Abstract: The invention is a device that modifies the target aperture for the standard game board for the traditional lawn game known as cornhole or bean bag toss. The device, when inserted into the game board's target aperture, replaces the open hole with a circular shaped “trapdoor” that opens only when directly struck by a tossed game bag. When opened, the trapdoor allows the passage of the game bag through the game boards target aperture. The device includes a spring hinge mechanism that returns the trapdoor to the closed position after the bag has passed through the opening. The device is designed so that it can be quickly and easily inserted into and removed from the target aperture of the game board without moving or damaging the game board.

Abstract: The invention is a game difficulty modifier for the traditional lawn game known as cornhole or bean bag toss which utilizes inserts to change the standard target aperture in the cornhole game board. The insert adapter changes the difficulty level of the game by either altering the size or nature of the game board's target aperture. The insert adapters are designed to be easily installed and removed from the game board allowing players to experience different levels of difficulty during the same game.
