Sliding Puzzle vs One Line

Slide the tiles to connect one unbroken path from start to goal. This is not the usual sliding puzzle where you sort numbers into order. Every tile carries a fragment of a line. Push them into the empty square, rebuild the route in your head, and the whole path lights up the moment it connects. 50 levels, 3x3 to 6x6.
