Description

The present invention relates to a tool for logically deciphering Sudoku problems.
This tool consists of a 3-piece set of 8 mm grid paper (9-81-729 grid paper) consisting of 729 grids of 27 x 27 grids, an alignment number board, and an 81-grid perforated sheet. Since the numerical information is devised to maintain a consistent and regular arrangement order and arrangement position among the three-point sets, the ability to decode the numerical information like spectral analysis is provided. characterized by having

The outline of the procedure for capturing the Sudoku problem is as follows.
On 8 mm grid paper (9-81-729 grid paper) consisting of 729 grids of 27 × 27 grids, re-edit the Sudoku problem and create a question and record sheet.

On the board surface of the arrayed number board, the three types of numbers displayed/provided by an arbitrary blank for questions are blinded with three types of non-numeric blindfold cards corresponding to each.
The numbers that remain unblinded are the answer proposals for the blanks, so transcribe and record them on the above-mentioned question and recording form so as to maintain the original arrangement order and arrangement position.
Sequentially fill in the blanks and fill in all the blanks on the above-mentioned question and recording form with the proposed answers.

By applying an 81 grid perforated sheet to the question and recording form in which all the blanks are filled with the answer proposals, all numerical information, which is the answer proposal, will be converted to numbers from 1 to 9 (1 to 9). Separately, simultaneously, by block, by horizontal row, and by vertical column, it can be analyzed like spectrum analysis.
In combination with the elimination method, it is possible to logically decipher each blank into one answer.

Traditionally, arrayed number boards have not been equipped with three types of non-numeric blindfold cards that function for different purposes.

Also, there was no question and record sheet using grid paper composed of 729 grids of 27 × 27 grids in which 9 grids were assigned to each blank or 1 number column.

Furthermore, the question and recording paper using the grid paper composed of 729 grids of 27 × 27 grids was superimposed on the question and recording paper using the grid paper composed of 729 grids of 27 × 27 grids. Nor was it equipped with an 81-square perforated sheet that could sometimes be dimensionally coherent and interlocked.

It had the following drawbacks.
(b) In the past, arrayed number boards were not equipped with three types of non-number blindfold cards that functioned for different purposes.
Therefore, the multiple answer candidate numbers that should be obtained as answer proposals for any one of the blanks in the question are treated as answer proposals that maintain the regular arrangement order and arrangement position as they are in the original arrangement order and arrangement position. The method of use of providing/displaying so that it can be transcribed/recorded could not be established.

Focusing on any one blank of the question, the one blank is displayed as a target to be blindfolded ・The number group provided is
The number inside the corresponding block ,
Numbers in the horizontal row targeted for the corresponding block "outside" ,
and ,
There are three types of numbers in the vertical column of numbers that are targeted for the "outside" of the corresponding block.

When blindfolded with the 3 types of non-numerical blindfold cards that should have been equipped with each of the above 3 types of numbers, the group of numbers that remained unblinded are numbers as a draft answer. The scheme that it should constitute a group could not hold.

In other words, it is possible to transcribe and record the group of numbers that remain without blindfolding as an answer plan that maintains the regular arrangement order and arrangement position as it is in the original arrangement order and arrangement position. It can be said that the usage method of displaying and providing such information could not be established.

(b) Also, there was no question and record sheet using grid paper consisting of 729 grids of 27 × 27 grids with 9 grids assigned to each blank or 9 grids per number column.
Therefore, even if the numeric information, which is displayed/provided by the arrayed number board and is a draft answer to any one of the questions, is transcribed/recorded as it is, the numbers maintain a consistent and regular array order and array position. Information could not be recorded.

This means that even if the contents of the questions in the Mainichi Shimbun's "Asa kara Sudoku" yesterday and today's questions are different, the numerical information that maintains a consistent and regular arrangement order and arrangement position can be obtained. As such, it was far from the standardization of recording.

