The goal of this classic marble puzzle is to be able to rest the marbles in the holes on each side of the block. Upon first contact with this puzzle, many observers will try to tilt the block to deposit the marbles in the holes. Quickly they will discover that the slope of each hole will not allow this to happen.
Commonly this puzzle has a divider in the middle to keep the marbles from touching. I found that I enjoy the sound that the marbles make when clacking together and the absence of this divider makes the puzzle more difficult.
