Free sudoku tool 1.0 software for linux

Sudoku Tool is a sudoku game that helps you to solve sudoku puzzles. Sudoku Tool can generate puzzles randomly or puzzles can be entered manually.

Some of the features include random puzzle generation, pencil marks, and the ability to save games.

Manual Setup:

The game starts in initialization mode. In this mode, you are setting up the a puzzle that you got from a newspaper, online, ... You are manually setting up the puzzle.

To select a location, click a square with the left mouse button and type in the number you want to place 1-9, or 0 or space to remove a value you placed there previously. You can also change other values by simply typing a new number.

CSudoku is a command line Sudoku solving program. CSudoku project solves the popular 9x9 versions of Sudoku using Donald Knuths Dancing Links algorithm.

It was created as a fun exercise in computer programming and not necessarily to be a program useful to anyone in particular.

There are many other Sudoku solving programs that are more refined and have many more features than this program would ever dream of having.

Installation:

1. unpack csudoku-1.0.tar.gz
2. cd csudoku-1.0/src
3. run make

Usage:

To run the sudoku program you will first need to install it using the steps as outlined above. Now, assuming you are in the directory csduoku-1.0/src, invoke the command:

./sudoku < infile

where infile is an input file containing 1 or more 9x9 Sudokus. For the format of the infile you can check out the file top95. In fact you can use the top95 file to test the program. By invoking the command:

./sudoku < ../top95

you should see some input and output details and at the end under "Overall Statistics" it should read

...
95 out of 95 were valid
0 has no solution(s)
95 had unique solution(s)
0 had multiple solution(s)
...

If this was done successfully you can now use the program to solve whatever Sudoku puzzle is giving you trouble. Enjoy!

sudoku-perl is a Sudoku player that offers a board, assistance, and solving using a (text based) ANSI screen. sudoku-perl offers a simple alphanumeric board display that supports the 9x9 matrix.

It does not generate a Sudoku puzzle; for this, the user must look on the Internet, newspapers, Sudoku booklets, etc. and take over the sudoku initial setting from there.

However, it assists the user in solving the Sudoku by providing some functions, up to and including solving the Sudoku from the current board setting.

Sudoku solver application was created for solving a Sudoku with a backtracking algorithm. Instead of using a 9 x 9 matrix, it extends the matrix to 10 x 36 (10 rows, 36 columns), storing information in the extra cells.

The last row is used for keeping track of how many cells, for the current column, are still available.

The columns 9-17 (0-based) are used for storing the numbers which are still available in rows 0-8.

The columns 18-26 are used for storing the numbers which are still available in columns 0-8.

The columns 27-35 are used for storing the numbers which are still available in each square (counting from left to right and from top to bottom).

Sudognu is a command line sudoku solver and creator. Sudognu can display the logical steps it uses to find the solution. It can print four sudokus to a pdf page and it comes with example cgi scripts for integration into www sites (see sudognu @ work below).
This project is written in C and tested on Linux. In order to compile and install sudognu you need Haru Free PDF library.
Enhancements:
- This release applies the forcing chain after X-wing, swordfish, and jellyfish, improves the documentation, adds a -P option for reordering solution techniques, facilitates browsing of sudoku solutions, and adds minor bugfixes.

LibSudoku is a Java library for writing applications that deal with Sudoku number riddles. It contains methods for parsing numbers into convenient data structures, manipulation and information gathering, output to text and HTML, as well as some rules for solving given Sudokus.
It was developed in a test-driven manner using JUnit test-cases.
Enhancements:
- Improved one of the rules to catch more cases and added two more rules (including the XWing and a generalization that should catch most of other similar cases like the sword-fish).
- Added more test cases and fixed a bug concerning JavaDoc and JUnit compatibility.
- Some performance improvements.