(C) Question and recording paper using grid paper composed of 729 grids of 27 × 27 grids is superimposed on question and recording paper using grid paper composed of 729 grids of 27 x 27 grids. Nor was it equipped with an 81-square perforated sheet that could sometimes be dimensionally coherent and interlocked.
Therefore, , which should have maintained the regular arrangement order and arrangement position, and the number information and its arrangement information which should have been recorded as they are,
"By number 1-9" and at the same time,
By block of 1-9 , and ,
For each horizontal line from 1st to 9th, and ,
By column from the first to the ninth vertical column ,
Since it was not possible to develop and classify the answers in an orderly manner, it was not expected that logically narrowing down the number of answer candidates and reducing the number could be easily realized.

(d) With the conventional trial-and-error method, it takes a considerable amount of time to lead to one number per corresponding entry field, and the deciphering act has to be abandoned halfway through due to fatigue. There were many.
Also, every time I challenged a high-level problem, I often experienced resignation and frustration.
The present invention has been made to eliminate the drawbacks as described above.

Aligned number board (1), 8 mm grid paper (9-81-729 grid paper) composed of 729 grid numbers of 27 × 27 grid (5) and 81-grid perforated sheet (9), each Describe the means to solve the problem.

(b) Aligned number board (1)
The arrayed number board has 12 shallow card holders (2) of the same specification mounted on the board (1) surface in an arrangement of 3 rows and 4 columns, of which 9 card holders are arranged in 3 rows and 3 columns. On the inside, a card (4) on which nine numbers 1-9 are written is attached and fixed so as not to come off so as to maintain the regular arrangement order and arrangement position. It is a number board (1) in which three types of non-number blindfold cards (3) are placed in three card slots arranged in three rows and one column so that they can be easily taken in and out.
The arrayed number board is a number board equipped with non-numerical blindfold cards having the structure described above.

(b) 8 mm grid paper consisting of 27 × 27 grids with 729 grid numbers (9-81-729 grid paper) (5)
8 mm grid paper (9-81-729 grid paper) (5) consisting of 27 × 27 grids with 729 grid numbers seems to be easy to obtain, but it is not easy, so it is handled by processing ready-made products. .

Use the KOKUYO Campus Notebook (8mm grid ruled) from KOKUYO.
One by one ・ ・ ・ Precisely cut.
Two rows of 8 mm width on the cut side of the two cut graph papers are used as glue margins. Glue them together so that they do not shift, and make a sheet of 8 mm grid paper.

And since one blank is composed of 9 grids of 3 × 3 grids, a ruled line is drawn for each of the 9 grids corresponding to one blank, which corresponds to 9 blanks per block. If you draw ruled lines to divide each block consisting of 81 squares of 9 × 9 grids, and draw ruled lines to form a total of 9 blocks and 81 blanks, you can find the known numbers of the Sudoku problem. 8 mm grid paper (9-81-729 grid paper) (5) composed of 729 grid numbers of 27 × 27 grids is ready to transcribe (numbers of questions).

(C) 81-grid perforated sheet (template) (9) 8-mm grid paper composed of 729 grids of 27 × 27 grids (9-81-729 grid paper) In (5), 1 blank Prepare 81 (6) center positions of each of the 81 blanks (intersection points of two diagonal lines of the blanks that are squares) when ruled lines are drawn for each of the 9 grids of the 3 x 3 grid assigned to Transfer it to a slightly darker transparent or translucent plastic sheet (7), and center the transferred position on 8 mm grid paper (729 grids of the 27 x 27 grid) 5) 81 holes (8) with a size corresponding to one grid are drilled accurately so as not to be misaligned.
Then, when ruled lines are drawn so as to form 9 blocks for the 81 holes (8) that have been opened, when superimposed on the 8 mm grid paper composed of 729 grids of the 27 × 27 grid, , a perforated sheet (template) (9) with 81 squares that can be closely and interlocked in dimension is completed.

The present invention provides an arrayed number board (1), 8 mm grid paper (9-81-729 grid paper) (5) composed of 729 grids of 27×27 grids, and 81 grids, as described above. The perforated sheet (template) (9) consists of three constituent elements, and the numerical information shared by the three constituent elements is designed to maintain a regular arrangement order and arrangement position. It is characterized by having a function that can decode the numerical information like spectrum analysis.
Therefore, by combining and using each function so that it interlocks with each other, it is possible to capture the Mainichi Shimbun 'Sudoku from the morning' problem.

