Guess the PIN: the website the internet guesses together

Guess the PIN is a single-purpose website that picks one random four-digit code and invites the entire internet to guess it, one attempt at a time, until somebody lands on it. It is part guessing game, part slow-motion experiment in how strangers reach for numbers, and the running scoreboard is the real attraction.

In brief

• The site holds a single random four-digit PIN and lets any visitor guess it. When someone gets it right, a confetti animation plays and a new PIN is selected.
• According to its own statistics page, the site launched on September 8, 2021 and has logged more than 76 million guesses, with fewer than five thousand PINs actually solved.
• The most common guess is 1234, which the site records at just over 2 percent of all attempts, followed by 0001, 1111, and 0000.
• It was built by Bored Button LLC, and most of its traffic arrives from the same team's random-website button, which shapes the odd results.

What Guess the PIN actually is

The premise fits in a sentence. A hidden four-digit number sits on the server. You type four digits, press a button, and the site tells you whether you matched it. That is the whole interface: one input box, one button, and a counter.

There is no account, no score attached to your name, and no leaderboard of players. Everyone who visits is guessing at the same PIN at the same time. The game is collective by design. You are not racing other people so much as adding your attempt to a shared pile, and the pile is enormous.

The front page keeps a live tally of how many times the current PIN has been guessed incorrectly. On a recent visit it read more than 78,000 wrong guesses in the span of about five days, which gives a sense of the steady, anonymous traffic the site absorbs without ever asking for anything in return.

The design is deliberately plain. A serif headline, a single number field, a blue submit button, and below it the statistics that turn a one-off gag into something you can watch over time. Nothing animates, nothing nags, and nothing tries to keep you there. The page loads, states its one job, and waits.

How the game works

The mechanics are spelled out plainly on the site's own FAQ. The site randomly selects a four-digit number. Visitors guess until someone gets it right. Then it randomly selects another four-digit number and starts over. That loop has been running, uninterrupted, for years.

Ask what you win for guessing correctly and the FAQ answers with a straight face: a confetti party. There is no cash, no badge, no permanent record of your victory beyond the moment the animation fires. The reward is the small civic thrill of being the person who happened to be typing when the odds finally broke.

The FAQ also lays out the point of the exercise. First, to have some fun. Second, to track the results and see what can be learned from them. That second goal is where the site quietly becomes more interesting than its one-box interface suggests.

The tone throughout is light. When a visitor asks whether it is a PIN number, the FAQ gently refuses the phrase, pointing out that would make it a personal identification number number. That willingness to answer a silly question with a sillier straight face sets the register for the whole project.

The numbers so far

The statistics page is the heart of the project. It reports that since the launch on September 8, 2021, visitors have made more than 76 million total guesses. Against that, only 4,669 PINs had been correctly guessed by the time of this writing. On average, the site says, it has taken more than 16,000 guesses to solve a single PIN.

The site is candid about a limitation in its own record keeping. For database performance reasons, it stopped tracking individual guess counts for a PIN after one million attempts. The totals are real, but the counting has a ceiling, which is the sort of honest footnote that most polished products would bury.

Those headline figures reward a little arithmetic, which the next section does. On their own they already tell a story of scale: tens of millions of idle keystrokes, aimed at a target only ten thousand values wide, producing a trickle of solved codes measured in the low thousands.

The math of a shared guess

A four-digit PIN has 10,000 possible values, from 0000 to 9999. If the hidden number is truly random and guessers never repeat each other, you would expect to need somewhere around 10,000 tries to stumble onto it, give or take. The site's reported average sits higher, near 16,271 guesses per solved PIN.

That gap is the interesting part. Guesses are not coordinated and they are not evenly spread. Thousands of people independently try 1234, 0000, and 1111 before anyone works through the dull middle of the range. Collisions waste attempts. The crowd keeps re-checking the same memorable doors while the plain ones stay shut, so the real cost of cracking a PIN runs well above the tidy theoretical figure.

It is a small, legible demonstration of a larger idea: a crowd with no coordination is not the same as a systematic search. Ten thousand people guessing at random cover the space far less efficiently than one patient person counting upward would.

There is also a survivorship quirk worth naming. Because the counter only advances on wrong guesses, every number you see on the front page is a record of failure. The one correct guess that ends a round barely registers before the PIN resets. The site is, in effect, a monument to near misses, which is a fitting shape for a game that almost everyone loses.

Why the solved count stays small

Set the two big numbers side by side and the contrast is stark. More than 76 million guesses have produced fewer than five thousand solved PINs. That ratio looks grim until you remember the denominator: each round needs the crowd to land on one exact value out of ten thousand, and the crowd keeps wasting its energy on the same famous handful.

The launch timeline, visible in the dates on the site's blog, shows how early the project found its rhythm. The site went live on September 8, 2021. By September 19 it had fielded its first visitor question about guess times, and by September 27 it had already published its analysis of common patterns. The experiment was interpreting itself within three weeks, and it has simply kept accumulating data ever since.

What the guesses reveal

The most-frequent-incorrect-guesses table is the part people linger on. The statistics page ranks 1234 first, logged at about 2.04 percent of all guesses, or roughly one in every fifty attempts. Behind it come 0001 at 1.51 percent, 1111 at 1.08 percent, and 0000 at 0.94 percent. The pattern is immediately familiar to anyone who has ever set a lazy passcode.

The site's own blog sorts these habits into three buckets. The first is sequential digits: 1234 leads, but 2345, 3456, 4567, and 5678 all show up, as if people are walking their fingers up the keypad. The second is sequential counting from zero: 0000, 0001, 0002, 0003, the signature of someone deciding to brute-force the range in order. The third is repeating digits: 1111, 2222, 3333, and 9999, easy to remember and, as the blog dryly notes, easy to guess.

