Lighthouses is a logic puzzle played on a square or rectangular grid. It contains lighthouses with digits. The digit represents the number of ships lit by the lighthouse.

A ship is lit if it is in the same row or column as the lighthouse, also if a ship is behind another ships or lighthouse. Each ship is lit by at least one lighthouse. The ships are placed so that no ship touches any other ship or lighthouse, not even diagonally.

If you have found the ships of a particular lighthouse, you can click on that lighthouse. Its background then turns green.
