How to play 7×7 Link Puzzle

Join each pair of dots of the same colour with a line. Lines go up, down, left and right, never cross, and must fill every cell of the board. Press a dot and drag to its partner; drag back to shorten a line. Each board has exactly one solution.

Smaller boards are quicker; larger boards have more pairs and longer lines. Your board is saved in this browser, so you can come back to it.
