Tips for Playing

  1. Board Coordinates: The board uses a coordinate system where:

    • First number is the row (1-3 from top to bottom)
    • Second number is the column (1-3 from left to right)

  2. CPU Strategy: The AI uses balanced difficulty:

    • Win if possible (50% of the time)
    • Block opponent from winning (30% of the time)
    • Take center (40% of the time)
    • Take corners (30% of the time)
    • Make random moves (more often for easier gameplay)

  3. Multiplayer Tips:

    • Room codes are 6 characters long
    • Share the code with your friend before they try to join
    • Only 2 players per room
    • Rooms are automatically deleted after the game ends

  4. Common Commands:

    • Enter moves: 1 2 (row 1, column 2)
    • Invalid moves show an error - try again
    • Press Enter to continue after game ends
