Join each pair of coloured dots with a string, dragging your finger square by square. Strings never cross and, in the end, no square can be left empty.
Solved by thinking. Every board has a single solution, checked before it reaches you: you never need to guess. If you get stuck, the hint tells you which square can be worked out and why, or which part you have got wrong.
Three modes. Classic with four levels (from 5×5 to 11×11), a Daily challenge with the same board for everyone, and Zen with no timer. Undoing and redrawing a string costs nothing.
For everyone. Each colour has its own symbol on the dots, so you can tell them apart without relying on colour. Dark, light and high-contrast themes, and keyboard play.
Genuinely calm. No ads, no purchases and no accounts. Your games, stats and achievements stay on your device. In English, Spanish and Catalan.
Drag your finger from a dot to the other dot of its colour: you leave a string behind, square by square and never diagonally. Strings cannot cross; if you go over another one, you cut it. You win when every pair is joined and no square is left empty.
