How to use the online pranks?

Wait for your victim to leave his computer unattended and open a prank. Activate full screen with the F11 key to hide the browser frame and the web address bar. Wait for your victim to return to his machine and watch his reaction.

Some pranks also work if you just call someone over to watch you using it on your device. Ask for help from a colleague to help you fix your broken computer.

You can open the pranks, interact with the programs and do great things. Go ahead and explore them clicking around! They work best on a desktop computer or at least on a tablet because most mobile web browsers don't allow us to activate full screen mode.
