What is Mine Line?
Mine Line is an underground simulation and adventure game developed by Shoom Games, released on October 23, 2024. The core gameplay loop revolves around piloting a miner downward into subterranean caverns, linking adjacent rocks together in sequences to trigger large resource combos, and managing fuel to survive deep underground. Unlike standard grid digging titles where blocks are broken one by one, progress here depends on connecting paths across multiple minerals to maximize your harvest in a single move. The game runs directly in any modern desktop or mobile web browser with nothing to install.
Key features
- Chain combos: Connect clusters of matching rocks into continuous lines to harvest entire veins at once rather than digging individual tiles.
- Jetpack mobility: Navigate vertical shafts and deep chasms using thruster flight to reach rich mineral pockets.
- Fuel economy: Convert mined minerals directly into jetpack propellant to extend digging runs into deeper subterranean layers.
- Powerup upgrades: Trade surplus collected resources for shop enhancements that improve digging efficiency and overall survivability.
- Dual control options: Steer the miner with standard directional letter keys or arrow inputs, with dash acceleration available via Shift.
- Cross-platform support: Play smoothly on desktop computers, tablets, or smartphones across horizontal and vertical screen orientations.
How to play
- Begin each run by dropping into the cavern shaft and inspecting nearby mineral formations.
- Navigate across the rock faces using your movement keys while monitoring remaining fuel supplies.
- Trace paths across groups of stones to connect them and initiate resource-clearing combos.
- Feed gathered raw materials into your thruster system to sustain flight deep below the surface.
- Sell accumulated gems and rocks at the surface shop to secure permanent equipment upgrades.
- Return to the underground tunnels equipped with better gear to dig farther and extract rarer treasures.

Resource economy and jetpack fuel
The central mechanic of Mine Line balances immediate survival against long-term progression. Every underground expedition consumes thruster propellant, which can be refilled during the dive by converting mined rocks directly into jetpack fuel. However, stones burned for propulsion cannot be taken back to base. Players must decide continuously how much material to expend on deeper exploration and how much to reserve for selling. Cash earned from liquidated ore funds powerups that boost mining throughput and travel efficiency on subsequent descents.
Tips and strategy
- Prioritize long lines: Connecting large groups of rocks yields substantially higher resource payouts than clearing small pairs, giving you more materials per fuel expenditure.
- Track fuel levels constantly: Burning through propellant without an emergency reserve leaves your miner stranded underground, cutting the run short.
- Use dash sparingly: Holding Shift delivers rapid bursts of speed to evade tight spots, but excessive boosting rapidly drains your thruster reserves.
- Balance fueling against sales: Spend only the bare minimum ore needed to keep moving, reserving high-grade rocks to purchase permanent powerups.
- Scan ahead before descending: Look for dense clusters of valuable stones below your position so you can plan descending paths without backtracking.
