If you cant see the games it is because you need the Macromedia and Shockwave flash plugins for your browser which can be found at the links below..

The Macromedia Flash plugin can be found here.

The Shockwave Flash plugin can be found
here.

just download them and install the plugins to your broswers' plugin folder. it should be c:\program files\my browser\plugins

note: between these 2 plugins you should be able to access every game listed here.

Good Luck.
