StarLine: One Line Puzzle

One single line. One whole world.

StarLine is a one-line drawing puzzle. Connect every line without lifting your finger, and without tracing the same line twice. The rule fits in a sentence. Putting it down is the hard part.

■ 1,000 stages, every one verified
Forest Tales, A Day in the City, Ocean Voyage, Journey Through Space. Every stage was generated and then actually solved by a solver before it shipped, so there are no impossible puzzles and no filler. Difficulty runs from Beginner to Extreme, and each world climbs the same curve.

■ 25 hidden constellations, taken from the real sky
Orion, Cassiopeia, Ursa Major and more. The stars sit where they sit in the sky — real right ascension and declination, projected onto the board. Complete one and its story opens up: when to look for it, what makes it worth finding, and the names of its brightest stars. They unlock as you clear stages. Nothing to buy.

■ Today's one-line puzzle
One puzzle a day, the same one for everyone, everywhere. Clear it and share your time and star rating exactly as it happened. Your streak keeps count.

■ 24 pictures to finish
Every stage resolves into a picture — a fox, a lighthouse, a rocket. Collect them in the gallery.

■ Plays anywhere
No sign-up, no account, no server. The whole game runs offline, and your progress stays on your phone.
