TIC TAC TOE

This is a simple smart contract to play Tic Tac Toe on the blockchain.

How to Play

1. Create a Game: Call the createGame function with the address of the person you want to play with as a parameter. This will create a new game.

2. Accept Invitation: The invited player should accept the invitation by calling the acceptInvitation function with the gameId of the game that was created.

3. Start Playing: Once the invitation is accepted, the game begins. Check who the first player is and start making moves.

4. Make a Move: To make a move, call the makeMove function with the gameId and the square position where you want to place your mark.

5. Game Completion: The game ends when one player wins or when there's a draw. At this point:

   • The game status changes to Completed.
   • If there's a winner, their address will be saved in the winner field.
   • In case of a draw, the game status will change to Completed, but the winner field will be set to the zero address.
