Game rules:
I believe that everyone knows how to play the old game, but if you have spent your life in a cave or another planet, here are the rules of the game:
The board is composed of three rows and three columns.
Two players choose the markings they wish to play with (usually a 'circle' and 'xis') and alternately fill in the empty gaps on the board.
The goal is to put three circles or xs in line, be it vertical, horizontal or diagonal, while trying to prevent your opponent from doing the same.
If one of the players can put three elements in line, the winner is declared. But if no such achievement is achieved, the tie is declared ... when this happens, in Brazil, it is often said that the game "got old".
