Tic-tac-toe aka noughts and crosses is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game.
In the past, the game was linked to pagan rituals dedicated to the magic properties of the nine-square grid. The grid was known as the Magic Square because the numbers 1-9 could be arranged so that their sum is the same horizontally, diagonally or vertically. During the Middle Ages, it was believed that this Magic Square held a numerological message about the world.
Today, the game is more known as a simple childhood pastime. The original name of "Tit-Tat-Toe" comes to us from the 16th century. Tit by itself means to slap and a "tit for tat" is retaliation. Toe, which is the third piece placed makes the winning combination by securing the other two pieces.
