In this article, we’ll be focusing on how to use TensorFlow to create a simple tic tac toe AI. The game of tic tac toe has been around for centuries and is a popular game for both children and adults. The game can be played with two players, each taking turns placing their mark (X or O) on a 3×3 grid. The goal of the game is to be the first player to get three of their marks in a row, either horizontally, vertically, or diagonally. If all nine spaces on the grid are filled and no player has three in a row, the game is considered a draw.

What is TensorFlow?

TensorFlow is a powerful tool for machine learning. It allows you to build and train neural networks to recognize patterns, make predictions, and ultimately solve problems.

TensorFlow can be used for a variety of tasks, including image classification, natural language processing, and even video games. In this blog post, we will focus on how to use TensorFlow to train an AI to play the game of Tic Tac Toe.

What is a Tic Tac Toe AI?

A Tic Tac Toe AI is a computer player that can beat a human player at the game of Tic Tac Toe.

To create a Tic Tac Toe AI, we need to use a technique called reinforcement learning. Reinforcement learning is a type of machine learning that allows an AI to learn by trial and error. We will create a simple Reinforcement Learning algorithm that will teach our AI to play Tic Tac Toe.

First, we need to define our environment. The environment is the game board and the rules of the game. We will use the popular 3×3 Tic Tac Toe board for our environment. The environment will have two players, X and O. The goal of the game is to get three X’s or three O’s in a row, column, or diagonal on the board. If neither player gets three in a row, then the game is a draw.

Next, we need to define our agent. The agent is the Tic Tac Toe AI that we will be training. We will represent our agent as a simple neural network with nine input nodes (one for each position on the 3×3 board), eighteen hidden nodes, and one output node. The output node will return either 0 (for choosing an empty position on the board), 1 (for choosing an X position on the board), or 2 (for choosing an O position on the board).

Now that we have defined our environment and our agent, we can start training our AI! We will train our AI using a reinforcement learning algorithm called Q-learning. Q-learning is a model-free reinforcement learning algorithm that allows agents to learn by trial and error.

To train our AI, we will first initialize the Q-table to all zeros. Then, we will play a few hundred games of Tic Tac Toe against ourselves. For each game, both players will make their moves according to the Q-table values (i.e., they will choose the move that maximizes their Q-value for that state). After each game, we will update the Q-values in the Q-table according to whether X won, O won, or it was a draw. Finally, after training is complete, our AI should be able to beat a human player at Tic Tac Toe!

How to Train Your AI

If you’re new to TensorFlow, the official tutorial can help you get started. You can also find a number of code samples in our GitHub repository. In this post, we’ll show you how to train your TensorFlow AI to play the classic game of tic tac toe.

To get started, you’ll need a few things:

– A computer with TensorFlow installed
– A copy of the tic tac toe game board
– Two players who are willing to take turns playing the game (one will be the “teacher” and the other will be the “student”)
– A way to keep track of the game’s history (we’ll use a TensorBoard for this)

The first step is to set up your game board. You can do this by creating a new file and adding the following code:

import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt

def tic_tac_toe():

# Define game parameters here

# Define board here

# Define player1 here

# Define player2 here

# Play the game!

if __name__ == ‘__main__’:

In this code, we’ve imported the required libraries and defined a function called `tic_tac_toe`. This is where we’ll write all of our code for setting up and playing the game. We haven’t added anything to this function yet, but we will in the next step.

Tips for Training Your AI

If you’re just getting started with TensorFlow, the hardest part can be knowing how to actually get started. In this post, we’ll walk through the basics of training your own AI to play a simple game of tic-tac-toe.

In reinforcement learning, an AI trains by playing games against itself or other opponents. The goal is to learn a set of rules, or a policy, that will let it make the best decisions possible in any given situation. Every move the AI makes is based on its current policy, and as it continues to play games and explore new situations, it can refine its policy to become even better.

When training your AI, there are a few things to keep in mind:

1. Define a clear goal for your AI. What do you want it to be able to do? In the case of tic-tac-toe, the goal is simple: win the game.

2. Start with a very simple policy. As your AI plays more games and explores more situations, it can gradually refine its policy and become more sophisticated.

3. Make sure your AI has enough opportunities to explore different situations. If it only ever plays one type of opponent, or if it always starts the game in the same way, it may never learn how to deal with new situations.

4. Be patient! It takes time for an AI to learn anything useful – don’t expect miracles overnight.

Testing Your AI

The best way to see if your AI is learning is to pit it against other AIs or humans in a tournament. If it’s consistently losing, then you know that it still has some learning to do. If it’s winning some and losing some, then you know that it’s on the right track but still needs some work. And if it’s winning most of the time, then congratulations-you’ve got a champion on your hands!

To test your AI’s mettle, you can use any standard tic tac toe board. Alternatively, you can also use an online tic tac toe board like this one from TensorFlow Playground.

Once you’ve found a board, have your AI play against other AIs or humans as many times as possible. Keep track of how often it wins, loses, and ties; and try to beat its previous score. The more games your AI plays, the better it will become at learning from its mistakes and improving its strategy.

Improving Your AI

If you’re anything like me, you’re not satisfied with your Tensorflow Tic Tac Toe AI just winning all the time. You want it to be the best it can be! Here are some ways you can improve your AI’s performance:

1. Increase the number of training iterations. The more times your AI plays against itself, the better it will get at playing Tic Tac Toe.

2. Try different learning rates. A high learning rate will make your AI learn faster, but it might also make it more likely to forget what it has learned so far. A low learning rate will make your AI learn slower, but it will also make it less likely to forget what it has learned.

3. Try different neural network architectures. Different neural network architectures can have different strengths and weaknesses. For example, some neural networks are better at learning from data with a lot of noise, while others are better at learning from data with a limited amount of data.

4. Try differentoptimizers.Different optimizers can have different strengths and weaknesses. For example, some optimizers are better at finding global minima, while others are better at finding local minima.

5. Try different weight initializations. Different weight initializations can have different effects on training time and final accuracy. For example, some weight initializations result in faster training times, while others result in higher final accuracy levels


We have now completed our tutorial on training a Tensorflow model to play the game of tic tac toe. We started by building a basic model, and then added more layers and nodes to increase its accuracy. Finally, we trained it on a larger dataset to improve its performance even further.
