Phix: The Adventure is a 3D platformer in which Phix uses magnetic powers to attract and repel objects, defeat enemies, and overcome environmental challenges. Set across a series of colorful worlds, the game combines traditional platforming with physics-based puzzles and exploration as Phix attempts to return the Magnecia Stone to its sanctuary.

The Magnia Stone, the sacred stone of the Magnetic World is knocked off its floating altar in the sky and falls towards a slumbering creature called Phix. He swallows it and starts to attract metallic objects and creatures. This upsets the balance of the world, and evil creatures start to appear throughout the land. Phix must travel to five realms in order to bring the stone to its original place and return peace.
