Skarney Kards contains a rule book and score pad for two card games and 30 variations written by the late, self-proclaimed 'World's Foremost Game Authority' John Scarne. Skarney Kards plays much like a simplified version of Canasta in which discards are passed around the table instead of forming a discard pile. Skarney Gin is much like Rummy except that, as in Skarney Kards, discards are taken back if no opponent accepts them. Skarney Gin also allows players to meld runs of mixed suits but an initial lay must consist of exactly 3 sets of 3 cards each. - BoardGameGeek
