Tetris may have opened the way for portable puzzlers, but Puzzle Quest stands above the pack. Its unique combination of puzzle-solving and role-playing is like nothing else out there. Not only does it provide immense depth, but also makes the game incredibly addictive. +1 charisma for this PSP version thanks to a cleaner presentation, although the DS edition gets a special enchantment for intuitive touch controls. Anyway you put it, Puzzle Quest levels up handheld gaming as a must-own.
