To play the Engage games you need to install the Engage Browser "plug-in" and your choice of the games you want to play.  

The browser "plug-in" comes in Netscape and Explorer versions. Select the "Plug-in" option on the left and then press the approriate install button to start off the installation process. N.B. We recommend that you use a Netscape browser (and plug-in) for faultless game play.

Once you have installed the "plug-in", select and install any games that you want to play from the list on the left.
