. The Cross destroys blockers in horizontal and vertical lines, while the Horizontal and Vertical Power Ups blast away blockers in a single direction. The 3x3 Power Up feature clears 3 connected rows of blockers across 3 adjacent reels.

Clear the whole grid and you have 10 rows of symbols, for 1,000,000 ways to win. Once a non-winning combination of symbols appears, the respins end and the reels revert back to 3 active rows.

If a UFO bonus symbol appears at any point during a series of respins, it flies off into a collection meter. A total of 3 UFO’s will award 6 free spins at the end of the respins, with any additional symbols adding 2 extra spins to the round. You get 1 further spin each time a flying saucer lands in the round, and once a blocker symbol is destroyed, the position remains active for any remaining free games.
