1. Each player (X and O) can only have a maximum of three pieces on the board at any given time.
2. When a player places their 4th piece, their 1 piece (the oldest one) immediately vanishes from the board.
3. The first player to align three of their symbols in a horizontal, vertical, or diagonal row wins.
4. To prevent the game from going on forever, if the exact same board state occurs three times during a match,
the game is declared as Draw. Your symbol (X/O) is your crown. Try and protect it