The blog even tracks the sequential run past the top ten. After 1234 and 2345, the pattern continues with 3456 at about 0.33 percent, 4567 at 0.28 percent, and 5678 at 0.21 percent, a clean decaying staircase. People who start walking up the keypad tend to do it the same way, and the frequencies fall off in near-perfect order.

One statistic from that post stands out. The ten most-frequently incorrect guesses represent just 0.10 percent of all possible four-digit numbers, yet they account for 8.08 percent of the guesses actually made. A tiny sliver of the number space soaks up a large share of human attention. The rest of the keypad goes comparatively ignored.

Why the clock and the counter disagree

The statistics page also keeps a history of solved PINs, listing how many guesses and how much time each one took. Read it closely and something strange appears: the two columns barely track each other. One PIN might fall after 8,800 guesses in ten minutes, while another needs a similar number of guesses but takes five hours.

A visitor noticed this and wrote in, and the site answered in a blog post. The explanation is traffic, not difficulty. Almost all of the site's visitors arrive through Bored Button, the random-website button run by the same team. That source is bursty and uneven. A PIN that happens to be active during a flood of visitors gets guessed quickly in clock time, even if it takes many attempts. A PIN unlucky enough to sit during a quiet stretch lingers for hours on far fewer visitors.

It is a small point, but it reframes the whole scoreboard. The times on the page are not a measure of how hard a number is to guess. They are a measure of how much traffic was passing through at that moment, which makes the history less a difficulty chart and more a faint seismograph of the site's own popularity.

What it says about real PIN security

Guess the PIN is a toy, and it is careful to say so. The FAQ warns, in plain language, against guessing your own real PIN on the site, and advises never entering a PIN anywhere but at a secure ATM. That caution is worth repeating: the game is a curiosity, not a place to test your bank card.

Still, the data gestures at a well-documented truth about how people choose numbers. In 2012 the data scientist Nick Berry, writing at DataGenetics, analyzed a set of about 3.4 million leaked four-digit passwords and found that 1234 alone accounted for roughly one in nine of them, with 1111 and 0000 close behind. Real chosen PINs are even more lopsided than the guesses on this site.

The comparison is instructive. On Guess the PIN, 1234 is only about 2 percent of guesses, because guessing a random target and choosing a memorable code are different acts. When people pick a PIN to remember, they crowd onto a handful of patterns far harder. When they guess at a hidden one, they spread out a little more, probing sequences and repeats.

Both behaviors point the same direction. The obvious numbers are obvious to everyone, which is exactly why they make poor secrets. A passcode that feels natural to you almost certainly feels natural to a stranger, and the table on this site is a gentle, anonymous reminder of how crowded the front of that queue really is.

The quiet pleasure of a shared counter

Part of the appeal is that you are never guessing alone. The counter on the front page is proof that thousands of other people are poking at the same locked box, most of them moments before or after you. There is a low, companionable hum to it, a sense of joining a line that formed long before you arrived and will outlast your visit.

It also scratches a familiar itch without the usual cost. The dopamine of a slot machine comes from the near miss, and Guess the PIN is almost all near miss. The difference is that it takes nothing when you lose. No money changes hands, no streak is broken, and no notification chases you later. You simply type four digits, watch the number refuse you, and get on with your day.

Who made it and where it sits

The footer credits Bored Button LLC, and the lineage shows. Bored Button is a long-running single-purpose site whose entire function is a button that throws you at a random corner of the web. Guess the PIN reads like a companion piece: another small, self-contained idea built to run forever and reward idle curiosity rather than engagement metrics.

That places it in a familiar tradition of single-serving websites, pages that do exactly one thing and refuse to grow into anything larger. It keeps company with other guess-driven toys this blog has covered, from Semantle, which asks you to guess a hidden word by meaning, to the doodle-reading Quick, Draw! The appeal is the restraint. There is no feed to scroll, no profile to fill in, no next episode queued up. You arrive, you guess, you watch the counter tick, and you leave, which is a pace worth defending.

For a different flavor of the same slow-internet spirit, the Bureau of Very Slow News delivers each story only once enough time has passed to be sure it mattered. Both sites share an instinct that the web does not have to be urgent to be worth visiting, and that a page can keep its promise by doing less, not more.

Guess the PIN rewards a particular kind of attention. Spend two minutes and it is a mildly amusing lottery. Spend ten reading the statistics and blog, and it turns into a tidy little study of how crowds behave when handed a trivial task and no instructions. Either way, it asks nothing of you and keeps no record of your visit, which in the current web counts as a small act of generosity.

FAQ

Is Guess the PIN safe to use with my real bank PIN?

No, and the site itself says so. Its FAQ explicitly advises against guessing your own PIN and tells visitors never to enter a PIN anywhere except a secure ATM. Treat the game purely as a curiosity and type random numbers, not anything tied to your accounts.

What do you win if you guess the PIN correctly?

A confetti animation. There is no money, badge, or lasting record. Once the correct guess lands, the site celebrates briefly and then selects a brand new random four-digit PIN, and the collective guessing starts over from scratch.

What is the most commonly guessed PIN?

According to the site's statistics page, it is 1234, recorded at about 2.04 percent of all guesses, or roughly one in fifty. The next most common guesses are 0001, 1111, and 0000, a mix of sequential and repeating digits that mirrors how people choose easy codes.

Who built Guess the PIN?

It is made by Bored Button LLC, the same team behind Bored Button, the random-website button. Most of the site's traffic arrives through that button, which the makers say explains the uneven times recorded for solving different PINs.
