Mastering Tic Tac Toe with Python


Tic Tac Toe Python

Playing computer games is a great way to unwind or challenge yourself. Some people even do it professionally. It’s also fun and educational to build your own computer games. In this tutorial, you’ll build a classic tic-tac-toe game using Python and Tkinter.

With this project, you’ll go through the thought processes required for creating your own game. You’ll also learn how to integrate your diverse programming skills and knowledge to develop a functional and fun computer game.

Project Overview

In this tutorial, you will learn how to program the classic tic-tac-toe game’s logic using Python and create the game’s graphical user interface (GUI) using the Tkinter toolkit. By integrating the game’s logic and GUI, you will develop a fully functional tic-tac-toe game.


Before diving into the project, it’s essential to have a basic understanding of Python programming and object-oriented programming (OOP) concepts. Additionally, having some familiarity with the Tkinter library and the model-view-controller (MVC) pattern will be helpful.

Step 1: Set Up the Tic-Tac-Toe Game Board With Tkinter

The first step is to create the game board using Tkinter. Ensure that you have the right version of Tkinter installed and then create a class to represent the game board. The game board will visually display the state of the game and allow players to make moves.

Step 2: Set Up the Tic-Tac-Toe Game Logic in Python

After setting up the game board, you need to program the game’s logic in Python. This involves defining classes for the players and their moves, creating a class to represent the game logic, setting up the abstract game board, and figuring out the winning combinations.

Step 3: Process the Players’ Moves on the Game’s Logic

Once the game logic is set up, you need to process the players’ moves to determine if a player has won or if the game has ended in a tie. This step involves validating players’ moves, processing the moves to find a winner, checking for tied games, and toggling players between turns.

Step 4: Process Players’ Moves on the Game Board

To reflect the game state on the graphical interface, you need to handle a player’s move event, update the game board to display the moves, and run the tic-tac-toe game for the first time.

Step 5: Provide Options to Play Again and Exit the Game

In the final step, you’ll build the game’s main menu and implement options for playing again or exiting the game. This step will ensure that players have a smooth experience navigating the game and can choose to continue playing or end their session.


By following this tutorial, you have learned how to build a tic-tac-toe game using Python and Tkinter. You have gained insights into programming game logic, creating a graphical user interface, and integrating both aspects to develop a functional game.

Next Steps

Now that you have built a tic-tac-toe game, you can further enhance it by adding additional features, such as a scoring system, different difficulty levels, or a multiplayer mode. Additionally, you can explore other Python libraries, like Pygame, to create more advanced games.

Remember, building your own computer games is a great opportunity to apply your programming skills and creativity. Have fun and keep practicing!
