Puzzle Quest: Challenge of the Warlords is a puzzle video game designed by Steve Fawkner for Australian game developer Infinite Interactive and published by D3 Publisher in 2007. The game combines role-playing with tile-matching elements. Taking place in a high fantasy setting, the player moves their character around the game's world and encounters monsters and other enemies to fight so as to gain experience and acquire treasure as in a typical role-playing game. Combat takes place on a board similar to Bejeweled, and by making matches of coloured gems, the combatants can cause damage to their opponents, cast spells, or perform other abilities that affect the flow of the game.

Puzzle video games make up a broad genre of video games that emphasize puzzle solving. The types of puzzles can test problem-solving skills, including logic, pattern recognition, sequence solving, spatial recognition, and word completion. Many puzzle games involve a real-time element and require quick thinking, such as Tetris (1985) and Lemmings (1991).
