Tapping the Retention graph or text under it will reveal more detailed retention stats.
Retention measures the stickiness of your game by telling how many players return to play again after playing it for the first time. This key metric is affected by things such as the core game loop and first-time user experience.
Tapping the More button opens the How to Improve Retention for Your Game article.
Provides the total percentage of players who have returned to your game after the first session as well as percentages for players who return after days 1, 2, 3 & 7.
Keeping players coming back to our games is a big challenge for all creators, don't get discouraged if these numbers are very low but do see what you might do to improve them.
Getting these numbers to go up is great news for your game.
