Nicely executed app, but flawed
Game is attractively done but it still deals duplicate cards to both players. This is a major flaw. Take screenshots of some of your end game screens when either player wins. You will often see as many as five or six pairs of duplicate cards. Gin Rummy, according to Hoyle, uses a standard deck of 52 cards when there are two players. This has not been fixed as of April 22, 2016. Older versions used to freeze up periodically. I have not seen freezing recently, so that may have been fixed.
