Numbers /233
How rare is 233?
233 scores 884 and sits in the Singular tier — 1 in 10,753 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 <0.01% 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.

Factorization · signal frequency
One of only 900 three-digit numbers in range.
Range · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Divisible only by 1 and itself.
Factorization · signal frequency
Exactly one digit appears twice.
Repetition · signal frequency
Strongest signal: Fibonacci number. It appears in 30 supported numbers and contributes +300 after correlation decay.
Why is 233 unusual? Only <0.01% 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.
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.
Prime Numbers
A prime has no divisors other than 1 and itself. They are the building blocks every other number is assembled from.
Fibonacci Numbers
Each Fibonacci number is the sum of the two before it: 1, 1, 2, 3, 5, 8, 13 … reaching 832040 before the range runs out.
