A simple Booby-Trap variant with magnetic sticks. Every stick is magnetic at only one end. You may continue to try to get one of the sticks as long as you can pull a stick out of the heap. You lose your turn either by choosing an nonmagnetic end of a stick or being by having chosen a stick which is too heavy for the magnet to pull out. At the end of the game every stick you got counts points according to its color. - BoardGameGeek
