Abstract
A magnetic game wherein the playing field between a light-transmitting top wall and a bottom wall which is parallel to the top wall receives one or more playing pieces including one or more permanent magnets. The playing piece(s) can be attracted or repelled by an impeller having at least one shifting member with a permanent magnet adjacent to the upper side of the top wall. The shifting member is movable by a handle which is provided thereon or by manipulating an elongated arm a light-transmitting portion of which overlies the top wall. The impeller can be assembled of two or three shifting members, one above the top wall, another below the bottom wall or between the top and bottom walls, and a third between the top and bottom walls or below the bottom wall. Such shifting members can define a pocket which can receive a portion of or the entire playing piece when the distance between the magnet of such playing piece and the magnet or magnets of the impeller is reduced below a critical value.
