Destroy all enemies (Word Attack - Space mode)	AYXB

Note: You only get to use this one time every time you train with this.

Any time after the initial Brain Age Check, if you obtain a Brain Age score of 20, you will unlock the Challenge Mode. NOTE: This is MUCH harder than what you normally do in Training.

Once a day, if you do a Training game or a Brain Age Check, you will get a stamp. Should you collect enough of these stamps, you will unlock new games, modes, and options. NOTE: To do Virus Buster after it's unlocked, you must have a stamp for that day.
