🏆 Primedle Leaderboard

How the Primedle leaderboard works

The Primedle leaderboard ranks one thing: how few guesses it took you to find the day's four-digit prime. Everybody is hunting the same number, so a three-guess find means exactly the same thing on every row, and the only tie-break is who got there earlier in the day.

Guesses that Primedle refuses never reach the board. Because a guess has to be prime itself, typing a number that is not costs you nothing — the attempt is simply not spent — so nobody on the Primedle leaderboard is being punished for a typo or a near miss on primality.

What it takes to place on today's Primedle leaderboard

Three is a good day and four is the common result, so anything at three or better puts you comfortably in the upper half. The scale runs:

Know more primes

This is the part of Primedle that genuinely rewards study, and the return comes quickly. Players who can rattle off primes in the 1000s and 6000s spend their guesses on tests they chose; players who cannot spend them on the first legal number they can think of. Over a week the difference on the Primedle leaderboard is about one guess per board.

Test digits, not neighbourhoods

The arrow tempts you into treating Primedle as a range search. Resist it. Eight distinct digits across your first two guesses will tell you more than any amount of narrowing, and the arrow is still there afterwards to separate the last two candidates.

Play early

Ties are common — several players will find today's prime in three — and they break on time. Playing soon after the reset is the cheapest position on the Primedle leaderboard there is.

Reading a row on the Primedle leaderboard

Each row carries the player, the prime they were hunting, the number of guesses it took and the EP that converts to. The prime is the same on every row, which looks redundant until you notice what it is for: a glance down the Primedle leaderboard tells you whether today's answer was a number with four distinct digits or one with an awkward repeat, and that explains most of the spread in the results below it.

Rows can be liked, and on the Primedle leaderboard a like usually means one of two things — either somebody found the prime in two, or somebody found it in six after a visibly terrible start. Your own row is highlighted wherever it lands, so there is no hunting for your name in the list.

One thing the Primedle leaderboard deliberately does not show is which primes other players guessed on the way. Publishing those would turn the day into a race to refresh rather than a puzzle, and would hand late players a shortcut the early ones never had.

Why some Primedle days are much harder

The spread of results on the Primedle leaderboard varies more than in most daily games, and the cause is almost always the shape of the answer rather than its size. A prime with four different digits gives up information on every guess, because each tile is an independent fact. A prime with a repeated digit does not: an amber tile could mean one copy or two, and the ambiguity costs most players an extra attempt.

The other hard case is a prime whose digits are all common openers. If the answer is built from 1, 3, 7 and 9 then almost every sensible first guess comes back mostly amber, which feels encouraging and narrows very little. Days like that fill the Primedle leaderboard with fours and fives, and a three is worth considerably more than it looks.

The week, all-time and badge boards

Today is one of four Primedle leaderboard views, and the other three reward completely different behaviour. This week totals seven days of EP, so never missing a board beats one brilliant morning — even a six-guess find banks 2,000, and seven of those outscore a single two-guess day followed by six blanks.

All-time does the same over your whole history and is therefore a measure of longevity rather than skill. Badges steps outside Primedle entirely and ranks collectors across every game on the site, so it is the one board a Primedle regular cannot climb without playing RNGdle as well.

Finishing any Primedle board also keeps the streak you carry across the whole site, which for most players turns out to be the number they actually care about. New to the game? The how to play guide explains the two feedback channels and why every guess has to be prime.

Other daily leaderboards

Every game here has its own board, all resetting together at midnight UTC, and one streak runs across all of them.
