Numbers /888
How rare is 888?
888 scores 888 and sits in the Singular tier — 1 in 11,364 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 <0.01% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. 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.
Every digit is the same, like 777 or 444444.
Repetition · signal frequency
One of only 900 three-digit numbers in range.
Range · signal frequency
Reads the same forwards and backwards.
Symmetry · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
Divisible by the sum of its digits.
Arithmetic · signal frequency
Iterating the sum of squared digits reaches 1.
Arithmetic · signal frequency
Strongest signal: All digits identical. It appears in 45 supported numbers and contributes +289 after correlation decay.
Why is 888 unusual? Only <0.01% 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.
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.
Palindrome Numbers
A palindrome reads the same forwards and backwards, like 12321 or 909. They are one of the most recognizable patterns a number can have.
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.
Happy Numbers
Square each digit, add them up, repeat. If you eventually reach 1 the number is happy; if not, you fall into a cycle. 19 → 82 → 68 → 100 → 1.
