Prank screens
Four harmless full-screen pranks for a friend’s computer or phone — each one leaves with a single press of Esc or a tap on Exit, and nothing on the device is touched.
Press Esc or the Exit button in the corner to leave at any time.

Frequently asked questions
Are these pranks safe?
Yes. Each prank is only a web page drawn in full screen. It does not install, change, delete or send anything, and it cannot affect the device, its files or its settings. The virus scan is a deliberate parody: it lists silly findings such as cat videos and ends with a large “Just kidding!”, and it never shows phone numbers, payment requests or instructions to do anything.
How do I exit the full-screen prank?
Press Esc on a keyboard, or tap or click the small Exit · Esc button in the bottom-right corner, which stays visible on every prank. F11 also leaves full screen in most desktop browsers. On a phone, swipe down from the top or use the back gesture; closing the tab always works too. Once full screen ends, the prank closes with it.
Does the fake update look like Windows or macOS?
No, on purpose. The update screen is a generic design of its own — a progress ring on a dark background with neutral wording — and it uses no operating system’s logo, colours, fonts or messages. It is convincing because it moves slowly and pauses now and then like a real installer, not because it copies anyone.
How does the cracked screen work?
The cracks are drawn fresh every time: radial cracks spread out from the impact point with small random turns and branches, joined by short ring-shaped fractures and a few chips right at the centre. They appear over black (like a phone that has gone dark), white or a photo you choose, such as a screenshot of your friend’s home screen. The photo stays on your device and is never uploaded. Every tap adds a new impact, with an optional glass-crack sound.
What happens when the fake update reaches the end?
You choose. Stick at 99% keeps it one percent short of finishing forever, which is the classic prank. Reach 100% then Just kidding shows a friendly reveal that nothing was installed. Start again from 0% loops endlessly. The time setting controls how long it takes to crawl from 0 to the end, from 1 minute to an hour.
Will the screen go to sleep during the prank?
The page asks the browser to keep the screen awake while a prank is showing, using the Screen Wake Lock API. Current Chrome, Edge, Safari and Firefox support it, but battery saver or an older browser can refuse, in which case the screen may still dim after the device’s normal timeout.
About this tool
These prank screens are light-hearted full-screen pages for fooling friends, family or co-workers for a moment. The fake system update shows a slowly filling progress ring that pauses now and then and can stop at 99% indefinitely. The cracked screen draws realistic shattered glass over a dark, white or photo background. The hacking screen fills the display with scrolling green code, stage-by-stage progress bars and a flashing ACCESS GRANTED. The virus scan parody runs a bright, cartoonish scan that finds cat videos and dad jokes before saying Just kidding.
Every prank is designed to be harmless and easy to end. A small Exit · Esc button stays in the corner of every screen, Esc closes the prank at once, and leaving full screen by any route ends it too. The virus scan is intentionally obvious: it uses playful colours rather than warning signs, and it never shows phone numbers, payment requests or instructions to call anyone — the kind of fake alert that scammers use is exactly what this page avoids. Please do not use any prank to scare, deceive or pressure someone.
A few tips make them land better. Set a delay of a few seconds so you can walk away before the prank appears. For the cracked screen on a phone or tablet, use a screenshot of the home screen as the photo so the cracks look like they are on the real display. On the hacking screen, type your friend’s name or computer name as the target. The update screen is best with Stick at 99% and a time of 5 to 10 minutes.
Everything runs locally in your browser. Nothing is uploaded, a chosen photo stays on your device, and no information about the device is collected. The IP addresses on the hacking screen come from ranges reserved for documentation, so they never point to a real computer. When your device asks for reduced motion, blinking text stays still and the hacking log scrolls more slowly.
