Quick Questions
Everything you might be wondering about
Can these pranks actually harm a computer?
Nope! Everything is purely visual. We're just showing pixels on a screen—nothing more. The computer is perfectly fine. Think of it like watching a movie; it's all just for show.
How do I stop a prank once it's running?
Press the ESC key or F11 to exit fullscreen. Some pranks also have specific exit instructions shown on screen. If all else fails, refreshing the page or closing the browser tab will do the trick.
Do these work on Macs too?
Absolutely! While we have Windows-specific pranks (like the Blue Screen), we also have universal ones like the Matrix rain or BIOS simulator that work great on any operating system.
Can I use these at work or school?
Technically yes, since nothing gets installed. But please be smart about it! Make sure your workplace culture is cool with pranks, and don't do anything that could get someone in actual trouble. When in doubt, maybe save it for home.
