How to play
Connect each pair of matching markers with a route. Drag from one marker to its partner, moving up, down, left, or right one cell at a time.
Routes can't cross or overlap, and you win only when every pair is connected and every cell on the map is covered.
Drag back along a route to shorten it, or start again from a marker to redraw it. Dragging across another color's route cuts it short.
