Three-day maxima, not averages or daily unique players. Periods use UTC; the last source period is incomplete. Historical zero-filled samples are ambiguous and shown as gaps. Values are approximate tiers. Bars at date-range edges may represent a partly visible full source period; the listed dates and tooltip identify the complete aggregation interval.

    N New label observed

    The recorded Poki feed provides new-label observations only; hot and staff-picked observations are not available from this source.

    Markers are positive daily observations from the portal API, not entry or exit dates or continuous placement. Hot does not prove a popular-list position; staff-picked does not prove homepage placement. These observations do not establish a cause for popularity changes.

    No recorded label observations in this range. This does not prove that the game was never listed.
