Tic Tac Toe is a two-player game in which the objective is to take turns and mark the correct spaces in a 3×3 (or larger) grid. In this post, we will be creating a Simple Tic Tac Toe game mini project using Python.
Tic Tac Toe Game Mini Project Python
To Build a Simple Tic Tac Toe You need to follow the below steps
Step 1. Download Python
You only need Python to run this script. You can visit here to download Python.
Step 2. Write the following code
Write this code in a Python file or directly copy this code and save the file with the name and .py extension e.g python Tic_Tac_Toe.py
#cheat : high chance Win Strategy => 1 - 8 - 6 - 5 - 4
#libs
import os
#initialize
board = [' ' for x in range(10)]
FirstRun = True
#Game Modules
#insert tic tac toe symbol to screen
def insertLetter(letter,pos):
if(board.count(' ') >= 1):
board[pos] = letter
def spaceIsFree(pos):
return board[pos] == ' '
def printBoard(board):
print(' | | ')
print(' ' + board[1] + ' | ' + board[2] + ' | ' + board[3])
print(' | | ')
print('------------')
print(' | | ')
print(' ' + board[4] + ' | ' + board[5] + ' | ' + board[6])
print(' | | ')
print('------------')
print(' | | ')
print(' ' + board[7] + ' | ' + board[8] + ' | ' + board[9])
print(' | | ')
def isBoardFull(board):
if board.count(' ') >= 2:
return False
else:
return True

return(

if x.lower() == 'y' or x.lower() =='yes':
StartTheGame()
else:
print("GLHF")
breakStep 3. Run the code
After saving the code double-click on the file to run the program or simply open Command Prompt and write the following command.
