Taking back the principle of the arcade game Qix, or more recently of Pac-Xon, you will have to draw closed geometric shapes to cover more than 60% of the surface of the playing field and get to the next level. Collect bonus, appearing randomly, and avoid that the multiple enemies come in contact with your current trail under penalty of immediate death. Xonix 3D features 50 levels as well as the ability to save your score.
