A new update to Wii Sports Club today adds the nine-hole Wii Sports Resort course to Golf. Also, the entire game, including all three currently released sports, is free next weekend.
The free trial, open to every Wii U owner, will be active as of March 21 at 9 a.m. PT and end at 11:59 p.m. PT on March 23. Currently, Wii Sports Club consists of Golf, Bowling, and Tennis, each with online play and Wii MotionPlus support. Baseball and Boxing are still coming at a later date.
The entire package can be played normally using a Day Pass, which grants access to all sports for $1.99 a day, and a Club Pass, which unlocks an entire sport permanently for $9.99 each.
