Free sudoku kid software for linux

Sudokut is a command line solver for Sudoku puzzles. When supplied with a Sudoku string or file, it returns all possible solutions.
Sudokut takes approximately half a second to solve a medium force Sudoku by using an efficient algorithm that is guaranteed to find all the solutions. It accepts many options that implement various features (validity check, diff, suggestions, and probing).
Enhancements:
- two new solving techniques are supported: naked triplets reduction, hidden triplets reduction
- new -u option to test the unicity of the solution
- new -m option to modify the string

KSudoku project can generate and solve sudoku puzzles (of different difficulty level) using a randomized least-candidate algorithm.
The sudoku boards currently supported are 9x9 and 16x16: but the program is fully expandable since the algorithm is extendible to any general graph coloring problem (the board is in fact stored as a graph and the numbers are the colors)
In order to create a playable puzzle it fills a blank sudoku grid with a completed puzzle (randomly), then another algorithm (to be improved with some logical constraint) removes randomly numbers from it checking each time that the resultant puzzle has only one solution: it is a bit slower than logic-based elimination tecniques but it creates puzzles that are less straight-solved (more fun).
The GUI is user-friendly and requires KDE. Written in C++.
INSTALLATION
1. Open a shell in project directory (the one where this file is located)
2. Run "./configure"
(will install the program in /usr/local/kde, if you want to install in /usr run "./configure --prefix=/usr")
3. Run "make"
4. Run "make install" as root.
5. Run "ksudoku" (if does not start check point 2)
Enhancements:
- Added support for custom shaped sudokus
- Samurai sudoku
- Jigsaw sudoku, XSudoku, 4x4
- Undo/redo
- Added new export system (you can print multiple puzzles in the same page)
- File format is now XML
- Added new welcomescreen and settings dialog
- Internal structure changed

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.

php Sudoku is a Web-based sudoku game that includes 200,000 sudoku puzzles. It can be easily used on any Web site.

The project does not require MySQL or any other database.

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.

When you have the puzzle set up the way you want, click the Start Game button to start playing.

Random Game:

To have a game randomly generated for you, click the Setup New Game button. A new window pops up asking you to select either "Manual" or "Random". Select "random" and a new game will appear.

To build, use:

make -f Makefile.[system]

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.
