The game's core gameplay is straightforward. Taking control of Harry, the player explores Hogwarts castle and grounds. Throughout the course of the game, the player will encounter events that tie into the storyline of the second book. Filling the gaps between these events are various classes, where the player will learn how to fly a broomstick and learn new spells for combating bosses, among other things. Each new spell is accompanied by a challenge, which the player must get through in a certain amount of time to complete that class period. During the later parts of the game, the player will face challenges which are not time-limited and are not related to learning spells. These challenges are all based on events from the book, for example, travelling into the Forbidden Forest and gathering ingredients for a potion Hermione is making.

The PlayStation version of the game is a sequel to the Harry Potter and the Philosopher's Stone game and was also developed by Argonaut Games. It retains many elements and graphics from its predecessor but with some places in Hogwarts being modified as well as new mini-games that are introduced as the storyline progresses. Most of the new spells learned from attending classes are upgrades from the previous game.

Developed by EA UK and Eurocom, the GameCube, PlayStation 2 and Xbox versions of the game allow the player to access a broom and enter free-flight mode. While the PlayStation 2 version allows the player to land anywhere they want, in the Xbox and GameCube version the landing zones are limited. In the GameCube version, there is an exclusive feature involving GC–GBA connectivity that allows a secret room to be opened when the two versions are connected.

The Microsoft Windows and Mac version of the game was developed by KnowWonder and Westlake Interactive. The game features the same graphics and character design as the Philosopher's Stone (PC). It retains some of the spells learned in the previous game and involves the player learning new spells by attending more classes at Hogwarts.

Developed by Griptonite Games, the Game Boy Color version is a role-playing game. Harry Potter, Ron Weasley, Hermione Granger and Gilderoy Lockhart are all playable characters at various points in the game.

Developed by Eurocom, the Game Boy Advance version has the fewest spells and is mostly made up of mini-quests.
