SteamScope Score
Our proprietary quality index — one number that summarizes how well a game is holding its audience and community over time.
SteamScope Score is our proprietary 0–100 index of how a title is performing on Steam. It is recalculated on a regular schedule from SteamScope's own tracking pipeline and reflects live audience size, community health, recent momentum, and long-term staying power in one trusted number. Trend Score on the same page measures short-term movement separately.
