Numbers /1,031
How rare is 1,031?
1,031 scores 587 and sits in the Extreme tier — 1 in 848 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 0.12% 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
One of 9,000 four-digit numbers in range.
Range · signal frequency
Divisible only by 1 and itself.
Factorization · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Every comparison strictly alternates between rising and falling.
Sequence · signal frequency
Exactly one digit appears twice.
Repetition · signal frequency
Strongest signal: Digit sum 5. It appears in 252 supported numbers and contributes +239 after correlation decay.
Why is 1,031 unusual? Only 0.12% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Extreme 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.
Numbers With One Repeated Digit
The mildest form of repetition: exactly one digit appears twice, and every other digit is distinct — as in 1231 or 405067.
Zigzag Digit Numbers
Every comparison changes direction: up, down, up, down — or the reverse. In 792619 the path is 7 < 9 > 2 < 6 > 1 < 9.
Prime Numbers
A prime has no divisors other than 1 and itself. They are the building blocks every other number is assembled from.
