PatchSo, a Korean mobile-game update index

Field notes

PatchSo organizes Korean mobile-game activity around Google Play revenue-ranking coverage, recording release dates and classifying entries such as events, maintenance, and content updates. Its ranking comparisons use weekly snapshots, while its next-update estimate requires at least three prior release intervals and is explicitly presented as a statistical calculation rather than an official announcement. The homepage also breaks current activity down by genre and links to a calendar, game directory, statistics, reports, glossary, and correction history.
