Standard Sudoku

The standard version of Sudoku to nine by nine grid, which contains completely solved the riddle played in each grid cell an integer 1:00 to 9:00 (included). The rule defines a right solution is as follows: Each of the nine cell lines (horizontal cell library), each number 1:00 to 9:00 times and only once included, then each column (vertical collection of cells) contain integer 1:00 to 9:00 only once and all three with three sub-group of cells, each number 1:00 to 9:00 time and included only once. There are nine sub-groups, three rows of three subgroups per line (each subgroup is a collection of three times three individual cells), which cover nine by nine grid cells.

Sudoku for children: four by four version

My version of Sudoku for Kids uses a four by four grid of cells where, in a puzzle completely solved each grid cell contains an integer 1:00 to 4:00 (included). Like the standard version of Sudoku for Kids requires that each row, column and sub-groups each contain integer 1:00 to 4:00. Sudoku for Kids In a subset is also a sector (the four quadrants above left, top right, bottom left, bottom right).

Sudoku for Kids: UI

I have withdrawn the game in the top of the page on the right side and shows an advertisement for our product only to the party. The four-quadrant grid of four different colors set to make it look easier for young children to groups of four cells that, when all four numbers are available.

Four buttons appear directly below the screen: “New” (start a new puzzle) / Reset (from the same puzzle from the beginning) / “Hint” (fill in a blank cell for me) / “Check” (incorrect display of the red blood cells or tell me if the puzzle completely solved). The “Board” and “Check” button is important for young children. Any child with a computer mouse and click a button to the puzzle, where value is asked for advice to be completed until the entire network if the puzzle is solved and can resolve the user click on “Check” is a warning message appears, welcomes the user to solve the puzzle and told him how many references have been received and how often “check was clicked, before the final time the mystery was solved. The hope was that the child remain until the “Tips: Play 0 / self test: 0″ can be viewed at the time the child for playing standard Sudoku ready.

Instructions are just below the game, not at the top. It is for a return of the users who should not be distracted by reading the instructions again.

Sudoku for Kids: The operation of the Web page

To the independent Web site, all the puzzles that the game is displayed downloaded by the Javascript in the HTML file (both Solutions and starting points) can be downloaded. The fact that the user’s browser must not communicate with the server, when reading the user can save the Web page on his computer and play later, but not to Internet.

The four out of four games for Sudoku for kids has to fill only 288 unique solutions (the legal means all sixteen cells). All solutions can be “forced” by the first four cells (four cells of the solution can be chosen so that only one of the possible solutions is 288 compatible with the values for the four first selected filled in the cells). Some of the 288 solutions are 12 different four-filled cells in the starting positions, and some 128 different four-filled cells starting positions. None of the 288 unique solutions can be in a position with less than four cells.

I decided not to its starting position with a minimum of four completed in the cells for two reasons. 1) Sudoku for Kids is a lot lighter than the standard Sudoku because of the small size of the frame of reference, it seems reasonable, or as hard as possible to do. 2) Any person who can play a simple puzzle, the “hint” to the additional cells before clicking fill manually fill in the cells.

I chose all of the 288 solutions with seven starting positions for the various solutions to “thousands of puzzles (288×7 = 2016 to implement). The encryption I have for every puzzle elected an ASCII character used for each cell to describe to sixteen characters, the entire network. The sixteen characters each solution are ‘1 ‘/ 2 “/ 3″ / 4 “and the sixteen characters starting position and ‘0′ s (later displayed by the Web page as an empty cell). Any solution with seven starting positions is in JavaScript by a string of length 128 characters depicted ((1solution seven starts) x16 = 128).

Here is an example of a string that one solution and its seven main headings:
PZL [147] = “31242431134242133004000000000210300000010040020001200000000040030100003000024000002004000300001000042000030000100000043010020000″;

This is not very space-efficient method to represent data, but all the 288 solutions, and their starting positions require only about forty kilobytes of data transferred to the computer user. Compared to the hundreds of kilobytes for downloading images related to this product announcement, the forty kilobytes not significantly affect the user experience required. Representing the data as ASCII text data manipulation by JavaScript functions simple.

Here’s what happens when you want to track down the HTML / JavaScript if you click on each button (click on “Sudoku for Kids” in the resource box of the author, then display the “code” in your browser)

New (function calls NewPuzzle):
1) Create a random number 0-287 to select one of the 288 unique solutions.
to take 2) a random number of 0-6 one of the seven starting positions for the solution.
3) are set “download solution” and “startpt” with parts of the forty kilobytes of data (or any part thereof is used, as determined by the random number generator in steps 1 and 2). “Solution” and “startpt” are each arrays of numbers sixteen (values 1-4 and 0-4 for the solution startpt).
4) Call the function Reset Puzzle (see button on the page).

Reset (Reset Puzzle function calls):
1) Choose the font color to black for all cells (perhaps red if incorrect).
2) For all cells, where part of the starting position to leave the number and the complete cell read-only, otherwise empty cell.

Hint (function calls HintPlease):
A) repeats the generation of random numbers 0-15, and it corresponds to an empty cell, or trying until you have 1000 times.
2) If you can not find an empty cell in step 1, go through each cell 0-15 in search of an empty cell.
3) If a blank cell, copy the value of the corresponding cell in the “solution” for the cell to find in the grid.
4) Increase the number received tips.

Check (Check puzzle function calls):

4) Increase the number of self-test.

Sudoku for Kids: Creating the Puzzles

I have a “C” to the strings used by the JavaScript to generate solutions, and constitute the starting points. You can use the code “C” Source PHP / SudokuForKids.c on our website a link in the resource box of the author. You can freely use this code for legal purposes, without restrictions, but without any warranty.

The code begins with 288 Sudoku you will find unique solutions for children and for every solution, it tries all possible combinations of four cells and from testing, the initial positions can only result in it ending solution. After finding all possible starting positions for all solutions, each solution, and he wrote seven starting positions with a file as a string in the format outlined above relating brought (see [PZL 147] = “312 …” above).

The structure, which makes the children Sudoku includes a three-dimensional array with all possible values that can occur in every cell of the grid (elements [4rows] [4columns] [num_vals_still_poss_for_cell]). When a puzzle is solved, num_vals_still … equal to 1 for all cells. SudokuSolver is a recursive function (it calls itself), guess that all solutions “will take” every possible value of each cell one after the other, then calls the proposal “with puzzles (num_vals_still. .. for this cell is equal to 1 and” proposal “is now the value of the cell), ending a branch of the tree when it .. an intractable position (for some meetings num_vals_still. cell is equal to 0, which means that some earlier proposal was not correct).
