Brain Age: Concentration Training

There are 3 types of training modes: Devilish Training, Supplemental Training, and Brain Training. Unlike past installments, the 3DS is held in its standard position, rather than sideways (except for Relaxation Mode). The player utilizes the handheld's touchscreen and microphone to perform training and minigames.

In the training mode for the player's working memory, Devilish Training, the player is assigned with a training exercise for 5 minutes. In the exercises, the difficulty is adjusted to match the player's efforts. The difficulty level goes up if the player completes the routine with 85% or more correct, or if both questions are answered correctly. The difficulty level remains the same if the player receives between 84 and 66% correct, or if only one of the questions were answered correctly.

The game was planned to be released in Europe on March 8, 2013, and after to April 12, 2013; however, despite releasing fully localized information on the title, Nintendo of Europe had since announced the game's release being postponed on April 9, 2013.

On April 12, 2017, during a Nintendo Direct, Nintendo announced the release date for Europe. The game was released on July 28, 2017, exactly five years after the original Japanese release. Nintendo Australia later also confirmed a local release in Australia.

Some gaming journalists were initially antagonistic and skeptical towards Brain Age: Concentration Training. A Destructoid writer rebuked its price in the same paragraph he dismissed the entire series as a craze that has died. Destructoid did, however, comment on the game's willingness to improve any player's memory by an enormous amount. GameRadar+ AU dismissed the game in a way that contradicted Destructoid, quipping that "if you've read [this paragraph] description up until this point, you're likely ahead of the game," implying anyone literate is too intelligent to get much out of the experience.

IGN's Mr. Thomas insisted the premise of a "devil doctor" would make the game less appreciated by who he considers to be the target audience of "older, non-gamer adults."
