Hey friends, today in this blog you'll learn how to create a Tic Tac Toe Game using HTML CSS & JavaScript. Earlier I have shared a blog on how to create Quiz Web Application using JavaScript and now it's time to create Tic Tac Toe Game using pure JavaScript.

In our program or design [Tic Tac Toe Game], at first, on the webpage, there is a selection box with the game title and two buttons which are labeled as "Player(X)" and "Player(O)". Users must select one option or button to continue the game. If the user selects the X then the bot will be O and if the user selects the O then the bot will be X. Once the user selects one of them then the selection box will be disappeared and the playboard is visible.

In the playboard section, there are the player names at the top and it indicates or shows whose turn is now. At the center of the webpage, there is a tic tac toe play area with nine square boxes. Once you click on the particular box then there is visible a sign or icon which you have chosen on the selection box. Once you click on any box then after a couple of seconds the bot will automatically select the box which is not selected by you or the bot before, and the opposite icon is visible there means if your icon is X then the bot will have O.

Once a match won by someone then the playboard section will be hidden and the result box appears with the winner sign or icon and a replay button. If no one wins the match and all nine-box selected then again the playboard section is hidden and the result box appears with "Match has been drawn text" and a replay button. Once you click on the replay button, the current page reloads and you can play again. Actually, the bot of this game is no clever and intelligent and I did use the minimax algorithm in it so you can easily win the match but from the source codes of this game, you can learn many more things.

You can copy the codes from the given boxes or download the code files from the given link but I recommend you to download the source code files instead of copying codes. Click here to download code files.
