Link shaded cells to solve each puzzle.
A link is valid if it has the length and number of intersections indicated in the corners of certain shaded cells. The required lengths are shown in the upper-left corners. The required number of intersections are shown in the lower right corners. A puzzle is solved when you create valid links between each shaded, numbered cell.
Controls are strictly click & drag. Your progress is automatically saved.
There is also a tutorial outlining how to go about solving the puzzle at http://blog.eketech.com/?
