Tic-Tac-Toe is a simple turn-based strategy game for two players, X and O. Players take turns marking empty spaces on a 3×3 grid, aiming to create a line of three of their symbols.
A player wins by placing three identical marks in a row, either horizontally, vertically, or diagonally. If all spaces on the board are filled and neither player has formed a winning line, the game ends in a draw.

The game uses the following reward scheme:
| Outcome | Reward |
|---|---|
| Winner | +1 |

| Draw | 0 for both players |
Taking an illegal move immediately ends the game. In this case:
- The player who made the illegal move receives a reward of -1.
- All other players receive a reward of 0.
- Player X starts the game.
- Players alternate turns placing their mark on an empty cell.
- The first player to align three marks in a row, column, or diagonal wins.
- If the board fills up without a winner, the game ends in a draw.
- Making an illegal move immediately ends the game with the corresponding penalty.
