This app is a simple Gin card game that can be played by people with iPhones nearby each other.
When the app is loaded it displays other players nearby running the app. No need for an Internet connection - Bluetooth or WiFi is all that is needed. Players must be all connected to the dealer before proceeding.
When one player starts a game the app on their device controls the playing deck, the discard pile and whoss turn it is. Gin is achieved by a player arranging their cards in the correct order for Gin (3 or 4 of a kind and/or a straight of 3 o4 of the same suit).
If any player leaves the app other players will be notified. If the dealer leaves the game will be ended, otherwise the game can continue when all players are reconnected.
