Add Tic-Tac-Toe To a Webpage

Let your visitors play Tic-Tac-Toe game on your Blogspot/blogger blogs! We created and played with tons of widgets and plugins now its time to add some spice to your normal work. Engaging readers in an interactive activity like a game will help decreasing down your page bounce rate and will also provide fun to your regular readers or blog visitors. I cam across a simple javascript that uses array to program a simple tictactoe game where a visitor can play with computer bot. The consists of a total four levels with increasing difficulty level. The game uses artificial intelligence to guess important moves to knock a player down. The scores are saved for each level and the total number of wins and draws are recorded for both the computer player and your visitor. I guess this would surely be welcomed by all your visitors. :p

Live Demo

I have edited the codes and this code is working fine both with HTML/Javascript widget and blogger post editor. The installation process is extremely simple.

How to install Tic-Tac-Toe on Blogger?

We simple need to paste a large chunk of code inside the editor in order to embede the game inside a website or webpage.

1. Go to Blogger > Create New Post
2. Give your Post a title
3. Add the following code inside the Edit HTML section of your blogger post editor
