Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Badge funnel

[ SINGLEPLAYER ] - Defeat Baldi · progression46 · 0.00% win

2025 - Halloween · other7 · 0.00% win

How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.

Like ratio over time

Growth

2 measurements spanning 10 days. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 90–92 and does not start at zero.

Percentage of votes that are likes, at each of our measurements. A falling line is a game losing its crowd’s goodwill.
