Our new Math games use HTML5 (an alternate method of displaying videos and graphics online, which does not require Adobe Flash Player). These games have different requirements than Flash games. HTML5 games require certain graphics cards and drivers (the hardware used to play video graphics). If we are unable to load the games on your browser, you will see the message "In order to play this game you must be using a browser that supports HTML5." Depending on your computer, you may also see a blurred screen or the game loading as a black box. You can follow these troubleshooting steps:
- Make sure the browser is updated. See instructions for updating your browser.
- Check for any available updates on your computer. See instructions on turning on Windows updates here, or Mac updates here.
- Try clearing your cache. See instructions.
- Try using another browser. The following browsers are supported:
Edge (comes installed with Windows 10 only)
Safari (Mac only)
If you still have trouble, your graphics card may not support HTML5.
If you need assistance, please email us. Please let us know what kind of trouble you are having and which troubleshooting steps you have already tried.
