Drag light bulbs from the boxes below and place them on the Christmas tree. Click on the plug to try them out. A bulb that lights up is in the right spot. A bulb that flickers is the right color, but in the wrong spot. A bulb that does not light is the wrong color. Click the plug again to unplug the tree. You can then add, remove or rearrange the bulbs before trying again. You start with 1000 points and lose 1 point per second, and 50 points every time you plug the tree in.
