7 Claims. (Cl. 273-157) This invention relates to a crossword puzzle and more particularly to a three-dimensional crossword puzzle.
One of the objects of this invention is to provide a cross-word puzzle having a three-dimensional solution.
Another'object of this invention is to provide a threedimensional crossword puzzle made up'of blocks having characters thereon.
Yet another object of this invention is to provide a three-dimensional crossword puzzle made up of blocks wherein the faces of each block are designated in a specific order, so that the blocks may be arranged in layers according to designations to aid in the solution of the puzzle.
A still further object is to provide a three-dimensional crossword puzzle comprising, in its preferred form, 125 cubical blocks having a letter or mark designating a blank on eachface thereof and adapted to be arranged in an assemblage in the form of a cube consisting of five layers of blocks, each layer having 25 blocks arranged in the form of a square, each layer constituting an independent puzzle.
Another object of this invention is to provide a threedimensional crossword puzzle in the form of a cube composed of five layers of twenty-'five blocks arranged in a square, this cube being carried within a box so constructed that regardless of which of its sides the box rests upon, it may be separated without disturbing the cube of blocks, into two racks each comprising three sides of the box.
These and other objects and advantages will become more apparent from the following detailed description and accompanying drawing, wherein:
Fig; 1 isa perspective view of a set of cubical blocks assembled in a portion of the encasing box;
Fig. 2' is a plan view of all of the 125 blocks which constitute the puzzle, laid out in squares of 25 blocks each; and I Fig. 3 is a perspective view of the assembled blocks carried in one piece of the two piece box and showing the manner in which the layers may be removed with facility from the assemblage for further solution of the puzzle.
This three-dimensional crossword puzzle is in its preferred embodiment made up of 125 cubical blocks of equal size which are assembled in five square layers of 25' blocks each thus forming acube, each layer side constituting a separate crossword puzzle having an independent solution. On each face of every block is inscribed a character, either one of the letters of the alphabet, a numeral, or a mark designating a blank. In addition to the characters, the faces of every block are colored, the relative color positions being the same on each block. The assemblage or cube of 125 'blocks is encased in a box which is made up of two sections called racks, each constituting three sides of the box. Such a box makes it possible to expose any given portion of the-assemblage by removing one of the racks after manipu? lation of the box without disturbing the blocks.
The object of the game is to place each of the blocks in such a position that at one instant there is contained within the cube of 125 blocks solutions for thirty crossword puzzles. These thirty solutions are arrived at by completing thirty puzzles which are denoted by color and layer, there being five puzzles for each color and six colors.
As shown in Fig. l theassemblage or cube of blocks 10 is carried on a half box or rack 12. This rack comprises a bottom 14 with two side walls 16 and 18 extending vertically upward from two adjacent edges of the bottom. All of the sides of the side walls 16, 18 and the bottom 14 are approximately the same length so as to produce a cube when two racks are assembled. The top edge surfaces 20 and 22 of side walls 16 and 18 respectively are smooth while the free vertical end portion of side wall 16'has a vertical groove or channel 24 parallel to-its vertical edge. The free vertical edge portion of side wall 18 has a protrusion or tongue 26. Two of these racks 12 are combined to form a box for encasing and carrying the assemblage 10 and also for use in manipulating the layers of blocks when solving the puzzle. As will be readily apparent, the grooved edge of one rack 12 receives the tongue portion of the other rack while one bottom member 14 will rest on the smooth or flush top surfaces of the side wall members. The bottoms of the racks are made of relatively thin metal because there is a need for this as will be later explained. The side walls may be of wood of a suitable thickness.
Each face of each block 30 isinscribed with a letter of the alphabet or a mark designating a blank. The six faces of each block are colored, for example, black, red, blue, green, orange, and brown, the relative color .positions being the same on each block. The edges of each block are beveled, rounded or otherwise broken as indicated in Figures 1 and 3.
As shown in Fig. 3, the bottoms 14 or 14A of the racks 12 are used as slicer members. By this it is meant that the bottom 14A may be slid in between adjacent layers of blocks so that the layers may be removed from the assemblage and placed on a smooth. surface as indicated in Fig.2 for the solution of the independent puzzles.
