Idle Space Mining is an incremental clicker about digging your way across 12 galaxies. Drag your miners onto rocks and watch them dig. Merge two of a kind into a stronger miner. Dig out machines buried in the ground, build them, and they keep mining while you are away. Mine through the walls, reach the launch pad, and launch to the next planet. DIG WITH YOUR CREW Every rock holds gold ore, and now and then you find a rare Dark Matter rock. Pick which rocks your crew works and collect what they drop. Your crew comes with you to every new planet. MERGE YOUR MINERS Two miners of a level make one of the next. Higher levels dig faster. MINE THROUGH THE WALLS Each area ends in a wall. Dig a way to it, put your crew on it, and mine it down to open the next area. DIG OUT YOUR MACHINES Every planet starts with just the Ore Crusher. Fifteen more buildings lie buried across the galaxies, from the Power Plant and Drill Press to the Refinery, Smelter and Nuclear Plant. Reach one and buy more of it from the Upgrades menu. 96 PLANETS, 12 GALAXIES Eight planets in each galaxy, each with its own look, its own rock and its own walls. Launching earns Dark Matter, which you keep forever. FIVE DARK MATTER UPGRADES Spend Dark Matter on Ore Yield, Dig Speed, Miner Slots, Dark Affinity and Auto-Collect, ten levels each. They make every planet after it faster. RESEARCH AND COLONY BOOSTS Dig out the Power Core to open research, and grow the whole colony with Colony boosts. EVENT PLANETS Event planets open for three days at a time. Everyone starts with the same kit. Mine as many rocks as you can and see your rank on the Game Center leaderboard: your Top %, and where you stand among friends. Nothing is for sale on an event planet. THE LAST PLANET Mine through planet 96 and you have crossed all 12 galaxies. A finish screen marks it, and the event planets keep going after that. COMETS, DAILY GOALS, ACHIEVEMENTS Catch comets for a burst of ore. Clear daily goals. Claim achievements for a permanent bonus. EARNS WHILE YOU SLEEP Your machines keep mining when the app is closed. Come back to a pile. One optional ad, only if you want it: watch it for double production for four hours. No banners, no interstitials, nothing that interrupts play. No energy timers. Cloud save keeps your progress safe.