(b) The arrayed number board is equipped with three types of non-numerical blindfold cards that function according to purpose, so you can use multiple answer candidate numbers that can be obtained as answers to any one of the blanks in the question as they are. We were able to establish a usage method of displaying and providing answers in the same arrangement order and arrangement position as it is, so that it can be transcribed and recorded as an answer plan that maintains a regular arrangement order and arrangement position. .

In other words, focusing on any one blank in the question, the blank is displayed as a blindfold target ・The number group provided is
The number inside the corresponding block ,
Numbers in the horizontal row targeted for the corresponding block "outside" ,
and ,
There are three types of numbers in the vertical column of numbers that are targeted for the "outside" of the corresponding block.
With each of the three types of numbers mentioned above, with the three types of non-numeric blindfold cards that the arrayed number board is equipped with, when the blindfold is executed within the board surface, the group of numbers that remain unblinded. can now be displayed/provided as a draft answer for that one blank.

In other words, by equipping three types of non-numerical blindfold cards, the arrayed number board displays the numbers remaining without the blindfold in their original arrangement order and arrangement position. , it is possible to display and provide as an answer plan that maintains the regular arrangement order and arrangement position, and if the displayed / provided number group is transcribed and recorded as it is on the question and recording sheet It can be said that it has become possible to establish a usage method that is good.

(b) Then, the questions and recording paper using grid paper consisting of 729 grids of 27 × 27 grids with 9 grids assigned to each blank or 1 number column is processed from ready-made products. can be ensured by doing so.
Therefore, it is possible to directly transcribe and record the numerical information, which is displayed and provided by the arrayed number board and which is an answer to any one of the blanks in the questions, and to achieve a consistent and regular arrangement order and arrangement position. can be recorded as numerical information that maintains

This means that even if the contents of the questions in the Mainichi Shimbun's "Asa kara Sudoku" yesterday and today's questions are different, the numerical information that maintains a consistent and regular arrangement order and arrangement position can be obtained. As such, it is possible to aim for standardization that can be recorded.

(C) Question and recording paper using grid paper composed of 729 grids of 27 × 27 grids is superimposed on question and recording paper using grid paper composed of 729 grids of 27 x 27 grids. It has become possible to newly devise and equip a perforated sheet with 81 squares that can be closely and interlocked dimensionally.

The positions of the holes in the perforated sheet with 81 grids are dimensionally closely and interlocked with the 8 mm grid paper (9-81-729 grid paper) composed of 729 grids of 27 × 27 grids. 8 mm grid paper composed of 729 grid numbers of 27 × 27 grid (9-81-729 grid paper) 81-729 graph paper) Even if there is a large amount of numerical information on the paper, if the order and position of arrangement are consistently maintained, the above 81 grid perforated sheet is used for searching. By (scanning) the numerous numerical information can be deciphered like spectrum analysis.

Therefore, the regular arrangement order and arrangement position are maintained, and the numeric information and its arrangement information recorded as they are,
"By number 1-9" and at the same time,
By block of 1-9 , and ,
For each horizontal line from 1st to 9th, and ,
By column from the first to the ninth vertical column ,
Since it can be developed and sorted in an orderly manner, it is possible to narrow down the number of answer candidates and reduce the number as a result of logical development, leading to one number per corresponding entry field.
In the reduction process, it is also possible to develop and utilize new elimination methods in addition to existing elimination methods.

Searching (scanning) with the aforementioned 81-grid perforated sheet means that the size corresponding to 1 grid is 8 mm, so the 81-grid perforated sheet is scanned 8 mm at a time (1 grid at a time). ) by shifting (scanning)
"81 holes"
Numbers of "1" and "blanks"
Starting from providing and displaying , sequentially ,
The number of "2" and "blank" ・The blank gathering situation is
The number of "3" and "blank" ・The gathering situation of blanks,
・ ・ ・ ・ ・
The number of "8" and "blank"
Since it is to provide and display the digits of '9' and 'blanks' and the gathering situation of the blanks, the digit information and its arrangement information are systematically analyzed 'by the numbers of 1-9' like spectrum analysis.・Be able to decipher.

