RNGDLE Number Rarity Calculator
RNGDLE.ART is a free number rarity calculator that checks any integer from 0 to 1,000,000 against 31 exact digit patterns — including palindromes, repdigits, primes, Harshad numbers and Fibonacci numbers — and returns a rarity score plus a global percentile.

What is an RNGDLE rarity score?
The score measures information in a number's matched patterns, digit sum, distinct-digit count and short length within 0–1,000,000. Less frequent features usually contribute more, with overlapping features in the same family discounted.
Probabilities come from an exhaustive count of all 1,000,001 integers. Scores do not predict the next random result. Top % includes every tied score; a smaller percentage means a higher rarity ranking.
How scoring works →How to check your number
- Enter any integer from 0 to 1,000,000 above; leading zeros are not part of the analysis.
- Select Analyze to see the rarity score, Top % and matched patterns.
- Open a pattern to read its rule, or compare two numbers to inspect their differences.

What is an RNGDLE rarity score?
The score measures information in a number's matched patterns, digit sum, distinct-digit count and short length within 0–1,000,000. Less frequent features usually contribute more, with overlapping features in the same family discounted.
How rare is my number?
Enter any integer from 0 to 1,000,000 and select Analyze. The result shows its patterns, score and Top %: the percentage of all 1,000,001 integers scoring at least as high, including ties. A smaller Top % means a higher rarity ranking.
Are rare numbers less likely to be rolled?
No. In a uniform draw, each specific integer has probability 1/1,000,001. This tool measures uncommon features and cannot predict future results.
Is RNGDLE.ART the official tool for rngdle.com?
No. RNGDLE.ART is an independent number tool and browser game, unaffiliated with rngdle.com or any similarly named site. Its scores are not another game's scores or answers.
