One Line: Kolam & Knots

Tap the spaces between dots. Bend the paths. Watch a pattern become one.

One Line is a calm puzzle game inspired by Tamil kolam, Chokwe sona and Celtic knotwork. It uses the mathematics of mirror curves to turn simple choices into intricate patterns. Solve a puzzle and see it bloom in worlds of thread, paper and rain.
