Brain Age 2: More Training in Minutes a Day

You can get extra Stamps, used to unlock things in the game, by turning the game on during different days. If you manipulate the DS' internal calendar, advancing it by a day and then turning the game on, you'll get a Stamp. Keep doing this over and over again until enough Stamps are earned that you have unlocked everything.

Keep in mind that when you set the calendar back to the normal day, earned Stamps from days that have not yet elapsed will be removed. Therefore, you must spend these Stamps before changing the calendar back to normal. While Stamps will be lost, things unlocked won't be.

Say the following phrases at the title screen to change the Doctor's expression:

Say 'Cilantro' and he will make a unhappy face. In the European version say 'Coriander'.
Say 'Pickled plum' and he will make a sour face.
Say 'Brain Age Two' to make his head swell. In the European version say 'More brain training'.
Say 'Doctor' to make him laugh.
