Okay guys and gals, this one is MASSIVE! Our Rotation Pool set includes 2 though 9 ball rotation patterns meant to be played with a friend and has its own scoring system. Each set of patterns includes 30 layouts!!! That is 9*30 = 270 different patterns! Each set of 30 layouts are broken down into courses A,B and C that range and increase in difficulty. This game alone is worth what the whole system costs and we give it to you for no extra charge!
