150+ levels across 20+ real constellations, from the Great Bear to the Eagle, every star by its real name.
Its distance, colour, brightness and what its name means. Every star has a true story.
Each chapter ends with a jar drawn for its constellation, like the Eagle’s winged jar.

Icy, labelled and locked jars, joker stars, clock stars, move limits, bound stars, upside-down and one-way jars.

A nebula, Saturn’s ring, the Betelgeuse supernova, the Leonid meteors, the Sombrero Galaxy and Gliese 581.

A daily puzzle, daily quests, streak rewards and a piggy bank.

Every sky object you win stays with you.

Colour-blind mode: every colour has its own shape and mark. Three text sizes. Plays offline; cloud save is optional.
