Push notifications are one of the greatest retention drivers in free to play mobile games.
Especially on iOS devices there’s a strict rule that users should give permission to these push notifications. Otherwise users can’t get the push notifications that are sent by the game. And what’s super important about it is that you can ask for “push notification” permissions only once. So asking for permissions at the right time and place is crucially important.
Below are some examples in terms of how you can implement push notification permissions in your game.
