To do this glitch you have to go to the training mode at the bottom right of the main menu once your in training go to the bowling section and click on the middle picture called power throws. in this game you try to knock down as many pins as possible. once you get to the last throw you will see the blue railings on the side, go to the right side and make the throw go straight down the blue railing you have to make the ball go diagonal a little bit tap the right arrow about two ot three times when the ball goes perfectly straight down the blue railing all the pins will fall down. keep trying guys you'll get it
