Brain Age: Concentration Training

Dr Kawashima's Brain Training for Nintendo Switch

A new Brain Age title for the Nintendo Switch, titled Nō o Kitaeru Otona no Nintendo Switch Training (脳を鍛える大人のNintendo Switchトレーニング, lit. Nintendo Switch Brain Training for Adults), and as Dr Kawashima's Brain Training for Nintendo Switch for Europe and Australia, was released in Japan on December 27, 2019, and was released in Europe and Australia on January 3, 2020. The game uses some of the new features of the Switch, including the gyroscope and infrared camera in the Joy-Con units, as part of the input into the activities, alongside other returning training activities. A Switch-compatible stylus was also released that day in Japan to support some of those activities.^[1][2][3]

Sudoku

The North American, European and Korean versions of the first two Brain Age titles featured a Sudoku mode. The player can choose between two modes of play – with notification, or without. When played with notification, the game allows the player to miss only five times before the puzzle is automatically ended before completion. Each miss results in a 20-minute penalty which is added to the player's time. Additionally, if the best time for a puzzle was achieved with notification, the game will make note of that next to the best time.

The majority of the puzzle takes place on the touch screen, which displays the entire Sudoku puzzle. The player must first tap on the square he wishes to fill in, and the touch screen will show a zoomed-in image of that square while the other screen shows a zoomed out version of the puzzle. While zoomed in, you are able to move to another square next to it by using one of the arrows. To fill in a square, the player must handwrite the number using the stylus. Once the number is written and the player moves on from that square, it will be converted into a cleaner version of the number.

Brain Age also takes advantage of a strategy used in pen and paper Sudoku puzzles, in which the person marks which squares a number could possibly be by writing a miniature number. There are also four options at the player's disposal – Undo, Erase, Zoom Out, and Save & Quit. Undo allows the player to revert the latest change in the puzzle, Erase allows the player to erase everything in one square (alternatively, the player can circle just one number to erase it), Zoom Out is used to go back to a zoomed-out view after the player has zoomed in on a square, and Save & Quit allows the player to do a quick save and quit the puzzle, which is erased once the player resumes.

A DSiWare version of this game entitled Brain Age Express: Sudoku was released in the PAL regions on July 24, 2009, and in North America on August 17, 2009.,^[4] but it was retired from the DSi Shop on June 19, 2015.
