Tic Tac Toe JavaScript Game With Source Code

Tic Tac Toe in JavaScript: We all know about this game, and we also played this many times. Today, I will show how we can create this game in some web languages like HTML, CSS & JS. Tic tac toe is a very simple game, But its programming is not. This javascript program tracks your moves for the next automatic move, This is quite complicated. You can call it a small AI built-in javascript.

It is made possible with JQuery ( A JavaScript Framework ). In this program also have JQuery UI for better style and user interface. Previously I had created Snake Game In JavaScript, But this program is difficult compared to snake game. I am sharing the source code of this tic tac toe game, then you can understand this program. Because I can’t explain to you this program in articles or writing. I can teach you in video or when you will front me. But this time I don’t have enough time for creating videos, but I hope I will share videos also in future.

Game In JavaScript

Yes, we can create small games in javascript for web & android also. JavaScript is a beast in web programming or web apps development. You can create very basic to advance programs with it. You can see many online games, they are in HTML5 canvas with JavaScript. Now this kind of programs creation become easy with JQuery. I had seen a personal portfolio website with a cool game & also with his qualification, I forget that websites name. You can search for “games with javascript” on google after that, you can find many this kind of stuff.

Tic Tac Toe JavaScript Game – Source Code

So there is the source code of tic tac toe game. You have to create 3 files for this program.

index.html

Create a file named “index.html” and put these codes given here below.

style.css

Now create a CSS file named “style.css” for decorating this program.

.cell{
  background-color: #0493ED;
  width: 200px;
  height: 200px;
  margin: 10px;
  font-size: 100px;
  color: white;
  text-align: center;
  line-height: 200px;
}
#main{
  min-height: 100%;
  min-height: 100vh;

  display: flex;
  align-items: center;
}

.cell{

background-color: #0493ED;

width: 200px;

height: 200px;

margin: 10px;

font-size: 100px;

color: white;

text-align: center;

line-height: 200px;

}

#main{

min-height: 100%;

min-height: 100vh;

display: flex;

align-items: center;

}

function.js

Final & main thing, Create a JS file named “function.js” for creating the whole AI program.
