Make big groups of the same object in order to earn more bonus objects and to get a better score. This mini-game becomes harder in later rounds if you do not plan ahead. Use the blue or red bonus objects with the arrow shapes to destroy entire rows of wooden blocks. Plan your moves so that you can create groups of five or more objects. When you click on these bigger groups, make sure you select one of the objects in the group that is on the row you wish to clear. The bonus will appear on the object you selected.
