PQ2: Practical Intelligence Quotient 2 (also known as PQ2; in Japan; Practical IQ in Europe) is a puzzle game for the PlayStation Portable, and a sequel to PQ: Practical Intelligence Quotient. The game is based on testing the model of human intelligence developed by Dr. Masuo Koyasu at Kyoto University.

The player's score is based on the number of "moves" (excluding walking around) on the stage, the time it took to complete it, and
