Puzzle Quest: Challenge of the Warlords review at Gamespot.

"For as often as developers attempt to marry distinct game genres hoping for a peanut-butter-and-chocolate-like result, they usually come out more peanut-butter-and-onion. Infinite Interactive's Puzzle Quest is one of the rare exceptions, and the way in which it integrates familiar puzzle gameplay into a traditional Japanese RPG format makes for an experience that is far greater than the sum of its parts. The way these disparate elements play off each other helps make it an incredibly difficult game to put down, and it finds a smart balance between accessibility, challenge, and variety that makes it an easy game to recommend to just about anyone."
