A method of identifying ball movement, trajectory and position and a ball for use with a ball movement and position identification system are also disclosed.

Abstract: A puzzle toy that includes a plurality of push buttons that normally project from the surface of a cubic or spherical body. As the buttons are pushed in one at a time a latching mechanism residing within the body holds the buttons in a pushed-inwardly state, given a correct sequence of a subset of the buttons was pushed, deduced by logic and memory and including a chance mechanism. However if an incorrect sequence of the selected subset of button pushing is employed the user is unable to continue until all the buttons so far pushed are reset, either manually or automatically, forcing the player to start all over. The puzzle is solved when all buttons are pushed in flush with the body of the toy.
