Sehrohr auf!

The playing field is put into a plastic frame and placed on edge. Each player equips the field on his side with ships, which are inserted into the holes in the playing field. An opaque plastic sheet between the layers of the playing field makes it impossible to see the opposing ship positions. At the bottom of the playing field a "periscope" is hooked, with which one can spy out the opponent's side of the playing field under limited conditions. The goal is to remove the enemy ships from their position with the help of torpedoes and depth charges. These are inserted into a hole on your own side and push out the enemy ship on the opposite side. The winner is the player who is the last to have his own ships left in the playing field. —user summary
