Another entry in the burgeoning "brain building" genre, Best of Tests DS seeks to directly parallel IQ testing, to the point that developer Otaboo claims the game is "The best way to prepare for professional IQ tests." Players must use logic, memory, observation, and pattern recognition to get a high IQ score, and each test is different thanks to several hundred unique questions. Best of Tests calculates gamers' IQs and tailors every test to each player, with difficulty increasing incrementally as players get better scores.
