Ker Plunk! is a classic game designed for 2 to 4 players. The setup involves arranging sticks in a lattice formation inside a translucent tube and placing marbles on top. Players select one of four compartments in the base and take turns carefully removing sticks while attempting to prevent marbles from falling. The objective is to finish the game with the fewest marbles in your compartment. The game retains its original mechanics while featuring a modern, updated design.
