⛏️ Helium-3 Lunar Shaft

<p><strong>Helium-3 Lunar Shaft</strong> is a free mining empire idle game built around a shaft on the dusty moon. You start small with a single tap, but the magic is automation: low gravity speeds hauls, and soon your Helium-3 climbs all on its own. Spend it on prospectors, ore trolleys and eventually a planet drill — each one quietly compounding your output while you do other things.</p><p>This game runs on a prestige-hungry pace built around frequent resets for permanent power. The loop is pure, moreish number-go-up: dig for an instant boost, reinvest into your crew, grab milestone rewards, then Cave In for permanent Bedrock Cores that make every future run faster. Helium-3 Lunar Shaft keeps earning offline, so there's always a satisfying welcome-back bonus waiting. It runs instantly in your browser on phone, tablet or desktop with smooth 60fps visuals, WebAudio sound you can mute, haptics and reduced-motion support — no install, no sign-up, just tap and grow.</p>
