Build planets by tapping cosmic materials into orbit at the correct velocity and mass. Too fast and the material flies off into space; too slow and it crashes into the planet surface. Rare rare-earth elements drift through the system once per build cycle and score triple when incorporated into the planetary structure.

Rush across the Arctic ice tapping polar creatures before they escape under the ice floe. Penguins waddle slowly and score one point, Arctic foxes dart quickly and score three, and a rare polar bear surfaces briefly worth twenty points. Ice cracks appear between taps — step on one and fall through, ending the polar rush.

Void creatures phase in and out of a dimensional grid and you tap each the moment it materialises before it vanishes back into the void. Gold void creatures score triple but phase out in half a second. Bomb creatures wear convincing disguises — a faint purple halo is the only tell before the tap that ends your run.
