Work Derby is a game of worms racing through a changing maze of obstacles, around a distant pylon and back to the starting line. It is a game for James Kyle's piecepack system. A worm is a line of six piecepack coins, where movement is done by taking coins from one end of the worm and adding them back to the other end, similar to Alex Randolph's game Wurmeln. Movement and moving obstacles are control by die rolls.
