The Wizard of Oz: Beyond the Yellow Brick Road is a DS game controlled entirely with the stylus on a trackball on the bottom screen. Using the track ball allows the player to move Dorothy around the 3D world of Oz. Coming in contact with enemies on the screen as they appear triggers battles with them. The game is a traditional RPG along the lines of the Dragon Quest games, where turn-based battles are fought in a first-person view. The playable characters' abilities are based on their personalities and actions from the original story. As an example, the Cowardly Lion has the ability to allow the party to escape from battles.
In Japan, the game is known as RIZ-ZOAWD, an anagram of WIZARD-OZ.
