Don't let the marbles DROP!
Put the cup-shaped funnel on the game base. Insert the sticks into the holes from one side to the other to form a net inside the cup. Pour all marbles into the cup.
Each player chooses his/her own tray and takes turn to remove the sticks one by one carefully. Try not to let the marbles drop. Game ends when all marbles drop. The one who has the least marbles win.
