Sensory games

A method for detecting capture or replacement of a playing piece on a defined position of a game board comprising:

• providing a game comprising a game board on which there are a number of defined positions wherein each of said defined board positions is associated with an isotropic magnetic field sensor that has open and closed positions depending upon the presence or absence of a magnetic field, a first set of playing pieces and a second set of playing pieces wherein each playing piece is provided with a magnet having its N-S axis substantially upright and further wherein the pieces of a first set have the N pole facing downwardly and the pieces of a second set have the S pole facing downwardly, means for detecting the opening and closing of said sensors including momentary open and closed positions during capture or replacement of a piece of the first set by a piece of the second set or of a piece of the second set by a piece of the first set, and logic means for storing the positions of all playing pieces wherein the logic means is updated by the detecting means when the movement of a piece is detected by the opening or closing of said sensor;
• moving a playing piece from a first defined position to a second defined position on the game board;
• determining the movement of the playing piece with the detecting means;
• and
• storing the detected second defined position in the logic means.
