Bionicle: The Game (also known as Lego Bionicle and titled on the cover as simply Bionicle) is an action-adventure video game released in 2003. The game is based on parts of the movie Bionicle: Mask of Light and other parts of the Bionicle storyline. Initially, the game was supposed to make each Toa, Toa Nuva, and the Toa of Light playable, but due to deadlines, much of the game was dropped. However, all of the characters are playable in the Game Boy Advance version. The Mac OS X version of the game was released by Feral Interactive.

Playing as the Toa, Toa Nuva, and finally the 7th Toa, you must explore the six elementally-themed regions of Mata Nui - a tropical paradise of high mountains, great lakes, and mighty volcanoes - rescue the scattered Matoran and break the spell of darkness sent by the evil Makuta. In doing so you will face danger in equal measure from the islands many environmental hazards (including falling rocks, rainforest winds, icicles, and lava falls) and the foul minions of Makuta. Choose any one of the six Toa characters to begin your adventure. Use the unique elemental powers of the Toa and summon blasts of elemental energy to defeat your enemies.
