Abstract: The device utilizes a changeable-configuration geometric arrangement including a plurality of units, such as tetrahedrons, connected together at points by means of joints. The tetrahedrons can be equally divided into two different types of units that are exact mirror images of each other. The unit in each type has four triangular faces. The units along with the joints form an articulated chain in which any two adjacent units are of different types. The assembly of any two units connected together with a joint allows both units to rotate relative to each other in all directions around the center of the joint. In the articulated device, six consecutive units can be used to form the configuration of a cube. Different coloring and/or numbering schemes can be used to provide different levels of complexity and challenge for the puzzle. Units can be formed as right tetrahedrons having two faces with side lengths generally equal to (L, .sqroot.2 L, .sqroot.

The device encourages and permits a mental determination of the configuration of ropes within the chamber.

Abstract: An image transformation puzzle comprising a series of elements with image portions on respective front faces thereof successively linked together for incremental translational and rotational movement around a closed loop path between different positions in which image portions of different elements combine to form different composite images. Image portions of successive elements combine in one of the different positions to reduce the total number of composite images in that position producing a vanishing image effect. The elements may be formed as solid profiles of the image portions.

Abstract: A domino game is provided wherein some of the domino pieces have rotatable or convertible end sections that thus permit player a choice as the symbol to be displayed when the game piece is played. Symbols are displayed on both sides of each game piece, and the game pieces having rotatable or convertible ends can be changed to display alternative symbols, thereby adding to the challenge and complexity of the game. Preferably, the symbols comprise representations of U.S. or foreign currency or coins, with each game piece displaying both the front and back of at least one denomination. In one embodiment, the convertible game pieces comprise relatively rotatable sections. In an alternative embodiment, the game pieces have end sections that may be pivoted or flipped over, rather than rotated, to display different symbols. In another embodiment, each game piece comprises two separate sections which may be mated together in various orientations.

Abstract: The invention provides a puzzle embodied in a 3-sided regularly shaped pyramid comprising eleven smaller 3-sided pyramids and four small octaeder shaped bodies, which smaller pieces are connected to a string forming an endless chain. The complexity of the puzzle is achieved by coloring the side planes of the smaller parts in various colors and connecting the smaller pieces in a certain sequence to a string. The solution of the puzzle is obtained by placing the smaller parts of puzzle in such a way that the large pyramid is formed and the side planes of the large pyramid are uniformly colored by the smaller pieces. A preferred embodiment is given in FIGS. 1 and 2 comprising the 15 smaller pieces of FIGS. 3 and 4 placed in a continuous string as shown in FIG. 5.