Since the 125 blocks are formed in a cube which is live square layers of 25 blocks, each, it is obvious that there are 30 independent puzzles to be solved. The. puzzles color designations.
1 upper exposed faces of the blocks are of the same color,
preferably the black, for starting. With the black surfaces exposed on top, the blue surfaces should face the solver, the green faces would be to his right, the red faces to his left, the brown faces on the bottom, and the orange faces to the rear, see Fig. 1. The sequence in which the various color layers are solved' is of no consequence. However, the layers must be solved in accordance with the puzzle number, i.e., Black-layer 1, Blacklayer 2, etc. In assembling the layers to form an assemblage they must be placed one on the other in order of the layer number.
In replacing the layersof blocks on the rack it is sometimes difiicult to remove the slicer without disturbing the blocks positioned beneath the slicer and possibly those resting on the slicer. In order to obviate this difliculty, there is provided an angular holder 40. As shown in Fig. 3 this holder comprises two walls 42-42 connected at right angles to each other with a gripping tab 44 extending upwardly from one end of the intersection of the two walls 4242. In use, the holder is held by the tab 44 and the two walls placed against the exposed vertical faces of the blocks in a layer and the slicer then gently slid out from under the blocks.
With the 125 blocks on a surface and the black faces up, start to solve by working out puzzle denoted Black Layer 5, the fifth layer always being racked up first to form the bottom of the assemblage. In solving the puzzle, merely select the letters and dots (blanks) that when properly arranged produce what appears to be an answer to the proper puzzle definitions. After Layer 5 is finished proceed With the solution of Black-layer 4, then Black-layer 3, etc., until all of the Black-layer puzzles have been solved as shown in Fig. 2 of the drawing. After this the layers are stacked on the rack bottom 14 with the bottom layer being #5 and upward in order to #1. If the puzzles cannot be solved, place the extra blocks, oriented properly with respect to face color, into the places left unfilled and stack as indicated previously.
After this, place the second rack member over the assemblage to form the box, turn the box 90 in any direction and remove the rack member which is free, thus exposing a layer having a new color facing upward. As previously described, the layers are removed from the assemblage by sliding the rack bottom between adjacent layers, removing the layer and placing it on a smooth surface. This is continued until all of the layers have been removed and arranged as shown in Fig. 2. Remember that the top layer is always layer #1 as this will aid in preventing confusion in achieving the master solution. After removing the layers and placing them on the smooth surface, spread the blocks apart enough to be able to read all but the bottom faces. Next start solving the puzzle denoted by the color exposed and layer #5.
If the solver decides that the first letter in the first row is S and there is some other letter in that position, then he may take a letter S from anywhere in the layers of the same color. If there are a number of S letters in such layers the solver must decide which spot can use the other letters contained on the block which is to be replaced by the S. This procedure is continued until the five puzzles are completed and stacked on the rack as previously described. The other layers are solved in the same manner. Always remember, when shifting and interchanging blocks, to replace in kind the letters of the colors already solved if these letters appear to be correct. In addition, the solver may return and recheck color layers previously solved if he feels that such is desirable in view of developments encountered in solving subsequent puzzles.
When all of the puzzles have been solved then the master solution has been obtained and may be checked against the solutions given.
It will be obvious that upon the solution of two or three of the color layers the remainder will automatically be solved. This may be obviated by employing a few blocks which have more than three of their colored surfaces bearing the same letter on their respective faces. This wouldmean that the solver would not be likely to have a complete solution until he had solved more than the number of colored layers having blocks with the same letters on their respective faces. This theory may be developed to the degree desired to achieve the proper level of complexity.
. This puzzle has been shown and described using cubical blocks to form a cubical assemblage of blocks, obviously other block shapes may be used. The final assemblage of blocks may be of any shape desired as long as the layers are separable by means of a slicer member, otherwise it would be a tedious task to remove all of the blocks from the layers one by one.
Instead of coloring the faces of the blocks any suitable means may be used to designate the specific faces and their relationship to each other.
Although only one embodiment of this invention has been shown and described, it is to be understood that no limitations are intended other than those imposed by the scope of the appended claims.
