Method for playing a football-based bean bag tossing game

Cornhole games have been a mainstay during tailgating events at football games across the United States. However, the traditional cornhole game offers little challenge as the board has but one target opening and scoring is limited. Further, the traditional cornhole game has no real connection to the game of football; it does not present a representation of the field of play and does not apply the rules of football. The purpose of this invention is to create a method of play for a bean bag tossing game that is based on the game of football and incorporates the rules and strategies of the game of football. In an effort to create such a football-based bean bag tossing game, the game should incorporate the concepts of kickoffs, including onside kickoffs, punts, including fake punts, driving down the field by gaining yardage, the ability to kick a field goal or score a touchdown when in scoring position, the loss of yardage through application of penalties, the loss of possession through the application of turnovers, the possibility of scoring a touchdown after an opponent's turnover, the ability to attempt a last-chance Hail Mary touchdown, and the option to try for a 2-point conversion after a touchdown is scored. The game should also provide the player with an opportunity to use strategy when deciding what plays to make. With this football-based bean bag toss game, all of the main elements of the game of football listed above are incorporated and the game plays out similarly to a real game of football.
