This article describes a lab activity conducted in an introductory manufacturing class. In this good, simple, mass-production project, the students designed and produced a small game composed of a piece of plywood and 14 glass marbles. In appearance, the game is something like Chinese checkers, but it involves jumping over marbles, then removing the jumped marbles. The actual moves are similar to those found in an American checkers game. Directions, procedures and manufacturing details of the project, as well as instructions on how to play the game are presented. (Contains 3 figures.)
