Manipulate the two balls into the center passageway (one ball on each
side of arch)
This classic dexterity puzzle is a well made cardboard box with a clear
plastic window on top. The quotation above is printed on the lid - shown in the picture
nested upside-down under the puzzle.
“A mechanical puzzle is a self-contained object, composed
of one or more parts, which involves a problem for one person to solve by manipulation
using logic, reasoning, insight, luck, and/or dexterity.” - Jerry Slocum
