In order to play games you need to add a student. The games can only be played from the student account.
The games require adobe flash to run. Unfortunately adobe flash is being phased out by most browsers but it is still possible to use it. I would recommend using a non-apple device (apple will not run flash at all) and Chrome as your browser. To enable flash in chrome, please check out this article.
We are in the process of updating the games so that they will run on all browsers.
