Link Line

Link Line is a calm logic puzzle about connecting pairs of colored dots. Every board is a square grid – from 5x5 up to 10x10 – and each color appears exactly twice.

A level only counts as solved when every pair is joined, no two lines cross and every single square on the grid is covered. Bigger boards bring more colors, and there are thousands of levels to work through, so it is a great choice when you want a puzzle that rewards careful planning.

Tap a colored dot and drag to draw a line to the dot of the same color.

Lines cannot cross: drawing over an existing line breaks it.

Fill every empty square of the grid with lines to finish the level.
