RNGdle number analyzer: explore every detail of your number.

What the number analyzer reports

The result card shows the digit count, the digit sum, parity, whether the value is prime, whether the string is a palindrome, how many distinct digits it contains, its distinct prime factors, and the tracked patterns it matches. The calculator shows the same card, so the two pages are interchangeable for the analysis itself; they differ in framing rather than in output.

Reading the digit story in order

Start with the digit count, which tells you how long the string is after leading zeroes are removed. The digit sum is the next useful signal because it carries divisibility information. The unique-digit count then separates numbers that reuse digits from numbers built from distinct ones, and the palindrome flag answers a question about order rather than about the digits themselves.

Worked examples you can verify

97 has two digits, a digit sum of 16, is odd and prime, and is not a palindrome. 12321 has five digits and a digit sum of 9, so it is divisible by 9, and it is a palindrome built from three distinct digits; its distinct prime factors are 3 and 37. 482913 uses six different digits with a digit sum of 27, which again makes it divisible by 3 and by 9. 1000000 is even with a digit sum of 1, and its distinct prime factors are 2 and 5.

Divisibility shortcuts worth knowing

A digit sum divisible by 3 means the number is divisible by 3, and the same test with 9 works for divisibility by 9. The final digit decides divisibility by 2, 5 and 10. These rules are why the digit sum matters more than it first appears, and they let you confirm part of the result card without a calculator.

Same engine, same answers

Every tool in this toolkit shares one calculation engine and version. Whatever the analyzer reports for a number is exactly what the calculator, sandbox and near miss finder report for it, which makes results reproducible across pages and means a figure quoted from one page can be checked on another.

What the analyzer does not do

It does not add fields the calculator lacks, and it does not reorder results into a different reading. Above all it does not translate a mathematical property into an official value: no EP, no rarity tier and no badge verdict is produced here, because the game's rules for those are not published in enough detail to reproduce.

Why the engine version is printed

Every result card states the engine version that produced it. That line exists so a figure can be traced: if a definition ever changes, the version changes with it, and a result quoted from an older page can be recognised as belonging to an earlier definition set. It is also why this site never adjusts a published count silently — a change to a definition would be visible on the card rather than buried in a release note.

Turning a result into a next step

A single analysis answers one question, and the useful follow-ups are already one click away. If the digit sum surprised you, the rarity page shows how often that pattern occurs across the whole range. If you want to know how close a value came to matching something, the near miss finder compares it with its neighbours. And if the number arrived as text, the share decoder extracts it so you can analyse it without retyping.

What does the digit sum tell me?

It is the total of the individual digits, and it also reveals divisibility by 3 and 9: if the digit sum is divisible by 3 or 9, so is the number.

How large a number can it handle?

The supported range is 0 to 1,000,000, matching the range the public RNGdle About page describes. Longer input is rejected instead of truncated.

Are results identical to the calculator page?

Yes. Both pages use the same engine version and show the same result card, so the same input produces the same output, including the pattern list and the frequency figures underneath it.

Does the analyzer show a first or last digit field?

No. The card reports digit count, digit sum, parity, primality, palindrome status, unique digits and factors. First or last digit has to be read off the number itself.

Why does unique digits matter?

It separates numbers that reuse digits from numbers built from entirely distinct ones, which is the property behind patterns such as repeated digits. A count equal to the digit count means no digit appears twice.

Can I check a number against an official rarity?

No. Rarity and EP are the game's, and the rules behind them are not published. The analyzer reports mathematical properties and marks anything official as unverified rather than estimating it.

What are distinct prime factors?

The prime numbers that divide the value, each listed once. 482913 is divisible by 3 and 9, and its prime factorisation starts at 3; a prime value lists only itself, and 1 never appears.

Which tool should I use first?

The analyzer if you want the digit-level reading, the calculator if you want the pattern frequency table beside the result, and the sandbox if you intend to change one digit and compare the outcome.

Can I analyse a number without typing it?

Yes. Open a shared link and the value is prefilled, pick a number from the recent list, or paste a labelled message into the share decoder to extract the digits first.

What happens if I enter a number with leading zeroes?

They are removed before analysis, so 000123 is reported as 123 and produces exactly the same card. The digit count reflects the canonical value rather than the characters you typed.

Can I keep a result for later?

Yes. Analysed numbers join the recent list in this browser on this device, so you can reopen one with a click. Nothing is uploaded, and clearing this site's browser data removes the list.
