Net <p> Rotate the grid squares so that they all join up into a single connected network with no loops. <p> Left-click in a square to rotate it anticlockwise. Right-click to rotate it clockwise. Middle-click, or shift-left-click if you have no middle mouse button, to lock a square once you think it is correct (so you don't accidentally rotate it again); do the same again to unlock it if you change your mind. <p> Squares connected to the middle square are lit up. Aim to light up every square in the grid (not just the endpoint blobs). <p> When this gets too easy, select a 'wrapping' variant from the Type menu to enable grid lines to run off one edge of the playing area and come back on the opposite edge!
