Project Overview

This project is a Tic Tac Toe game implemented in Python using the Tkinter GUI library. Users can enter the desired board size (e.g., 3 for 3×3, 4 for 4×4) to start the game. Players take turns clicking on empty cells to place their mark (X or O), and the game checks for a winner after each move. If a player wins or the board is full (tie), a message is shown and the board resets automatically.
