An early variant of Tic tac toe was played in the Roman Empire, around the first century BC. It was called Terni Lapilli and instead of having any number of pieces, each player only had three, thus they had to move them around to empty spaces to keep playing. The game's grid markings have been found chalked all over Rome. Tic tac toe (or Noughts and crosses, Xs and Os) 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 respective marks in a horizontal, vertical, or diagonal row wins the game. Strategies: -Win: If the player has two in a row, they can place a third to get three in a row. -Block: If the opponent has two in a row, the player must play the third themself to block the opponent. -Fork: Create an opportunity where the player has two threats to win (two non-blocked lines of 2). -Blocking an opponent's fork: Option 1: The player should create two in a row to force the opponent into defending, as long as it doesn't result in them creating a fork. For example, if "X" has a corner, "O" has the center, and "X" has the opposite corner as well, "O" must not play a corner in order to win. (Playing a corner in this scenario creates a fork for "X" to win.) Option 2: If there is a configuration where the opponent can fork, the player should block that fork. Center: A player marks the center. (If it is the first move of the game, playing on a corner gives "O" more opportunities to make a mistake and may therefore be the better choice; however, it makes no difference between perfect players.) -Opposite corner: If the opponent is in the corner, the player plays the opposite corner. -Empty corner: The player plays in a corner square. -Empty side: The player plays in a middle square on any of the 4 sides.
