In Cooperative games players work together to achieve the game’s objective. Instead of competing with one another, the group plays against the board.
Games like Pandemic, Forbidden Island and Forbidden Desert have players discuss and work out the best way possible for the group to stay alive!
Some cooperative games, like Castle Panic, have a device that allow one person to be the absolute winner.
I love cooperative games for family game night, or as a way to introduce new game players to strategy type games. Everyone has equal input, and new players can learn the game as they play.
