Cookie Cats A/B Test — First-Gate Placement
Decides whether a mobile game's first progression gate should move from level 30 to level 40, using decision rules set before the data was examined. 7-day retention was 0.8 percentage points lower at level 40 (95% interval 0.3 to 1.3 points lower), so the gate stays at level 30. The result held under a bootstrap interval and three sensitivity checks, with the limits of a causal reading stated alongside it.
