Numbers /2,100
How rare is 2,100?
2,100 scores 625 and sits in the Singular tier — 1 in 1,163 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 0.09% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. Same-length rank keeps the score and compares only numbers with 4 digits, including ties. 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
Contains a run of three or more consecutive descending digits.
Sequence · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
Exactly one digit appears twice.
Repetition · signal frequency
Strongest signal: Digit sum 3. It appears in 56 supported numbers and contributes +282 after correlation decay.
Why is 2,100 unusual? Only 0.09% 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.
Descending Digit Runs
Three or more digits each one lower than the last, appearing anywhere in the number — the 543 inside 15432, for instance.
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.
