Groo is a card game for two to six players (five is very good). It takes an hour or less to play.

In Groo, each player is the ruler of a town. You want your town to be the most glorious! Sometimes that means sending your troops to lay waste to neighboring towns, and of course, you need an army so they won’t lay waste to you. But the best-laid plans will go awry when Groo comes to visit, and your army will be of no use against the mighty barbarian . . . so you’ll have to do what you can to direct him to the other towns.
