Free Prank Websites & Gag Tools

Harmless jokes that run in any browser: mind reading, rigged coin flips, fake lie detectors, disguised jumpscare links. No downloads, no accounts, and the link pranks land on a friendly reveal so nobody is left believing it.

Mind Reading Prank

Free mind reading prank website: the oracle answers any question your friends ask — because you secretly typed the answer while they watched you type the magic words. The classic Peter Answers trick, modernized.

Jumpscare Prank Link

Free jumpscare link to send to friends: pick an innocent-looking page — stare at the dot, an optical illusion, a riddle — set how loud the scare is, and it jumps out seconds later. Ends with a friendly reveal. No flashing lights, volume-capped.

Rigged Coin Flip

Free rigged coin flip: a coin that always lands on heads — or tails — because where you tap the flip button secretly decides the result. Looks completely fair to everyone watching. Win every toss, then reveal the gag.

Crystal Ball Mind Reader

Updated

The classic crystal ball mind reading trick online: think of a two-digit number, do the digit math, find your symbol in the chart — the ball reveals it every time. The old Flash Mind Reader, rebuilt for modern browsers.

Rigged Love Calculator

Free rigged love calculator prank: secretly arm the result before your friend types the names — ~8% disaster to ~96% soulmates, you decide. Honest name-hash otherwise, and names never leave the browser.

The Impossible Button

The button you can’t click: it dodges your cursor, taunts you after every escape, and finally surrenders into a friendly reveal. Play it yourself or send the disguised “claim your prize” prank link to a friend.

Rigged Dice Roller

Free rigged dice roller — loaded dice online: where you tap the roll button secretly decides the result, so the die always rolls 6 (or 1) while everyone sees a fair tumble. Keyboard presets pick exact faces.

Fake Lie Detector

Free fake lie detector prank that runs in the browser — no app to install. Friends press a thumb on the scanner and get TRUTH or LIE — verdicts you secretly queued up before handing over the phone.

Rigged Rock Paper Scissors

Free rigged rock paper scissors: your friend plays the computer, but you secretly decide who wins every round — it counters their every throw, always loses, or plays fair. Identical on screen either way. Best of 3/5 scoring and a practice mode.

Ghost Detector Prank

Updated

Free ghost detector prank that runs in the browser — no app to install, no camera. A radar sweep and EMF needle idle innocently until you secretly arm a detection: readings spike, a blip crosses the radar, and a spooky sting plays. You control the ghost.

Two Kinds of Prank, One Golden Rule

Everything here falls into two families. Link pranks travel through the group chat: you copy a disguised short link (no “prank” in the URL to spoil it), a friend opens it, and the joke plays out on their screen, ending on a “You got pranked!” reveal with a button to prank someone else. Accomplice gags happen in the room: the screen looks innocent, but you control it through invisible inputs: hidden typing in the mind reading oracle, tap zones on the lie detector’s title bar, the secret halves of the rigged coin flip button.

The golden rule holds for all of them: the reveal is the punchline. A prank that ends with everyone laughing gets passed on; a prank that leaves someone believing something false is just lying with extra steps. That is why the shareable pranks carry their own reveal (the jumpscare’s arrives seconds later, the impossible button’s the moment it gives up and lets itself be clicked), and every accomplice gag comes with a cheat sheet designed to be shared the moment the joke lands.

Deliberately Harmless

These pranks startle, baffle, and embarrass (briefly), but they were built with hard safety lines: no strobe or flashing effects, volume-capped synthesized sound, nothing that imitates a real company, virus warning, or system screen, and the pranks themselves download nothing and collect nothing. A prank from this page can be opened with total confidence, which is exactly what makes it work twice.

Pick the Prank That Fits the Room

Which one is funniest is the wrong question. The situation picks the prank, and three things sort it: whether you are there, whether anyone is in on it with you, and whether your victim ends up holding the phone.

