In Ubongo: Das Kartenspiel, players must once again figure out how to fit together the Ubongo pieces with which designer Grzegorz Rejchtman confronts them. Each round, a player receives nine cards at random from the appropriate deck for that round; each card shows six Ubongo pieces, with the pieces laid out in a 2x3 grid. Everyone simultaneously tries to "connect" seven of their nine cards. Two cards are connected when they lay adjacent to one another with a pair of symbols on one card touching a matching pair of symbols on the adjacent card. The first person to lay down seven cards in that manner shouts "Ubongo" and earns 10 points, while everybody else scores as many points as they have connected cards on the table. (If any player has made a mistake while placing cards, including the player who ended the round, that player scores zero points for the round.) For the second round, players flip over their nine cards and use them. For rounds 3-6, players receive cards from two new decks. After six rounds, the player with the highest score wins.