(d) The arrayed number board is a 27 x 27 squared grid of 729 numbers, with the numerical information and arrangement information of all the numbers that can be the answer proposals kept as they are and accurately, while maintaining the regular arrangement order and arrangement position. Can be provided on 8mm grid paper (9-81-729 grid paper) consisting of grid numbers.
Let A be the number of pieces of numerical information at this point, including the known number of questions.

Then, the 81 grid perforated sheet was applied to the raw, numerical and placement information on the provided or collected 8 mm grid (9-81-729 grid) paper. As a result, the analysis and subtrahend processing can be developed orderly and logically. Let B be the number of pieces of numerical information at this point, including the known number of questions.
As a result of such logical development, the answers to the questions can be obtained. The number of pieces of numerical information at this point, including the known number of questions, is B=81.

In some cases, you may not be able to get the answers to the difficult questions in the advanced class (hermit edition).
Even if you encounter such a difficult problem, how far did you manage to challenge it?
"(A-B) / (A-81)" * 100 (%)
By setting the index of , it becomes possible to self-evaluate in terms of the degree of self-challenge or the degree of effort.
The feeling of giving up and frustration you feel every time you take on a difficult problem in an advanced class can be mitigated by being able to self-evaluate your effort, and it can be transformed into something more than that. It becomes possible to feel.
If you self-evaluate yourself with Difficult Problem Iddards (%; degree of difficulty challenged), Difficult Problem Toytards (%;
Also, even if the toitard (%) goes down, you will be able to evaluate the level of difficulty, so you will not be depressed or discouraged.
Fights that you want to try again, and a strong desire to try another challenge of the same level.

In difficult problems, there is almost always a checkpoint somewhere that is not easy to pass, and if you encounter it right after you start deciphering it, in other words, your toyard (%) is extremely low. You feel really unlucky because you can't unlock the first step to move forward.
In this case, instead of giving up, you can evaluate the level of difficulty as a difficult question within difficult questions, and freeze the difficult questions in the refrigerator.

DETAILED DESCRIPTION OF THE INVENTION Embodiments for carrying out the present invention will be described below.
The present invention provides an 8 mm grid paper (9-81-729 grid paper) (5) composed of 729 grids of 27 × 27 grids, an arrayed number board (1), and an 81-grid perforated sheet (9 ), the mode for carrying out each invention will be explained.

(b) 8 mm grid paper consisting of 27 × 27 grids with 729 grid numbers (9-81-729 grid paper) (5)
Any one blank in the "Asa kara Sudoku" question treats nine numbers 1-9 (1 to 9) and displays/provides three types of numbers, so there are nine numbers per blank. In order to be able to write the numbers 1 to 9, the question and recording paper was edited on 8 mm grid paper by assigning 9 grids of 3 × 3 grids, 729 of 27 × 27 grids 8mm grid paper (9-81-729 grid paper) (5) consisting of grid numbers.

Since 1 blank consists of 9 squares of 3 × 3 grids, ruled lines are drawn for each of the 9 squares corresponding to 1 blank, and 1 block corresponds to 9 blanks, so 9 × Ruled lines are also drawn to separate blocks for each block composed of 81 squares of 9 squares, and ruled lines are drawn to form a total of 9 blocks.

The order of allocating the 9 numbers 1-9 in the 9 squares is the same as the order of the numbers on mobile phones and TV remote controllers, and as a convention,
From left to right , 1 , 2 , 3
Middle row from left to right , 4 , 5 , 6
From bottom left , 7 , 8 , 9
are allocated as

Then, the known numbers in the 1-9 blocks given from the question of "Sudoku from the morning" are entered in the corresponding block on the graph paper, which is the question and recording form, in the corresponding column (3 x 3 = 9, 9 grid).
Transcribe in large numbers so as to make full use of the 9 grids of the 3 x 3 grids.
Next, in the transcribed column (3 x 3 = 9, 9 grids), at the position of the grid assigned to correspond to the "numerical value" of this large number, a small identical Mark the numbers in red.
Therefore, within the transcribed known number column (3 x 3 = 9, 9 squares), ``large numbers'' and ``small numbers written in red'' will coexist in a proper way.

