HAHA "hacked" not likely. nah its just a trick, on the very last level of the bowling training, just go all the way to the right and angle it a LITTLE to the right, then release the b button later than usual with a LITTLE spin the to right. then when you release at the right time the ball will land on the side railing and with that little bit of spin it will spin back to the center. its cool i've done it before.
Yeah it works ive practiced a lot to get it right. Its how I got gold on that. But you have to get it ALL the way it cant fall down without hitting pins it has to fall down without hitting floor.
There are little red buttons you have to hit with the ball for the explosion to drop the pins. You can see the red buttons during the practice session, when the ball is close to the pins. It might work on the left hand side, too, but I've never tried it on that side.
