Walk the solar system, one tap at a time. Tapstronaut is a free idle clicker game where every tap takes you one step closer to the Sun — start at Pluto, travel real astronomical distances, discover facts about each planet, rebirth for Stardust, and build permanent upgrades that make every journey faster.

Rebirth always sends you back to Pluto. Prestige (finish the Sun) wipes Stardust and shop levels too — except a small permanent boost that never goes away.

You've walked all the way to the Sun. Stardust and shop levels reset — but your permanent tap strength never does.
