Repeating Digit Numbers

One digit, committed to the bit.

What is it?

Repeating-digit numbers hammer the same digit again and again. Full repeats like 444444 are called repdigits; shorter streaks are runs — three in a row (48882), four in a row (77770), or five-plus, which RNGdle calls a monster run. The longer the streak, the rarer it is.

How it scores

Only your longest run scores, so a monster run never double-dips as a triple run too. Repdigits are extremely rare — just 45 exist in the whole range — and earn close to the per-trait score cap on their own.

The formula: -log2(count / 1,000,001) bits per trait, capped at 20, summed with 0.5 decay per additional trait.

FAQ

What is a repdigit?

Short for "repeated digit" — a number like 333 or 888888 where every digit is the same.

Does 1111 count as a repdigit and a run?

It is a repdigit, and repdigits score separately from runs, so you get credit for the full repeat rather than the streak inside it.

How rare is a monster run?

Runs of 5+ identical digits show up in well under 0.1% of the range — roughly one number in every few thousand.
