To make a long story short, my wife is from the Ukraine. She was adopted at seven and started school late, she struggles at math and reading. She wanted me to find some decent puzzle or educational games for her. I know about Brain Age and stuff for the DS but I can't afford one just now. Are there any good ones for classic systems? Is Mario Is Missing, DK math and Math Blaster and such any good? If not recommend some more.

Thanks in advance.
