Hi, i have a ( Ludo Champions Game ) on both android and iOS, i need to add some additional features to them. such as - OneSignal Push notification - The player should see his facebook friends who are already playing the game in the list and added automatically to his friends list ( already game has a sign with facebook ) - Make another list ( in this list will appear the friends who added manually ) - The player can challenge his offline friends, and the offline friend should receive a notification . ( NOW the online friends only can receive a notification ) - Invite friends and share game buttons, the player will get rewards about this.. - The Dice Will play automatically if the player lost the connection and can return to the room if it's connection came back - The player if he didn't press the dice after time-out , the dice and the pawn should play automatically , game will play in ( auto ) mode, until the player remove the ( auto mode ) manullay. - In the main menu ( login with facebook ) ( login as guees ) should add ( offline ) mode, the player will play against computer offline without need internet connection if it's not possible, make it to choose 1 or 4 players, and play with his friends who are sitting together ( in the same device ) My Game on google play [login to view URL] iOS [login to view URL]