Once you have transcribed all the known numbers in the 1-9 blocks given from the question so that the large numbers and the small numbers written in red coexist in a way that is appropriate for allocation, the content of the question is a 27 x 27 grid. 8 mm grid paper consisting of 729 grid numbers (9-81-729 grid paper) (5) will be transferred on paper.

(b) Aligned number board (1)
Aligned number board (1) is affixed with number cards (4) on which nine numbers 1 to 9 are written on the surface of board (1) so as to maintain a regular arrangement order and arrangement position. It is attached and fixed so that it will not come off.

The order of pasting the 9 number cards (4) is the same as the order of the numbers on the mobile phone or TV remote control.
From left to right , 1 , 2 , 3
Middle row from left to right , 4 , 5 , 6
From bottom left , 7 , 8 , 9
I am pasting like .
It is also equipped with three types of non-numeric blindfold cards (3).

The method of using the arranged number board (1) is outlined below.
In the plane of the board (1), any one blank of the questions to be blindfolded is displayed/provided, and corresponding to each of the three types of numbers, the same three types of non-numeric blindfold cards (3 ) is used to execute the blindfold, the remaining numbers that are not blinded become the answer candidate numbers for that one blank.
The numbers blinded with the non-numerical blindfold card (3) are left untouched, as "blank numbers", while maintaining the regular arrangement order and arrangement position, and the above-mentioned one blank number It forms the 'blank' part that constitutes the answer.

In this way, the arrayed number board (1) displays and provides the numbers remaining unblinded on the surface of the board (1) as answer candidate numbers for the one blank, so that it can be edited as a question and recording sheet. 8 mm grid paper (9-81-729 grid paper) composed of 729 grid numbers of the above-mentioned 27 × 27 grids that have been reworked (5) On the paper, in the original arrangement order and arrangement position as it is, as a draft answer , can be transcribed and recorded.
In addition, transcribed and recorded as a draft answer with the original arrangement order and arrangement position as they are means that the regular arrangement order and arrangement position will be maintained.

Then, by repeatedly using the above-mentioned arrayed number board (1), the blanks of the questions are successively captured, and all the blanks (729 grids of 27 × 27 grids) of the questions and recording sheets are filled with regularity. Fill with numbers preserving a certain array order and array position.

In addition, the three types of numbers displayed/provided by any one of the blanks in the questions that are the target of the blindfold are:
The number inside the corresponding block ,
Numbers in the horizontal row targeted for the corresponding block "outside" , and ,
It is the number of the vertical column targeted for the corresponding block "outside".

The lined number board (1) is used in a slanted state by using a plate stand, etc., so the material used is a thick acrylic plate of about 3-5 mm, so that it can stand on its own with stability. In order to maintain the quality, transparent color seems to be suitable for the color of the acrylic plate.
If the color of the acrylic plate used for the arranged number board (1) is made transparent, the number cards (4) and the non-number blindfold cards (3) will have a refreshing feeling as if they are floating in the air. It can be emphasized and forms an exquisite contrast, so you can experience the fun and enjoyment of card manipulation.
When wood is used as the material for the aligning numeral board (1), one can enjoy the unique grain of wood and the soft natural beauty of annual rings.
In this case, a unique atmosphere can be created by printing or engraving numbers instead of number cards (4).
The number card (4) and the non-number blindfold card (3) are palm-sized and square with a side of about 65-75 mm, making them easy to handle.
Designs such as colors, patterns, pasted photographs, etc. of the non-numerical blindfold card (3) can be selected in combination to create various interesting designs.
Starting with simple 3 primary color cards and cards with punching holes, insects/fishes series, minerals/plants/animals series, topography series such as isthmus/strait/desert/mountain range, nebulae series, trains, etc. Railway and vehicle series such as airplanes, traffic sign series, people series, workers working in fisheries, agriculture, medicine, etc. series, product label series, nutrients series such as fatty acids, amino acids, vitamins, etc. can be enumerated.

