Authors - One of the earliest versions of the family of Go Fish games, in which players call on each other to give up a named card, attempting to meld sets for points, based on which set of the game it is (e.g. the first melded set gets 10 points, the second gets 5 points). When all sets have been melded, most points wins.

This is Go Fish without the stock pile. All the cards are dealt out as equally as possible to the players. A turn consists of asking a player for a rank (or a specific card if you play that version). If they have it your turn continues; if not the turn passes to the player you asked. As in Go Fish, you must have a card of the rank you asked for. Books of 4 cards are discarded. The game continues until all the cards are formed into books, and whoever gets most books wins - or you can score one point per book and play to a target score.
