Art Academy: Lessons for Everyone and Crosswords Plus both launch today on 3DS and both will be available in stores. However, Nintendo is offering a pretty nice deal for anyone who decides to go the digital route. If you purchase one of these games (or others) through the eShop you will also get a Donkey Kong game you can't find anywhere else, for free!
First things first, you'll need to be registered with Club Nintendo, so before you buy anything be sure to head over there. Once that's all squared away, and you purchase one of the specific games from eShop and register it with your Club Nintendo account, you'll be given a code for Donkey Kong: Original Edition -- a rare version of the NES classic featuring the Cement Factory level.
If you're not interested in picking up the new Art Academy game or Crosswords Plus, you'll be happy to know there are a few other games eligible to receive the free Donkey Kong classic. Style Savvy: Trendsetters, Paper Mario: Sticker Star and Professor Layton and the Miracle Mask will all land you the free game.
In order to secure your free eShop copy of Donkey Kong: Original Edition you'll need to purchase one of the eligible games and register it with your Club Nintendo account before Jan. 6, 2012. Head over here for all the details.
