Space Miners (Relax Gaming) Slot Review

Space Miners: Slot Overview

Space Miners is a space-themed video slot developed by Relax Gaming and released on February 8, 2022. The game transports players to an outer space environment populated by cube-shaped creatures and miners extracting valuable minerals. It employs a dynamic gameplay style centered on a 6-reel grid that starts with 3 rows and can expand up to 10 rows, unlocking from 729 ways to win to a maximum of 1,000,000 ways to win through cascading tumbles. Wins trigger the unlocking of adjacent blocked positions, allowing new symbols to drop in, reminiscent of cluster-tumble mechanics in titles like Cluster Tumble. This high-volatility slot appeals to players seeking expansive grid growth, high potential payouts, and feature-rich sessions with bonus buys, targeting enthusiasts of innovative, ways-to-win progressives who enjoy prolonged building phases leading to massive combinations.

Design and Graphics

The visual aesthetic of Space Miners immerses players in a vibrant cosmic setting. The backdrop features a starry expanse with floating cube-shaped meteorites and animated space miners drifting by, creating a lively interstellar atmosphere. An introductory cinematic sequence depicts a space miner harvesting minerals, setting a treasure-hunting tone. The 6×3 to 6×10 reel grid is framed against this dynamic space vista, with crisp, colorful animations accompanying tumbles and expansions. Symbols are thematically cohesive: low-paying minerals in blue, purple, green, and yellow evoke glowing gems, while high-paying space miners in blue, green, orange, and red depict cartoonish characters with expressive details. The wild symbol appears as a mineral-laden cart, and the scatter resembles a spaceship. Four Power Up symbols—marked by cross, horizontal arrows, vertical arrows, and a 3×3 circle—add interactive flair with explosive destruction effects when activated.

Animations are smooth and engaging, with expanding wilds, blocker destructions, and cascading symbols featuring particle effects and glows that enhance win celebrations. The overall polish is high, with vibrant color palettes blending neon hues against deep space blacks for visual appeal. The interface supports seamless play across desktops, mobiles, and tablets, maintaining sharp resolution and responsive touch controls on smaller screens. Audio complements the theme with futuristic electronic soundscapes, subtle mining clinks, and escalating intensity during grid expansions, contributing to an polished, luxurious presentation without overwhelming the core mechanics.

Gameplay Mechanics

Space Miners operates on a 6-reel setup with variable 3 to 10 rows, offering up to 1,000,000 ways to win. Winning combinations form when 3 or more identical symbols land on adjacent reels starting from the leftmost reel. Upon a win, winning symbols and adjacent locked blockers are removed, unlocking new positions on the grid. Fresh symbols then tumble down to fill all unlocked spots, potentially chaining multiple reactions per spin. This tumble mechanic drives the core flow: each cascade expands the grid by revealing previously blocked positions, increasing active ways until no new wins occur, at which point the progress resets for the next spin.

Special symbols enhance base game dynamics. The wild symbol (mineral cart) substitutes for all pay symbols except scatters and expands to cover every open position on its reel upon landing, boosting combination potential. Scatter symbols (spaceship) are collected during the spin sequence; 3 or more trigger Free Spins. Four Power Up symbols hide behind blockers: Cross (destroys horizontal/vertical blockers from its position), Horizontal (clears row-wise), Vertical (clears column-wise), and 3×3 (clears a 3×3 area). Multiple Power Ups can activate and overlap in a single cascade, accelerating grid unlocks. The base game hit frequency stands at 20.18%, with sessions building tension as the grid grows but resetting frequently to emphasize volatility.

Bonus Features

The slot’s features revolve around grid expansion and sustained unlocks, with Power Ups available in the base game and Free Spins providing persistence. Power Up Features activate when a blocker containing one is destroyed during tumbles. These can chain reactively:

Overlaps amplify destruction, rapidly clearing large grid sections. Free Spins trigger by collecting 3+ scatters in base game tumbles (6 spins base +2 per extra scatter). Landing additional scatters in Free Spins grants +1 spin each. Crucially, all unlocked positions from prior tumbles persist across the entire bonus round, enabling progressive builds toward full-grid potential without resets. Wild expansions and Power Ups remain active, heightening volatility.

The Bonus Buy option costs 100x the bet to instantly access Free Spins, elevating RTP to 97.14%. These mechanics synergize for escalating excitement, with base game previews of potential giving way to bonus persistence for peak payouts.

Betting Options and Payouts

Betting ranges from a minimum of €0.10 to a maximum of €20 per spin, accommodating casual and mid-stakes players. The game’s RTP is 96.47% in standard play, rising to 97.14% via Bonus Buy. Classified as high volatility, it delivers infrequent but substantial wins, evidenced by a 20.18% hit frequency. The standout attraction is the 50,000x stake maximum win, achievable through full-grid unlocks and chained high-symbol cascades in Free Spins.

Payouts scale with grid size and symbol clusters, favoring high miners (up to 5x for 6) over lows (0.4x). Tumbles and Power Ups compound multipliers implicitly via expanded ways, though no explicit global multiplier exists. Max win probability is not specified, but high volatility implies rare hits at the ceiling. Payout behavior rewards patience: base game builds tease potential before resets, while Free Spins sustain progress for outlier sessions.

Conclusion

Space Miners excels in its innovative tumble-expansion mechanics, delivering thrilling grid growth up to 1,000,000 ways and a compelling 50,000x max win potential, bolstered by persistent Free Spins and synergistic Power Ups. Strengths include above-average RTP, mobile optimization, and visually striking space theme with smooth animations. The Bonus Buy enhances accessibility for high-volatility pursuits. Weaknesses lie in base game resets that can frustrate momentum, potentially prolonging dry spells despite the 20.18% hit frequency, and reliance on Free Spins for peak performance. Players can test the slot risk-free using the built-in demo available on this page. Overall, it offers a balanced, high-reward experience for fans of progressive grids, though patience is key in its high-volatility framework.
