Pipes

Pipes is a crazily intense two-player card game that is cunningly easy to lay out. You have 20 cards in the box, including the two starter cards that you lay out in a 4 by 4 grid. In 5 - 10 minutes, you need to use your pipes and steal your opponents' to connect your starting valve past them to win. Crush them fast because failure is just one mistake away. —description from the publisher