(C) 81 square perforated sheet (template) (9)
Next, 8 mm grid paper (9-81-729 grid paper) consisting of 729 grids of 27 × 27 grids, which is a question and record sheet with all blanks filled in the answer draft (5) Enter the numerical information on the paper By searching (scanning) using the produced 81 grid-shaped perforated sheet (9), it is possible to decipher the numerous numerical information like spectral analysis.

The procedure for manufacturing the perforated sheet (9) with 81 grids is as follows.
Prepare a slightly thicker, slightly darker transparent or translucent sheet made of plastic, and use it as a question and recording paper, 8 mm grid paper ( 9-81-729 Grid paper) (5).

Since the 9 grids assigned to one blank or number column are squares, the intersection (6) of the two diagonal lines of the square composed of the 9 grids corresponds to the center position of the number column. do .
Accurately mark the center positions (6) of all 81 blanks or number columns (81) on the slightly dark transparent or translucent plastic sheet (7) prepared.
Then, at the 81 marked positions, 81 holes with a diameter of 9 mm, which are holes (8) of the size of a grid, are accurately drilled so as not to be misaligned.

Furthermore, if ruled lines are drawn to form 9 blocks in the same way as 8 mm grid paper (9-81-729 grid paper) composed of 729 grid numbers of 27 × 27 grids (5), 8 mm grid paper (9-81-729 Graph paper) (5) Complete 81 grid-like perforated sheets (templates) (9) that can be closely and interlocked dimensionally when superimposed on paper.
In addition, the slightly darker transparent or translucent plastic sheet uses a blue color. This is to avoid absorption of reddish light.

Next, how to use the 81 grid perforated sheet (template) (9) will be explained.
8 mm grid paper (9-81-729 grid paper) composed of the positions of the 81 holes drilled in the perforated sheet (template) (9) with 81 grids and 729 grid numbers of 27 × 27 grids ) (5) The position of the grid on the paper is dimensionally closely related and interlocked, so 8 mm grid paper composed of 729 grids of 27 × 27 grids (9-81-729 grid paper) (5) Numerical information on paper consistently maintains a regular arrangement order and arrangement position even if there is a large amount of the same numeric information, so the above-mentioned 81 grid-like perforated sheet (template) ( By searching (scanning) in 9), it is possible to decipher the numerous numerical information like spectrum analysis.

Numerical information recorded as it is and its arrangement information,
"By the numbers 1-9" , and at the same time ,
By block of 1-9 , and ,
For each horizontal line from the 1st to the 9th line, furthermore,
By column from the first to the ninth vertical column ,
Since it can be developed and sorted in an orderly manner, it is possible to narrow down the number of answer candidates and reduce the number as a result of logical development, leading to one number per corresponding entry field.
In the reduction process, it is also possible to develop and utilize new elimination methods in addition to existing elimination methods.

By the way, searching (scanning) with the above-mentioned 81 grid-shaped perforated sheet (template) (9) means that the dimension corresponding to one grid is 8 mm, so the 81 grid-shaped perforated sheet (Template) (9) is shifted (scanned) by 8 mm (each square),
"81 holes"
Starting with displaying/providing the number of '1' and 'blank' numbers/blank gathering status, sequentially,
The number of "2" and "blank" ・The blank gathering situation is
The number of "3" and "blank" ・The gathering situation of blanks,
・ ・ ・ ・ ・
・ ・ ・ ・ ・
Since it is to display/provide the gathering status of the numbers "8" and "blanks" and the blanks, and the gathering status of the numbers "9" and "blanks" and the blanks, the number information and its arrangement information are displayed. , you will be able to analyze and decipher them in an orderly manner like spectrum analysis, ``by the numbers 1-9''.
