Maze and Marbles

This is the classic mechanical maze and marble toy game brought up to the Christmas mobile gaming

There are concentric rings with a single entrance between each ring and the next. There is a set of twelve marbles

The objective is to tilt the device in different directions so as to roll a marble in the desired direction - the effects of gravity will roll the marble when the device is tilted. Continuous smooth manipulation is required to move the marble in the right direction. Please note that if the marble is touching the ring, the direction it rolls may not be what you expect due to its spin.

You will need to be deft and maneuver the marble at the right angle and speed to get it through circles and gather all of them at the center of the maze.
