when playing bowling move ur character all the way to the left or rigth then press A and then press left or right(if u moved to the left gutter hold in left on the d-pad if right then hold in right on the d-pad)then hold in B untill your character stands on one foot near the place where you throw the ball the pull ur arm back then forward really hard as going up let go of B as you normally would and itll go into someone elses lane time it right and youll collide with someone elses ball or try to do what i did give THEM a strike ;)
