Thelittle brother: Decisionmaker xs! If you don't feel to make a decision on your own you can consult this tool. It consists of the "rail cage", an "locking ball" and the "decisive ball". If the decisive ball drops in one of the tubes to the inner sphere, the locking ball - wich is trapped inside the inner sphere - blocks the direct way to the other side. So the decisive ball will seek another way out where it runs in one of the decision baskets. If the basket shows "Y" it means Yes and - guess the other letter!
