How rare is 636?
636 scores 668 and sits in the Singular tier — 1 in 1,570 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 0.06% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. Same-length rank keeps the score and compares only numbers with 3 digits, including ties. How this differs from EP · Badge guide
