Rules: The grid shows the ocean with a hidden fleet of ships which you see on the right hand side and the bottom of the grid. The ships may be placed horizontally or vertically so that no ship touches another, not even diagonally. The numbers on the top and on the left hand side of the grid show how many cells in the corresponding row and column are occupied by ship segments. The target is to discover where all ships are located.
Tipp: Cross out all cells which cannot occupy a ship segment.
