Go Fish

Go Fish for two. Each player is dealt 5 cards; the rest form a face-down draw pile in the middle.

Ask your opponent for a rank you're holding — "any sevens?" If they have any cards of that rank, they hand all of them over — and you ask again. If they don't, go fish: draw one card from the draw pile (while it has cards left) and your turn ends. Collected all four cards of a rank? Lay them down as a book. Out of cards? Draw one from the pile to keep playing, or pass if the pile is empty.

Play continues until every card has been laid down in books. Whoever made the most books wins; an even split is a draw.
