Your objective is to free a small metal ball from the maze through the exit hole. This is accomplished by maneuvering the wooden sliders around the fixed metal pegs until the opening is clear of obstruction. A very complex, methodical and intriguing puzzle!

The shaped tracks in the puzzle display like an "N" or a "5", hence the name of this series of puzzles that is available in different sized grids. This particular version of the series features a 10x10 grid of pegs and channels.
