Brain Age 2: More Training in Minutes a Day!

Brain Age 2: More Training in Minutes a Day!, known as More Brain Training from Dr Kawashima: How Old Is Your Brain? in PAL regions, is an edutainment puzzle game and the sequel to Brain Age: Train Your Brain in Minutes a Day!. It was developed and published by Nintendo for the Nintendo DS handheld game console. Before the game begins, the player must perform a Brain Age Check to determine their brain age, which ranges from 20 to 80, to determine approximately their brain's responsiveness. A brain age of 20, the lowest age that the player can achieve, indicates that the player's brain is as responsive as that of an average 20-year-old. After the player is told their initial brain age, they can complete a series of minigames to help improve their brain's responsiveness, after which they can run Brain Age Check again to determine their updated brain age.
Critics were generally favorable towards Brain Age 2, which received aggregated scores of 77% from Metacritic and 79.04% from GameRankings. Praise focused on improvements made on Brain Age, while criticism targeted the game's inability to consistently understand written and spoken answers. The game was voted IGNs Reader's Game of the Month for August 2007.

Gameplay

Similar to its predecessor, Brain Age 2 is an edutainment video game that offers the player several minigames to play. Before the game begins, the player must create a profile, after which Brain Age Check runs three random tests to determine the player's brain age, which ranges from 20 to 80 and depends on the player's test performance. The brain age determines approximately the responsiveness of the player's brain; a brain age of 20, the lowest age that the player can achieve, indicates that the player's brain is as responsive as that of an average 20-year-old. Once the player is told their initial brain age, three modes are unlocked: Quick Play, Daily Training, and Sudoku. In Quick Play, the player can practice with any of the available minigames without receiving a score. In Daily Training, the player can perform Brain Age Check to determine their updated brain age. They can also complete one of the available minigames, after which they are given a rating based on their performance. To let the player track their progress, the game saves daily statistics of the player's performance, which are shown in a graph. In the third mode, Sudoku, the player can solve one of a hundred Sudoku puzzles.
All of the minigames in Brain Age 2 are different from those of the original Brain Age. Brain Age 2 contains six minigames in Brain Age Check:

Rock, Paper, Scissors - Similar to the Stroop Test from the original, this minigame is played if the player answers "I can speak" when Professor Kawashima asks them if they can speak into the microphone. The player is given one of three hand shapes and an instruction to say the hand that will either win or lose against this hand.
Serial Subtraction - The player is given a starting number and must repeatedly subtract this number by the given number until it reaches the point where another subtraction would result in a negative number. The player must also memorize the last number as for every new number, it is quickly scribbled over.
Symbol Match - The player is given a list of ten numbers from 0-9 along with a random symbol corresponding to each number. A number to the right of the list is shown, and the player must write the matching symbol.
Math Recall - The player is shown a number, which is quickly scribbled as soon as the next number is shown. The aim is to add up the two numbers by writing the sum on the touch screen. When the player begins to write their answer, the second number is scribbled out as well. After each correct answer, one of the two numbers will be replaced with a different number.
Number Memory - The player must memorize a grid of 25 numbers in two minutes. After the time is up, the player must select a square in the grid and write the number they saw in that place.
High Number - The player is given several numbers, each displayed in different sizes. The aim is to touch the highest number.

The game's Training mode includes the following activities:

Sign Finder - The player is given a series of math equations with an operator missing. The aim is to write the correct operator that makes the equation correct.
Piano Player - The player is given a song to play on the piano and uses the touch screen to hit the keys as the music sheet progresses. There is also a Hard mode that hides the letters below the notes. The score is based on the accuracy of the player.
Word Scramble - The player is presented several rotating letters and must spell out a word using all of those letters.
Memory Sprint - The player must pay attention to the position of the dark racer as its runs in a race against the light racers. After the race is completed, the player writes the position that the dark racer finished in.
Change Maker - The player is given the cost amount and the bills and coins to cover this amount. The aim is to give the correct amount of change by subtracting the purchase cost from the total amount of the bills and coins offered.
Word Blend - The player must hear a word being said by a person and must recall what was said by writing the word. As the player progresses, more people are added, and the player must hear the words being said simultaneously. The player can skip a round if they are unable to write the words after five listens. Hard mode is also available.
Calendar Count - The player is presented with a calendar problem and must write the correct day of the week or date.
Math Recall - Same as the Brain Age Check version
Clock Spin - The player is given an analog clock with only the number 12 visible that is rotated or inverted. The aim is to write the correct time as shown on the clock.
Block Count - The player must memorize the blocks as they fall into the bucket. After all the blocks are placed in the bucket, the player must write the correct height of a given column.
Virus Buster - A simplified version of Dr. Mario modified for mobile play. This minigame is unlocked after the player receives a stamp on the current day. Note that the background music for Virus Buster alternates every day between the "Chill" and "Fever" themes.

During their training, the player can collect stamps by completing minigames, and only one stamp can be collected per day. When a certain numbers of stamps are collected, new minigames and features are unlocked.

Development

At a Nintendo press conference in Tokyo, Japan on October 5, 2005, the company announced several games that it would be releasing in 2006 in Japan. The list included Brain Age 2, with a release date set for December 29, 2005. Nintendo later announced that the game would be released in Europe on June 29, 2007, for €30, and in Australia on July 5, 2007, for A$49.95. The American version of Brain Age 2 was first revealed in May 2007. The game is targeted to casual gamers, similar to its predecessor; its basic concepts stay the same as in Brain Age, along with the graphics, menu, and presentation. Brain Age 2 also uses the same Sudoku engine, an addition in the original Brain Age that has been applauded for being one of the best handheld Sudoku games available; Brain Age 2s rendition of Sudoku introduces 100 new puzzles. All of the minigames in the game are new to the series; however, some of them are derived from exercises in Brain Age. One of the challenges in the first game, Head Count, requires that the player count how many people are shown on the screen; after a few seconds, a house falls on top of them, and then several people leave and enter the house. Afterward, the player must write down how many people they think are still in the house. A variation of this game is available in Brain Age 2, called Memory Sprint, which asks the player to observe a specific sprinter in a race as they pass other sprinters and are passed themselves, and then determine which place they finished in after they cross the finish line. The game's voice recognition technology has improved since the last game. The only challenge that uses the feature, Rock, Paper, Scissors, requires that the player speak the correct answer into the microphone as soon as possible.
Nintendo's advertising campaign for Brain Age 2 featured several celebrities. The company announced on June 25, 2007, that Australian actress Nicole Kidman would appear in European television and newspaper advertisements to promote the game. Nintendo chose to feature her because of "her universal appeal to mainstream audiences of all ages and backgrounds, as well as her reputation for being intelligent, entertaining and genuine". Kidman praised Nintendo's desire to reach out to new audiences with self-improvement products, and found that playing the game made her feel young. Nintendo also chose professional swimmer Kieren Perkins to promote Brain Age 2 in his native Australia, who commented, "Having used the original Dr Kawashima's Brain Training game for a while now, I was genuinely looking forward to all of the new ways I could exercise my mind. More Brain Training is the perfect way for me to continue my Brain Training workout, while keeping the activities fresh and interesting." In the United States, print advertisements and television commercials for the game featured American actress Liv Tyler.
