Schieblehre

There are five sliding tiles in this puzzle, three of which have slots. The slots can accommodate a small ball-bearing. The ball-bearing can also slide around in the large square gap. The objective is to slide the tiles and the ball-bearing around to navigate the ball from the 'Start' position to the finish in the upper-left corner of the puzzle.
