How do I provide embed code for my web game?

I built a browser game and I want to make a button when user click it he get embed code for his site and my game will work on other sites. (Similar to YouTube's embed code). Is it possible?

You must use Iframe.

See Youtube's embed code:

<iframe width="560" height="315" src="https://www.youtube.com/embed/IDVIDEO" frameborder="0" allowfullscreen></iframe>

You export your game from C2 with Export HTML5 / Embed style

On your server, you upload your game http://www.mywebsite.com/MYGAME/

Then, you write a html code like:

<iframe width="width_you_want" height="height_you_want" src="http://www.mywebsite.com/MYGAME/" frameborder="0" allowfullscreen></iframe>

And you put it on your html page.

cool!!!
