It is kind of misleading beause the page assumes that you finished each difficulty in numerical order. What it really means is once you finish each stage on a specific difficulty you get an extra stone. An example is if you finish each stage on Z-Hard except for level 4, you will get 2 stones once you complete level 4 on Z-Hard instead of one.
