The object: try not to lose your marbles. A long-time favorite, Ker-Plunk takes a steady hand, as you skillfully remove the sticks from the marble-filled tube. A clear plastic tube is filled with marbles, which are supported by crisscrossing sticks inserted through the tube. Each player takes a turn removing a stick from the tube, trying to dislodge as few marbles as possible. As the game progresses and fewer sticks remain, it gets harder to keep the marbles from going ker-plunk! Play continues until all the marbles have fallen. The player with the fewest marbles in his compartment wins! For two to four players.
