Thirty Day New User Retention report

The Thirty Day New User Retention report tracks the percentage of new user cohorts who return to the game on subsequent days. A Cohort of players is defined by grouping newly registered players on a given day (Day 0) and their retention is tracked over a 30-day period. Cohort size is determined by the number of players within it. The example report shown below, was generated on 2/5/2018. On 1/6/2018, 39,132 new players created accounts in the example title. Thirty-day New User Retention Report Table Since Day 0 is an initiation date for a new Cohort, this column always has 100% retention rate. Then 33.84% of those players logged in again the next day, 24.64% in two days later, and so on. 10.84% of the Cohort returned on the 30th day, which corresponds to 2/5/2018. For additional details, see Metrics and Terminology.
