In this game elves are rolling balls of different colors on the carpet. You have a Christmas tree and boxes of different colors. You need to catch the balls with your mouse and either hang them on the Christmas tree or put them into the box of the corresponding color. The balls that have hooks and a little Christmas tree sign must be hung on the tree. The other ones go to the boxes. You start with one elf and only tree balls. More elves and more boxes will add up as you progress.
