Tap the core!
Planet Builder Idle drops you into the cold edge of empty space and dares you to build the most ambitious matter empire on the web. It all starts with a single tap on the core: each press mints a little Matter, and Clump…
1. Tap or click the core (or press Space) to earn your first Matter.
2. Open the Buildings tab and buy Little Engineers to start earning Matter automatically.
3. Reinvest into stronger helpers like Turbo Engineers and Cosmic Engineers as costs climb.
✦ Most ambitious matter theme set in the cold edge of empty space
✦ Five upgradeable helpers from Little Engineers to Cosmic Engineers, each with its own boosts
✦ Idle income that keeps earning while the tab is closed, with capped offline catch-up
