Get paid for play and bring players back. Sell coins through the store, share scores as challenge links and ping players when it's their turn.

Notification permission

Ask players about challenge alerts once they have played a round, not on first launch.

  • Show what a challenge alert looks like before the prompt appears.
  • Ask once a player has won a round and a rematch is on offer.
  • Send declined players to notification settings from the game's options screen.
