Pandemic (board game): Pandemic is a cooperative board game designed by Matt Leacock and published by Z-Man Games in 2007.  "Pandemic" is based on the premise that four diseases have broken out in the world, each threatening to wipe out a region.  The game accommodates 2 to 4 players, each playing one of five possible specialists: dispatcher, medic, scientist, researcher, or operations expert.  The game is unlike most board games in that the gameplay is cooperative, rather than competitive.  Through the combined effort of all the players, the goal is to discover all four cures before any of several game-losing conditions are reached.

Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus.  Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain.  One player must win; there are no draws.  The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem.  It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash.  The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production.  Hex can also be played with paper and pencil on hexagonally ruled graph paper.
