Pipe Flow

Pairs of coloured dots sit on a square grid. Draw a pipe from each dot to its twin through squares that touch. The board is done when every pair is joined and every square is covered.

That last condition is what makes it a puzzle rather than a maze, and it is also why every board has a solution. The generator walks ONE path over every square first, then cuts that path into a segment per colour - so the finished picture existed before the puzzle did, and the puzzle is just that picture with its middles rubbed out.

Nothing is timed and nothing is lost. A wrong pipe is undone by drawing over it.
