Playtime is that of people who reviewed, from the 100 reviews SteamPeaks sampled for The Devil's Calculator: their total hours when the sample was read, and the hours they had when writing (the refund-window share). Reviewers have usually played more than owners who never wrote a review. Recomputed daily. How this is computed. Data by SteamPeaks.com.
Quieter than 100% of puzzle games at month 89.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Feb 2019 to Jul 2026, each month divided by the launch level (11). The band is the 25th to 75th percentile of puzzle games at each month since launch (131 games at launch); the half-life is the first month under half, counting from the month the launch level was set. No projection: the cohort has no curve twelve months beyond this game’s age. Recomputed weekly, last on 10 Oct 2026. How this is computed. Data by SteamPeaks.com.
