Abstract

Abstract A flat, horizontal game board has a plurality of indicia displayed thereon. A plurality of discrete objects are positioned on the board. In one form of the invention, an elongated upwardly opening trough is supported in an inclined position on the board and being independent therefrom for movement to various positions thereon. A roller element, preferably in a hemispherical shape, has a flat circular side and gradually diminishing in diameter therefrom in a uniform manner. The trough has one elongated wall extending therealong in a vertical upright position and a second elongated wall extending longitudinally parallel to said one wall and extending laterally outwardly and upwardly to one side and from the bottom of said one wall. The roller is placed in the trough with its flat side flush along said vertical wall and with its diminishing diameter surface along the second wall and allowed to roll down the trough onto the game board.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 162 words
In a board game, a. a board providing a flat horizontal upper surface having indicia thereon defining various target areas, b. an elongated upwardly opening trough supported in inclined position on the surface and being independent of the board for movement to various positions thereon, c. a roller having a flat circular side and gradually diminishing in diameter therefrom in a uniform manner, d. said trough having one elongated wall extending therealong in vertical upright position and a second elongated wall extending longitudinally parallel to said one wall and extending laterally outwardly and upwardly to one side and from the bottom of said one wall whereby the roller may be rolled down the trough about the center axis of its flat side with said side moving flush along said one wall and with the roller portion having the gradually diminishing diameter rolling along the second wall until the roller departs from the lower end of the trough onto the board upper surface.
Claim 2
Dependent Claim 162 words
