Originally, Mind Quiz has been a handheld unit exclusive use launched by Segatoys in Japan. It became 200,000-unit hit hardware in Japan. The editorial supervisor is Dr. Ryuta Kawashima, whose books sold over 2 million copies in Japan as well. The PSP game introduces exercises of brain rejuvenating program at
a school utilizing blackboard. Questions are based on his books, considering the characteristics of PSP's 4 buttons.
The game's DS version Mind Quiz: Your Brain Coach, known as Nounenrei: Nou Stress Kei Atama Scan in Japan, is very similar to Nintendo's Brain Age: Train Your Brain in Minutes a Day! It involves playing 16 different training exercises to measure and improve particular parts of your brain, such as your Brain's Age and its Brain Stress Degree.
On 29/6/2007, Ubisoft, the game's publisher voluntarily pulled the game's DS version from store shelves in the UK upon complaints that the word spastic, a term that is considered offensive in the UK, was triggered when the player didn't perform well on certain questions. Ubisoft stated "As soon as we were made aware of the issue we stopped distribution of the product and are now working with retailers to pull the game off the market." (Wikipedia)
Gameplay Hints
Unlimited Brain Age Test for a day: Normally you can take only one Brain Age Test per day. The results are saved into your profile. However if the result (the brain age) is not good, then any other brain age test results will not be saved to the record until the next day. Use the following trick to redo the test for that day and get a better result without waiting for the next day. After the test, do not save the records' results. Press Home to quit and reload the game. You can now take the test again (with different questions) for the same day. Repeat this method until you get a good result.
Here's a rather poor demonstration of how the game works (poor footage that is, not performance on screen), as this is the only gameplay footage available for the PSP version:
