Pipoca

Pipoca is a two-player game that doesn’t require a table or much space — you can play it standing up, leaning against a wall, or even while waiting in line at the movies. It’s perfect for passing the time while waiting with someone. It’s 18-card game micro climbing game where the goal is to get rid of all your cards. You can play melds and upgrade your cards whenever your opponent beats them. Previously discarded cards return to your hand when you pass. The first player to go out wins the round, and the overall winner is the first to win two out of three rounds! —description from the designer
