Tap an asteroid. Build a mining empire. Then destroy it — and come back stronger. IDLE SPACE MINING is an idle game about scale. You start hand-mining ore from a bare rock. You end up rewriting local physics so the ore was always there. BUILD THE COLONY Twenty-six machines, from a rickety Drone Hangar to the Terminus Drillhead. Each one runs its own harvest cycle — watch the bars fill, watch the ore land. Every 10 you own doubles that machine's output, and every tier lifts the one beneath it. CHOOSE YOUR DOCTRINE At each tier you pick ONE of three paths and forfeit the other two. Triple your early generators, or cut the price of everything, or tighten your milestones. There is no right answer — and you re-decide every single run. ASCEND When growth stalls, collapse the whole colony into a singularity. You lose your ore, your generators, your tech. You keep DARK MATTER — and every scrap you have ever earned makes you permanently stronger. Dark Matter is deliberately scarce. Each one matters. HEAT DEATH Then there's the prestige above prestige. Let the universe run down, trade everything — even your Dark Matter — for Star Shards, and buy upgrades that survive the end of everything. TAKE ON CHALLENGES Mine with no hands. Run with triple-length cycles. Build with only three generator types. Beat one and keep the bonus forever. CATCH COMETS Comets drift past while you play. Tap one for a lump of ore or a burst of production. EARN WHILE YOU SLEEP Your colony keeps mining when the app is closed. Come back to a pile. One optional ad, and only if you want it: watch a Supply Drop for double production for four hours. No banners, no interstitials, nothing that interrupts play. No energy timers, no countdown "offers". Just numbers going up, forever.
