Actuated Marble Tile

My design is like a game. The player is trying the control the spin speed of the wheel and release the ball at their chosen location so that the ball can roll into a hole. The ball can either be placed on the circle board and let it roll on its own or be placed on the path itself with some speed given to it. One thing I want to improve on is the range the wheel can grab as sometimes the ball would be stuck in the path because the wheel cannot reach it.
