CardSlugger app for iPhone and iPad
PSA CardSlugger is a multiple choice guessing game which challenges your knowledge of baseball cards in four different categories: Vintage HOFers and Stars, Vintage All Cards, Modern HOFers and Stars, Modern All Cards. Vintage games include cards which are dated pre-1970. Modern games are cards from 1970 to date. To keep things challenging, new cards will be continually added to the game as they become available.
