Check a number
Enter any supported value and matching pattern cards light up immediately. The EP and tier beside the input provide a quick link between structure and score.

PATTERN REFERENCE
Recognize the structures hidden inside a number
The Pattern Atlas checks familiar mathematical and digit-based structures, including palindromes, primes, repeated digits, unique digits, squares, powers of two, runs, Harshad numbers, and alternating digits.
Read exact counts
Each card shows how many values in the complete range match that pattern and the corresponding share of all possible numbers.
Build a daily collection
Saving the official daily specimen records the patterns found on that roll. Filters then separate collected structures from those still missing.
Patterns overlap, and that is part of the fun
One number can match several definitions at once. For example, a repeated-digit value may also be a palindrome, and a square can also be a Harshad number. Pattern counts describe each definition independently rather than dividing the range into exclusive groups.
The full verification button checks all 1,000,001 values in the browser and loads example numbers for each card. This can take longer on slower devices, but ordinary number checks and the stored counts are available immediately.
PLAYER QUESTIONS
Useful details before you start
Why does one number light up several cards?
The definitions are allowed to overlap. Every matching structure is shown, just as a number can earn several badges in the analyzer.
Does collecting a practice roll fill the atlas?
No. Only the saved UTC daily specimen advances the collection; manually checking a number is temporary.
