Space Miners Slot Review
Relax Gaming have built their reputation by crafting games that deliver on both visual appeal and mechanical depth. Space Miners, released in February 2022, represents a standout title in their portfolio that combines a space mining theme with innovative grid expansion mechanics. The game arrived at a time when the market was becoming increasingly saturated with Megaways variants, yet Relax Gaming chose a different path—creating something that feels genuinely novel. With a cartoonish alien aesthetic and clever blocker mechanics, Space Miners distinguished itself as a premium high-volatility offering that would prove to be a strong contender for slot of the year recognition.
Base Game & Features
Space Miners operates on a 6-reel grid that starts at 6×3, providing 729 ways to win from the outset. The core mechanic revolves around a tile blocker system—winning combinations destroy blockers in specific patterns, gradually expanding the grid row by row. This expansion can ultimately reach 6×10 with up to 1,000,000 ways to win, fundamentally transforming the game’s potential as you progress. It’s a mechanics-first design that puts agency in the player’s hands through consistent gameplay action.
Power-Ups & Blocker Mechanics
The base game includes four distinct power-up types that activate on winning spins. The Cross power-up removes blockers in a plus pattern, the Horizontal removes entire rows, the Vertical removes entire columns, and the 3×3 removes a square block. The game starts each spin with 2 power-ups active, meaning grid expansion happens with reasonable frequency. Each power-up destroyed moves you closer to the full 6×10 configuration, providing a tangible sense of progression that sustains engagement through the base game. Alongside these mechanics sit tile blockers and respins, creating a layered system where something is almost always happening on the reels.
Community feedback highlights that whilst the base game delivers consistent action through these power-up mechanics and cascading wins, it also includes plenty of dead spins and smaller top-up wins between more significant payouts. This aligns perfectly with the game’s high volatility profile—the trade-off for explosive potential is patience through slower periods. For high-volatility enthusiasts, this pacing feels natural. For casual players accustomed to more frequent base-game wins, the experience can feel repetitive despite the mechanical depth.
Bonus Features & Free Spins
Free spins in Space Miners trigger when 3 or more Bonus symbols land in any position on the reels. You’ll receive a minimum of 6 free spins, with an additional 2 spins awarded for each bonus symbol beyond the initial 3. During the feature, each additional bonus landing grants +1 extra spin, creating retrigger potential that can extend the round substantially. Crucially, the free spins mode grants 4 power-ups per spin instead of the base game’s 2, dramatically increasing grid expansion speed and win ways accumulation.
The free spins feature represents the slot’s high-volatility showcase. Reaching the full 6×10 grid with 1 million ways to win during bonus is genuinely rewarding and feels like an achievement. Community commentary notes, however, that once the maximum grid is achieved, the feature can dead spin to the end—the mechanics are hit or miss rather than consistently explosive. Winning combos that unlock the full grid are exciting, but the feature doesn’t guarantee massive payouts even at full expansion. This realistic volatility keeps expectations grounded; the 50,000x maximum win is theoretically possible but rare. In practice, players report typical bonus feature wins reach around the 3,000x range even with bonus buy purchases, making the theoretical maximum more aspirational than achievable.
Bonus Buy Feature
Space Miners includes a Bonus Buy option at 100x the current bet, granting immediate access to the free spins feature. This option boosts the game’s RTP to 97.14%—up from the base 96.47%—making it attractive to bonus-focused players seeking higher long-term returns. Important note: Bonus Buy is not available in UK jurisdictions due to UKGC regulatory restrictions, limiting this option for British players.
Our Honest Verdict
Space Miners delivers exactly what high-volatility enthusiasts are seeking—a mechanically engaging game built on progression and grid expansion rather than chasing marquee features or tired Megaways trends. Relax Gaming’s decision to chart an independent course paid dividends here. The graphics are genuinely appealing with superb visuals and great sound design, creating an immersive space-mining atmosphere that, whilst sharing obvious inspiration from Reactoonz, feels like a thoughtful homage rather than a copycat effort.
Where Space Miners shines is in its mechanical depth and progression system. The power-up blocker mechanics create meaningful gameplay tension as you expand the grid, and the scaling ways-to-win system (729 to 1,000,000) feels earned rather than arbitrary. For players who enjoy watching their mechanical manipulations unfold, this game delivers.
That said, the game has clear limitations that deserve acknowledgement. The base game can feel drawn out, filled with spins that don’t deliver meaningful progress. The free spins feature, whilst visually rewarding at full grid expansion, remains hit-or-miss—landing big wins isn’t guaranteed even when all mechanics align. Most importantly, the gap between the advertised 50,000x maximum win and typical real-world outcomes (3,000x range) represents a substantial realism gap that might frustrate expectations-management in younger or less experienced high-volatility chaser communities.
Space Miners positions itself as a premium title within Relax Gaming’s catalogue and delivers on that promise through mechanical innovation and visual polish. It’s not a game for players seeking constant base-game wins or casual entertainment—this is built for high-volatility enthusiasts willing to engage with system complexity and accept extended dry spells for explosive potential. Within that audience, Space Miners deserves strong consideration as a well-crafted, genuinely innovative release that expanded the conversation beyond mechanical trends dominating 2021-2022.
Final Rating: 8.2/10
A standout high-volatility release with innovative mechanics, excellent presentation, and meaningful mechanical depth. Recommended for grid-expansion enthusiasts and high-volatility chasers. Not suitable for casual players or those seeking consistent base-game action.
