Frequently Asked Questions
Is PrankSims safe to use?
Yes. Every prank runs entirely in your browser and does nothing to your computer. No files are deleted, no malware is installed and no system settings change. It is 100% visual trickery.
How do I send a prank to a friend?
Pick a prank screen, copy the URL from your browser's address bar and send it to your friend. When they open the link, the prank loads instantly and goes fullscreen.
How do I exit a prank screen?
Press the Escape key or the Q key at any time to leave the prank and return to the PrankSims home page. On a phone or tablet, swiping out of fullscreen or using the browser's back button also works.
Is PrankSims free?
Yes. PrankSims is completely free with no account or sign-up. Just pick a prank and share the link.
Do the pranks work on phones and tablets?
Yes. The screens run in any modern browser on Windows, macOS, Linux, Android and iOS. Some mobile browsers limit fullscreen, in which case the prank fills the visible page instead.

PrankSims has fake Windows updates from 3.1 to 11, blue screens of death, macOS, iOS, Android, Ubuntu and ChromeOS updates, ransomware screens like CryptoLocker, WannaCry and Petya, hacker terminals, tech support scams, cracked and broken screen effects, and absurd comedy screens.
