Repeating Digit Numbers
A repdigit is a number whose digits are all the same, such as 7, 77, 777 or 444444. They are among the rarest visual patterns because every digit is locked to one value.

1 in 22,222.2 per roll · 22,222 rolls on average.
At one daily specimen a day, the mean is about 60.8 years. A 50% chance takes 15,403 rolls; 90% takes 51,168.

Waiting times are averages, not deadlines. Previous misses do not increase the next roll’s chance. Only Daily Specimens stamp your Atlas.
There are only a handful of repdigits at each length — nine per digit-length, one for each non-zero leading digit — so across the whole range they are extremely scarce. That scarcity is exactly what the rarity score rewards.
Repdigits belong to the repetition group. Because RNGdle.net de-duplicates related traits within a group, an all-identical number scores from its strongest repetition trait rather than stacking every overlapping one.
Landing a repdigit in the Infinite Roll simulator is a genuine event — the probability simulator can estimate how many rolls a target tier like this typically takes.
Highest-scoring examples
The best-scoring numbers of four digits or more that carry this pattern. Shorter numbers are excluded here because their length alone dominates any score ranking.

Related repetition patterns
Five or More of One Digit
Five of a kind: one digit appears at least five times in the number, as in 888880 or 292222. Only six-digit numbers can reach this without being a full repdigit.
Quadruple Digits
A quadruple number contains exactly four copies of one digit, like 4441 or 727772. Four of a kind is the point where repetition stops looking like coincidence.
Triple Digits
A triple contains exactly three copies of one digit, such as 8188 or 636306. It is the most common form of strong repetition — and the first one most people notice.
Double Pair Numbers
A double pair has two different digits appearing twice each, like 3388 or 271721. It is the digit equivalent of two pair in poker.
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.
