Cornhole a.k.a "tailgate toss," "bean bag toss," "baggo," "dbags," or "bags" is a lawn game in which players take turns pitching cornhole bags—cotton duck bags filled with feed corn—at a raised platform with a hole in the far end. These platforms are usually made with plywood or occasionally plastic, and are often decorated. A corn bag in the hole scores 3 points, while one on the platform scores 1 point. Play continues until a player reaches the score of 21.
