Brain Age: Train Your Brain in Minutes a Day! (JP) (KO) (also known as Dr Kawashima's Brain Training: How Old is Your Brain? in PAL regions) is an educational program released for the Nintendo DS in 2005 in Japan and 2006 worldwide.

Based on the book "Train Your Brain" by the Japanese professor Ryuta Kawashima, it was part of the Touch Generations series by Nintendo. It was made to attract non-gamers into the gaming world. It has met major success in Japan, becoming one of the best-selling games that year, and it also did well in the US.


  • Brain Age Check - Try three different puzzles given at random and afterwards be given a brain age. 20 is the best brain age and 80 is the worst.
  • Sudoku - Over four hundred different Sudoku puzzles with four different difficulties including Easy, Normal, and Hard. To write in the numbers, you must write in the number on the touch screen. It is also possible to download Sudoku puzzles from a DS Download center.

  • Calculations x100 - Solve 100 simple math problems as fast as you can.

  • Stroop Test - This game uses the built in microphone in the DS or DS Lite. In this game, one of four words will come up (either Blue, Black, Yellow, or Red), each word will be in a font color other than the word (such as if the word is blue, the font won't be blue, but another color.), you must then say the color that the word is, other than the word.

  • President George W. Bush was given a Nintendo DS Lite and Brain Age for his 60th birthday.
