Objective / Rules - Find the route of the track. - There is only one start and one end to the track. - The track doesn't cross itself. - The numbers across the top and down the side tell you how many track pieces are in the respective row or column. - Clicking a square places an unknown track piece (helps). - Clicking between the squares forces a track direction (required).
Mouse Usage Note: only when supported by your computer/device/browser/etc. Left-click = Blank >> Track >> No Track >> Blank. Right-click = Blank >> No Track >> Track >> Blank.
Clicking a square allows you to flag the square as an unknown track piece, or a cross for squares that you know are not track pieces. Clicking between the squares forces a track direction.
Checking If you click 'Check' the system will check for incorrect track pieces (but doesn't check between the squares). If 'Show mistakes when checking' is checked they will be marked with a little red X.
Uniqueness Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules.
