Abstract: A game is provided which requires the player to analyze and solve physical problems confronted while playing the game. The game may be played by all persons, regardless of age. The game features the construction of a track assembly which will enable a sphere to roll on the track assembly from the first end of the assembly to the second end of the assembly without falling off of the assembly. The track assembly is comprised of a pair of circular cylinders in parallel alignment and at least two braces positioned in the assembly to maintain the alignment of the cylinders. The sphere is caused, by gravity, to roll on top of the aligned cylinders from one end of the assembly to the other end without falling off of the assembly. There is also provided a method of designing the operative elements of the game (cylinder diameter, sphere diameter and cylinder separation) to change the level of skill required to play the game.
