Beginning March 21 at 12 pm ET, Nintendo will offer Wii Sports Club Trial Access for Nintendo Wii U for free. That's the first time we've seen free access to these games. (For further comparison, these games would cost around $30 purchase.) It includes access to Wii Sports Golf, Wii Sports Tennis and Wii Sports Bowling games. Deal ends March 23.
