I propose to recall what we ourselves entertained in the classroom at school. It is clear that many of you now say: "In the lessons we learned ...". I do not believe :)
1. The most common and favorite tetrad game of all time has been and remains "Battleship»:
2. Another kind, a nursery, an intellectual game "Hangman»:
One player thinks of a word - writing on paper first and last letter of the word and mark the places for the rest of the letters. Draw a gallows with a noose.
