Some of 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. If you are using an unsupported browser you will see the message "In order to play this game you must be using a browser that supports HTML5."
Which browsers support HTML5 games?
Edge (comes installed with Windows 10 only)
Safari (Mac only)
Make sure the browser is updated. See instructions for updating your browser.
Having trouble on a supported browser?
HTML5 games require certain graphics cards and drivers (the hardware used to play video graphics). Check for any available updates on your computer. If you still have trouble, your graphics card may not support HTML5.
