Personal contact algorithm for VIP players

VIP managers used to contact players on a schedule — every 14 days, regardless of behaviour. I built an algorithm that knows each player's own rhythm: how long they usually pause between deposits and play. When a pause runs longer than their norm, the manager gets a task to reach out the same day. We tested it in an A/B test: +6% deposit days, and a touch on the signal day lifts return within 3 days by 11 pp. A second test is running in three regions.

Input

Each player's personal norm of breaks between deposits and play.

Model

A per-player threshold instead of a fixed 14-day schedule.

Action

When a player is silent longer than their norm, their VIP manager gets a task the same day.

Guards

A/B with ANCOVA, SPRT and intention-to-treat; a second test across three regions runs since October 2026.

Impact

+6% deposit days in the A/B test (p < 0.01); +11 pp return within 3 days when the manager reaches out on the signal day; in another region the same result with 12% fewer contacts.
