Abstract: A manipulative game comprising a frame and a plurality of game elements, having planar sides matching in shape and size to planar sides of the frame. Each of the game elements includes a plurality of disconnectable means of attachment which, when connected permit a hinge-like rotation of a game element around the frames' rib. The game elements further include visual or tactile indicia on their planar surfaces, which in the assembled state, or otherwise in the initial state of order form a predefined pattern. In the initial state all game elements are connected to planar sides of the frame via means of attachment.

Abstract: A maze game comprising a plurality of movable maze pieces, a maze board, a housing, having a polygonal shape and containing said maze board, and a top, having slots, restricting maze pieces movements. The maze pieces of substantially elongated shape, arc located in the top's slots, extending both inside the housing, being received by the maze board's passages, and outside to be controlled by the maze handler. When moved in the direction allowed by the slot where it is contained, the maze piece either move along the passage of the maze board, or, if the direction of the slot doesn't coincide with the passage, move the maze board, if other maze pieces allow such a movement. The object of the maze is to place the maze pieces from one predetermined position to another.

Abstract: A logical puzzle including a plurality of elements stackable atop one another. Each element comprises pegs of varied lengths and apertures dimensioned to receive pegs therethrough. When all elements are properly stacked and oriented relative to one another, the apertures form passages permitting the reception of pegs, thus forming a substantially solid structure. By lifting elements and placing them in a random order a state of disorder is produced. The objective now is to restore the original state of order by stacking elements atop one another and by their suitable relative orientation in order to form a substantially solid structure. Although there are a multitude of incorrect ways to arrange puzzle elements only one correct arrangement allows them to form a substantially solid structure.
