Nintendo announced an American localization of the latest Brain Training game, known as Onitore, on Twitter this afternoon – complete with release date. "Dr. Kawashima is back to train your brain! Brain Age: Concentration Training launches for Nintendo #3DS on 12/3," the publisher said.

This game purportedly helps to increase the capacity of your "working memory," by subjecting you to mental gymnastics like answering math problems on a delay – as in you have to wait until you see the next problem to write the solution to the last one.
