Christmas Tree game is a small Christmas game where your challenge is to combine ornaments in the Christmas tree before the tree becomes full. Your goal is to gather Christmas gifts (received when combining ornaments). By combining ornaments of the same type and color, you get higher level ornaments or gifts, depending on the types of ornaments you are combining. On each level of the game, you should collect a specified number of Christmas gifts (or ornaments), in order to go to the next level.

There are three types of ornaments in the game: regular, decorated and sparkling. Two regular ornaments become one decorated ornament, two decorated ornaments become one sparkling ornament. Finally, two sparkling ornaments become one Christmas gift.
