A system and method of providing a digital jigsaw puzzle game for mobile device is disclosed that comprises a computer physic simulation in which puzzle pieces are placed over a tilted surface displaying the picture of a puzzle. The tilted surface position and orientation within the 3D space of the simulation are driven by the motion sensors inputs of the mobile device. Each puzzle pieces are subject to gravity so that, as the user tilts the mobile device in a certain direction, the surface is tilted and the pieces slide down the surface in the corresponding direction. The motion of each puzzle pieces is computed using Newton's law of motion based on all external forces applied on each one. A puzzle piece moving close to its final position will be automatically placed and locked there. As a result of the above-mentioned, as the user moves the mobile device, he controls the motions of the pieces over the picture displayed on the mobile device screen in order to complete the puzzle.
