Cheating for a game like Brain Age is quite pointless, but it is possible and simple. If there is a question that may take you a few seconds to answer, close the DS, think it over, open the DS and write the answer.
After you get a stamp for the day, turn off the power and go to DS Settings and change the date to a day ahead. Go back to the game and you can get another stamp! This can be done for an unlimited number of times a day!
