So, don't know if you ever played Wii, care about Wii, or even know what a Wii is. However, as much as a used to love the power bowling training session, my love is now gone. I found this video of a trick used to basically cheat your way through the almight 91-pin set-up. It is very disappointing, but here it is, for your perusal.
Note- if you like Wii bowling, I suggest you take the upper-hand and not stoop to this horrible level of cheating.
