This online bridge feature needs Flash Player present on your computer.  Flash Player is almost always present on newer computers.  If Flash Player is missing on your computer you will just see a blank screen when you click the 'Play Now' button.

To test if you have the latest Flash Player click here.  If you get the message 'Installation Complete' everything is OK and you can close this window, otherwise it will tell you that you need Flash Player and provide a link from which you can download it.
