Expedition: Clicker to the Edge of the Universe

Pluto. A crust of nitrogen ice, minus two hundred and thirty degrees, four billion kilometers from the Sun. You have one drill. You have one drill. Every tap bites into the crust. What you earn buys better drills, rovers, domes, a relay on Charon — and everything you buy appears on the planet itself. Fill the bar, crack the core, move on. Neptune's storms. Uranus, tipped on its side. Saturn's rings, Jupiter's moons, a colony spreading across Mars, city lights waking on Earth's night side. At the Sun there is no planet left — ring by ring, a Dyson sphere closes around the star. Then the route leaves the solar system: Sagittarius A* at the heart of the Milky Way, and quasar TON 618, heavier than every star in our galaxy combined. Twelve worlds, each with its own resource and its own discoveries. Every core you crack makes the expedition permanently stronger. Reach the end and you can collapse into a singularity and run it all again, twice as fast.
