Space Miners plunges players into an intergalactic mining operation on a remote asteroid, brought to life by quirky, cube-shaped alien miners. [1, 3, 5] The visual design is exceptionally agreeable, with a background of nebular gases as the universe cycles through destruction and regeneration, creating an immersive cosmic atmosphere. [3] The 6-reel grid, initially 3 rows high, is surrounded by cubes of rock and floating aliens. Graphics are crisp and detailed, showcasing colorful square aliens with a variety of teeth and eyes. [2, 3] Animations are fluid, especially when winning symbols explode and Power Up features blast away blockers, expanding the play area dramatically. [1, 4] This classic slot perfectly blends sci-fi with innovative mechanics.

A gentle electronic theme plays in the background, subtly complementing the space exploration theme. [2, 3] The overall presentation ensures an engaging casino game experience. [1, 2]

  • Regular Symbols: Lower-value symbols are four colorful crystal gems (yellow, pink, green, blue). [2, 3, 8] Higher-value symbols are five distinct alien characters (blue, pink, green, orange, red), with the red alien being the most valuable, offering up to 5x your bet for six of a kind. [2, 3, 5, 8, 11]
  • Special Symbols:
    • Wild Symbol: A crystal box (or cart filled with crystals) with the word “WILD” stamped on it acts as the Wild. [1, 4, 10] It expands to cover all unblocked positions on the reel when it lands, substituting for any regular symbol to create wins. [1, 2, 3, 10] Wilds do not hold a value of their own. [1]
    • Blockers & Power Ups: The initial 6×3 grid is surrounded by stone “blocker” tiles. [1, 3, 7] Some blockers contain red-marked Power Up symbols (Cross, Horizontal, Vertical, 3×3). [1, 3, 4] Destroying a blocker with a Power Up triggers its effect, blasting away other blockers in specific patterns, revealing more rows and increasing ways to win. [1, 3, 4, 5]
    • Bonus Scatter: A UFO or Spaceship symbol serves as the Scatter. [2, 3, 8, 10] Collecting 3 or more of these in one game round triggers the Free Spins round. [2, 3, 8]

To embark on your cosmic mining mission in this exciting casino game, first select your desired bet size, ranging from $0.10 to $20 per spin. [1, 3, 5, 8, 11] The game starts with a 6-reel, 3-row grid, offering 729 ways to win. [1, 3, 7, 8, 11] Wins are formed by landing 3 or more matching symbols on adjacent reels, starting from the leftmost one. [2, 7, 8] When you land a winner, the symbols explode, and adjacent blocker tiles are destroyed, triggering a respin. [1, 2, 3, 8, 11] This expands the active play area, revealing more rows and increasing the ways to win. This process repeats with respins until no new wins appear, potentially unlocking up to 10 rows and a staggering 1,000,000 ways to win. [1, 2, 3, 4, 7, 8, 11] In the base game, the grid returns to its 6×3 size on a non-winning respin. [3] We highly recommend trying the Space Miners free slot machine demo mode available on our site to familiarize yourself with its unique expanding grid, Power Up features, and Free Spins mechanics without any financial risk. [1, 2, 3] This mobile slot is fully optimized for all devices, ensuring a seamless and thrilling gaming experience on the go. [3, 4] Blast off and explore the galaxy for stellar prizes today!

Space Miners is packed with dynamic bonus features designed to help you unearth colossal rewards: [1, 2]

  • Expanding Grid & Respins: Winning combinations destroy adjacent blocker tiles and trigger respins. This expands the active play area, revealing more symbols and increasing the ways to win. The grid can grow from 6×3 (729 ways) up to 6×10 (1,000,000 ways to win). [1, 2, 3, 7, 8, 11] In the base game, the grid resets after respins, but in Free Spins, removed blockers remain open. [1, 3, 7]
  • Power Up Features: Some blocker tiles contain special Power Up symbols. Destroying these blockers activates their unique effects: [1, 2, 3, 4]
    • Cross: Destroys all blockers in both a horizontal and vertical direction. [1, 3, 4]
    • Horizontal: Destroys all blockers in the horizontal direction only. [1, 3, 4]
    • Vertical: Destroys all blockers in the vertical direction only. [1, 3, 4]
    • 3×3: Destroys all blockers in a 3×3 area. [1, 3, 4]
    Every normal spin features two Power Ups, while every Free Spin starts with four. [1]
  • Free Spins: Collecting 3 Bonus Scatter symbols (UFOs/Spaceships) in one game round awards 6 free spins. [1, 2, 3, 8] Each additional Scatter awards +2 extra spins on top of that. [1, 3, 8] When bonus symbols land during the feature, you get +1 free spin per Scatter. [3] The key difference from the base game is that Blocker tiles are permanently destroyed when removed, meaning the grid never resets during the feature, making it easier to reach the maxed-out grid. [1, 3]
  • Bonus Buy (Not for UK players): Where available, players can buy their way straight to free spins for the cost of 100x their bet. [1, 3, 6, 9] This also increases the RTP to 97.14%, offering a potentially more favorable high RTP slot experience. [1, 3, 6, 8, 9]

Space Miners features a default RTP (Return to Player) of 96.47%, which is considered a solid and above-average return for an online slot. [1, 2, 3, 4, 5, 6, 7, 8, 9, 11] This makes it a favorable high RTP slot choice for casino games. [1, 9] When utilizing the Bonus Buy feature (where available), the RTP is further boosted to 97.14%, offering an even more favorable long-term return. [1, 3, 6, 8, 9]

The game operates with High volatility (rated 5/5 on Relax’s own volatility scale). [1, 2, 3, 4, 5, 6, 7, 8, 9, 11] This indicates that while wins may not occur very frequently, when they do, they have the potential to be very substantial, with a max win of 50,000x your stake. [1, 2, 3, 4, 5, 6, 8, 9] High volatility slots are particularly appealing to players who enjoy the thrill of significant payouts and are prepared for longer periods between returns. [1, 2, 3, 6, 8] With a hit frequency of 20.18%, meaning a win occurs approximately once every 4.95 spins, it offers a challenging but potentially very rewarding casino game experience. [1, 2, 8]


Space Miners is an exceptional casino game that brilliantly combines an imaginative space mining theme with innovative slot mechanics. Relax Gaming has delivered a visually impressive and feature-rich classic slot where the expanding grid, blocker-destroying Power Ups, and cascading wins create dynamic gameplay. [1, 2, 4, 5] The high volatility ensures a challenging yet rewarding ride, and the impressive 50,000x max win potential makes it a compelling choice for players who appreciate intricate bonus features and high-stakes action in a mobile slot. [1, 2, 8] It’s a highly appealing grid slot experience! [1, 3]
