Starline: One Line Puzzle

Starline is a quiet logic puzzle about drawing a single unbroken line.

Every board is a grid of stars. Draw one continuous path that passes through
every square and touches the numbered stars in order — 1, 2, 3, and on to the
last. One line, never lifted. Every puzzle has exactly one solution, and every
solution can be reasoned out. Nothing is guesswork.

FOUR WAYS TO PLAY

★ The journey
Hand-tuned levels gathered into named chapters, from First Steps to First
Light. The boards grow with you, and a star map lights up as you restore each chapter.

★ Daily Sky — one puzzle a day
The same board for every player, every day. Solve it and keep your streak.

★ Zen — no scoring, no pressure
Endless puzzles with no par, no timer and no stars. Solve one, draw another.
No interstitial ads here, ever — by design.

★ Night Watch — the endless run
Opens once the first sky is whole. Pick your sky, then solve as far as your
streak carries you.
