Morskoy Boy

Morskoy Boy (Sea Battle) is an old board game that was once played at home on paper. The idea is that each player has a square (in a grid notebook). Each square contains 10 ships (stripes of one square and varying lengths): 1 ship in 4 squares, 2 in 3, 3 in 2, 4 in 1. The 10 ships occupy a total of 20 squares. Then, each player (not randomly, depending on where and how their opponents have placed their ships) chooses a square in their opponent's square to shoot at. If a ship appears there, it's your turn again; if not, it's your opponent's turn. You can play with a friend or against the computer; if against the computer, there are three difficulty levels to choose from.
