- Its ranking counts all 1,000,001 supported integers; tied scores are included in the displayed top-percentile.
Field notes
The scoring explanation combines matched patterns, digit sum, distinct-digit count, and short length, while discounting overlapping features within a family. The ranking treats every supported integer as equally likely and includes all numbers tied at a score; the site explicitly says the score does not predict a future random result.
