Even using five dice, you’re most likely to throw a number at or below eighteen, so three dice are enough. Your chances of throwing a number above eighteen are less likely, but if you choose to use more than three dice, throwing a larger number could happen. So in the interest of thoroughness, I have included the meanings for those numbers below.
