Formula and example
What counts as activity and which window to use
Activity can mean different things: a login, a real-money bet or a deposit. For revenue, the deposit matters most. The window depends on the task: D1 and D7 show the first days, D30 and beyond show the habit.
Pick one rule and do not change it. Otherwise retention will not match across reports and teams, and month-on-month comparisons lose their meaning. More in the article on active players.
Retention and churn
For one group and one window, retention and churn add up to 100%: if 30% were retained, 70% left. Overall retention across the whole base mixes new players with old ones, so decisions are made by cohort.
What drives retention
- The second deposit. Players who make a second deposit stay noticeably more often. Between the first and the second you need a planned journey, not silence.
- A fast first withdrawal. A stuck withdrawal often becomes the last visit.
- A reason to return without a bonus: levels, missions, tournaments, a daily reward.
- Personalisation: favourite games and providers in the lobby, emails and offers.
