You want the tower to be in order ( lowest numbers on the top getting bigger as you go down) They don't have to be in exact order, they just have to be largest numbers on bottom and small on top. For Ex:
YOu could have 1-3-5-7-11-20-25-34-35-50, 1 being on top and 50 being on bottom. Numbers you place in correct order give you extra points.
