Tic-Tac-Toe, often referred to as Noughts and Crosses, is a classic two-player game played on a 3x3 grid. The game's objective is simple: players take turns marking empty cells with their designated symbol, traditionally "X" for one player and "O" for the other. The goal is to form a horizontal, vertical, or diagonal line of three of your own symbols before your opponent does.

Due to its straightforward rules and limited grid size, Tic-Tac-Toe serves as an introductory game for children and a quick amusement for all ages. However, with optimal play, the game will always end in a draw, making it a solved game from a strategic perspective. Despite its simplicity, Tic-Tac-Toe continues to be enjoyed as a casual pastime and a starting point for learning basic game strategy.
