Numbers /13,331
How rare is 13,331?
13,331 scores 640 and sits in the Singular tier — 1 in 1,330 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 0.08% 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.
Reads the same forwards and backwards.
Symmetry · signal frequency
A number of four or more digits built from just two digits.
Repetition · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
Divisible only by 1 and itself.
Factorization · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Three or more identical digits in a row.
Repetition · signal frequency
A single digit appears exactly three times.
Repetition · signal frequency
Strongest signal: Palindrome. It appears in 1,989 supported numbers and contributes +179 after correlation decay.
Why is 13,331 unusual? Only 0.08% 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.

Each of these has its own page explaining how common the pattern is and why.
Triple Digits
A triple contains exactly three copies of one digit, such as 8188 or 636306. It is the most common form of strong repetition — and the first one most people notice.
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.
Palindrome Numbers
A palindrome reads the same forwards and backwards, like 12321 or 909. They are one of the most recognizable patterns a number can have.
Prime Numbers
A prime has no divisors other than 1 and itself. They are the building blocks every other number is assembled from.
