Monthly data dumps of public games from RealGolf.Games, published in GGN format.
Dumps are published at database.realgolf.games on the first of every month.
Each file contains only the public games created in that specific month, one serialized GGN string per line, compressed with gzip.
Dumps are not cumulative. To reconstruct the full public dataset, download every monthly file.
YYYY-MM.ggn.gz
Games are stored in GGN (Golf Game Notation) — an open format inspired by PGN. See the GGN Specification for full documentation.
Use the official CLI to work with GGN files:
pnpm add -g swingalytica
swingalytica ggn -i 2026-07.ggnWhen using the data, attribution is required:
