Pipes

Drag from a dot to draw a pipe to the other dot of the same color.

Pipes can’t cross or overlap, except on bridges.

To win, connect every pair and fill every square.

Bridge (striped square): one pipe goes across and another goes up-down. Pipes go straight through, and both lanes must be used.

Portal (numbered ring): a pipe that enters one comes out of its twin with the same number. Keep drawing from there.

Drag back along a pipe to shorten it, or press any point on a pipe to redraw from there.

Solved!
