The way to get games running in a browser is to use Java Applets or Flash. The way they do it to run in a browser is that they are browser plugins. To do it like them, look up NPAPI (Netscape Plugin API) which works on all browsers except IE (as far as a know) and for IE you would use Microsoft:s ActiveX componenets.

But I would recommend Flash or Java.
