Sinking ships

Instructions

Place ships:
Each player places their ships face down on the blue playing field.
You have the following ships to choose from:
1 battleship (4 fields)
2 cruiser (3 fields each)
2 destroyers (2 fields each)
The ships must not touch each other, run diagonally or go over corners.
Gameplay:
Take turns and name a position, e.g. "B3".
The opponent says whether a ship has been hit or missed.
Mark the hits with an X and misses with an O on the red playing field.
Winner:
The game ends when all of a player's ships have been sunk.