  • You are not in the room. Two of these travel by link: the jumpscare and the impossible button. You copy a disguised link, they open it wherever they are, and the joke plays out on their screen. The impossible button is the gentler of the pair: it teases instead of startling, taunts them after each escape, and eventually surrenders and lets itself be caught.
  • You are there, and you keep hold of the device. The mind reading oracle is the pure performance: the secret lives in how you type, so your audience has to see the screen but must never take it. The rigged coin flip and the rigged dice roller work the same way, and the secret is where your thumb lands: the coin’s outer edges claim 80% of its button, the dice roller’s outer thirds two-thirds of its own, and those zones outrank the visible setting. There is also a visible middle-zone setting that survives a reload, but it only decides the taps the edges do not claim: a dead-centre hit, or a flip triggered from the keyboard. It is not a way to force a result and hand the phone over.
  • You are there, and they end up holding it. Arm it first, hand it over, and let the victim do the rest. The lie detector takes a queue of verdicts you script before the interrogation starts; rigged rock paper scissors keeps its armed mode across a whole best-of series from one innocent tap as you pass the phone; the ghost detector lets you stack several hauntings and then walk away; and the rigged love calculator wants arming before the names go in, because the rig fires once and then disarms itself.
  • Nobody is in on it with you. The crystal ball is the one that needs no accomplice and no link. It works on algebra rather than on a secret control, so there is no mistimed tap to give it away, and because every valid answer lands on the same symbol, a whole table can play at once and be right together.

Read the Room Before You Send It

The tools are harmless; judging the moment is still your job. A startle in a quiet office is not the same joke as the same startle in a group chat, and the person it is easiest to send something to is often the one who least enjoys it. Two things here make that judgement easier. Nothing goes off on its own: the ghost detector’s idle needle is capped below the level that would count as a detection, so a phone left face-up on a table stays a phone left face-up on a table. And a prank link is a loan rather than a trap: it stops working a day after you copy it and shows a friendly expired screen instead, so something you sent on a whim cannot resurface a fortnight later on someone’s worse day.

Learn the Trick, Become the Trickster

Every accomplice gag doubles as a how-to: the full secret (keystrokes, tap zones, practice mode) is documented on each tool page, kept in sync with the code that runs the trick. Victims become accomplices within minutes. That is the life cycle of a good prank, and we are here for it.

Frequently Asked Questions

Are these prank websites safe to use and share?

Yes, by design. The pranks install nothing and download nothing, nothing is recorded, no camera or microphone is used, and there are no flashing or strobe effects. Shareable pranks land on a friendly "You got pranked!" screen: nobody is left believing something false.

What is an accomplice prank?

A two-person gag: one victim, one accomplice who is in on it. The tool looks innocent (an oracle, a lie detector, a coin flip), but the accomplice controls it through a secret input (hidden typing, tap zones, keyboard presets). All seven accomplice tools carry a practice mode and a cheat sheet for the secret controls, kept in the same module as the trick it documents; rigged rock paper scissors carries two, one for the secret controls and one for what beats what. The link pranks and the crystal ball have neither, because neither has a secret input to rehearse.

Do the pranks work on phones?

All of them are built phone-first: pranks live in group chats and hand-me-your-phone moments. The link pranks fill the phone screen; the accomplice gags have touch-sized secret controls and fullscreen modes that hide the instructions from your victim.

Do any of these pranks make noise?

Three of them do. The jumpscare is the loud one. The lie detector beeps as the scan climbs and then delivers a two-tone verdict: a rising chirp for TRUTH, a low buzz for LIE, which is the loudest thing it plays. The ghost detector runs a geiger-style crackle that speeds up as the reading rises, then a sting when the presence lands. The rest (the oracle, the crystal ball, the rigged coin flip, the rigged dice roller, the love calculator, rigged rock paper scissors and the impossible button) are completely silent. Every sound you can hear is synthesized in the browser rather than played from an audio file, and the levels are deliberately conservative: the jumpscare’s loudest setting is capped short of clipping, so turning it up makes it louder but never harsher, and the detector cues are quiet by design.

Which prank can I do in a quiet room or a classroom?

Pick one where the joke is on the machine rather than on a person. The rigged coin flip and the rigged dice roller let a room call the toss and lose every time, and neither needs anything from you but where you tap. Steer clear of the ones that land a verdict on a particular person: the love calculator takes two names and scores the pair, and the lie detector calls whoever has a thumb on the scanner a liar in front of everyone. It never asks for a name, which is exactly what makes it land. The ghost detector has a Classroom sweep flavour with its own zone names (teacher’s desk, supply closet, back row), and the only name it takes is the ghost’s, but it crackles as the reading climbs and stings when the presence arrives, so save that one for a room where noise is fine.

Will you add more pranks?

When we find one worth building. Every prank here had to pass the same bar: harmless, browser-only, and genuinely funny. If a classic prank is missing, use the feedback button on any tool page and tell us which one; the best suggestions get built.
