Numbers /10,000
How rare is 10,000?
10,000 scores 812 and sits in the Singular tier — 1 in 5,650 of all supported numbers score this high or higher. Everything below is computed from a complete analysis of all 1,000,001 numbers in range.
RNGdle.net’s own rarity score. Top 0.02% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. How this differs from EP · Badge guide
These notes make the number easy to read, but they add no score unless a separately counted rarity signal appears below.
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
An integer squared.
Factorization · signal frequency
A number of four or more digits built from just two digits.
Repetition · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
A single digit appears exactly four times.
Repetition · signal frequency
Iterating the sum of squared digits reaches 1.
Arithmetic · signal frequency
Three or more identical digits in a row.
Repetition · signal frequency
Strongest signal: Digit sum 1. It appears in 7 supported numbers and contributes +342 after correlation decay.
Why is 10,000 unusual? Only 0.02% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Singular tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.

Patterns in this number
Each of these has its own page explaining how common the pattern is and why.
Quadruple Digits
A quadruple number contains exactly four copies of one digit, like 4441 or 727772. Four of a kind is the point where repetition stops looking like coincidence.
Adjacent Digit Runs
A run is three or more identical digits sitting next to each other, like the 777 inside 27773. Adjacency is what makes a run read as deliberate.
Numbers Built From Two Digits
These numbers use only two different digits across four or more places, like 9119 or 303033. The whole number is drawn from a two-symbol alphabet.
Harshad Numbers
A Harshad — or Niven — number is divisible by the sum of its own digits. 18 works because 1 + 8 = 9 and 18 ÷ 9 = 2.
Happy Numbers
Square each digit, add them up, repeat. If you eventually reach 1 the number is happy; if not, you fall into a cycle. 19 → 82 → 68 → 100 → 1.
Perfect Squares
A perfect square is some whole number times itself: 144 = 12², 10000 = 100². The range ends neatly on 1,000,000 = 1000².
