Sphere50 is a child's toy based on luck, which looks simple but has a deceptive characteristic.
Children roll the ball back and forth and hope for the sphere to land on one of the flat surfaces. The surfaces range from small to large and each have a point system:Large Octagon - 5 PointsMedium Octagon - 10 PointsSmall Octagon - 25 Points
The trickery is in that the bottom of the ball is heavier and may not allow the ball to stop on the flat surfaces.
