Roblox first-session diagnosis: from loss shape to repair

Repair the exit mechanism rather than the nearest red number. The curve shows when players leave, the funnel shows at which decision, observation shows what they encounter, and D1 shows whether they later return.

Original conceptual diagram. Not a product interface or measured results.

Four evidence types

Run an unguided playtest on a target device and record pauses, mistaken expectations, and errors. First-session retention locates early exit timing. Funnel completion locates the transition. Errors and performance explain technical mechanisms. No source replaces the others.

D1 and D7 need mature cohorts. Compare matching weekdays, sources, and supported segments; a blended average can move because mix changed. Before a causal experiment, before/after remains observational.

Loss	Possible cause	Check
Immediately after join	Loading, spawn, controls	Device test, errors, JoinReady
Before first action	Unclear goal or UI	Playtest and ActionStart
Action before reward	Difficulty, bug, delay	ActionComplete and server logs
After reward	No next goal	RewardUsed, repeat loop, feedback

One repair cycle

Suppose mobile players receive a pickaxe but do not swing. Observation finds a starter offer covering controls, while the ad promises a cave that spawn does not reveal. The team removes the obstruction and moves spawn. Both respond to observed blockers but remain separate log entries.

First verify completion and errors, then wait for the matching D1 cohort. If Paid remains weak after the first loop, the next question concerns the ad promise rather than a generic reward.
