Abstract: A cartridge housing a cubist puzzle game having a set of polycube pieces and a deck of playing cards associated with the set. Each polycube piece is formed by at least three like cubes joined together in a common plane in various ways to define the geometry of the pieces. When these piecess are intermeshed in a common plane, they then form a rectangular pad. When otherwise interfitted, the polycube pieces then create multiplanar cubist figures whose configuration depend on how the pieces are interfitted.

The opposite face of the card displays this relationship and, therefore, a solution to the puzzle. The cartridge is provided with a rectangular frame divided into a first open compartment for accommodating the pad of pieces and an opposing second open compartment for accommodating the deck of cards.

Abstract: A puzzle game comprising a hexahedral semisold body (10) having a number of non through-holes (12) and a like number of round pegs (18) to be plugged into the said holes. The holes of the hexahedral body are made on three faces (11) sharing the same vertex (14). Each hole on any face intersects sideways sets of aligned holes of each of the remaining two perforated faces. The pegs are provided with pairs of round notches (20).

Abstract: A take apart wooden toy puzzle which, when assembled resembles a San Francisco cable car. The toy comprises a number of pieces, the majority of which comprise pairs of mirror image constructed pieces which align and are mutually interacting. Two key element pieces must be detected and removed from the puzzle in the correct order in order to disassemble the puzzle. The first set of these elements, the brake posts, must be removed. At this point, the cable car is able to roll upon its wheels without falling apart. Since this initial procedure leaves the toy intact, the next element to be removed is not easily ascertained. The next step consists of disengaging the second step of key elements, the tie posts, which are fitted top to bottom through the puzzle. Once the tie posts are removed, the toy is easily and quickly disassembled. When it is desired to assemble the toy, it is conducted in the reverse order of disassemblage. The pieces of the puzzle are held in place until the tie posts are inserted.
