Dig deep. Strike it rich. Forge an empire among the stars. AstroForge: Idle Miner is a space-mining incremental game where a single tap launches your journey from lone asteroid prospector to galaxy-spanning mining tycoon. Mine ore, refine it into credits, and reinvest in a fleet of ever-more-powerful extractors โ€” 8 tiers of machinery that keep earning while you play and while you're away, thanks to generous offline earnings. TAP, UPGRADE, AUTOMATE Tap to mine by hand, then automate everything. Upgrade your extractors, boost your refinery, and watch your income snowball from pocket change to astronomical fortunes. Active tapping and idle strategy both pay off โ€” play your way. EXPEDITIONS & VOID DIVES When your operation peaks, launch an Expedition: a prestige reset that converts your progress into Star Cores, permanent currency that multiplies all future income. Push even further with Void Dives, a second prestige layer with its own rewards for the truly ambitious. DISCOVER 30 ARTIFACTS Spend Star Cores to uncover from a pool of 30 powerful artifacts. Each discovery grants a unique, permanent boost โ€” duplicates level your artifacts higher. Build the perfect loadout for your mining style. MISSIONS, EVENTS & RIVALS - Daily and weekly missions keep the rewards flowing. - Comet events streak across your operation โ€” catch them for bonus loot. - Rival duels pit your mining output against other pilots in head-to-head challenges. - Climb the live online ladder and out-earn 10,000+ rival pilots. FREE TO PLAY, FAIR TO PLAY AstroForge is free, with optional rewarded ads and in-app purchases โ€” including a one-time Remove Ads upgrade that permanently grants all ad rewards. No paywalls, no forced waits. Earn crystals through missions, events, and achievements, or stock up in the shop. Your empire works the night shift so you don't have to. Fire up the forge, captain โ€” the galaxy's richest veins are waiting.
