Free sudoku 0.1 software for linux

Kats Sudoku is a simple helper program for solving Sudoku puzzles. Kats Sudoku starts with an empty board and prints all possible numbers in each field.

After setting a certain field to a number, it deletes all occurrences of this number in the corresponding row/column/block so that scanning of rows/columns/blocks for possible entries is unnecessary.

Otherwise, there is no logic, which means that finding the solution is still the players task.

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++.

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.

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.

GNOME Sudoku is a GNOME-based puzzle game. Sudoku is a popular puzzle Japanese logic game. GNOME Sudoku intends to provide a simple interface for generating, playing, saving, printing and solving Sudoku puzzles.

At present, GNOME Sudoku supports infinite undo, generation of symmetric puzzles with unique solutions, and basic features to help gameplay.

Su-per-Doku is a sudoku puzzle game dekstop widget for SuperKaramba. It has most of the features you would expect from a sudoku game.

It generates puzzles, provides hints (if required), allows you to note potential answers next to a cell, set the difficulty level, and make the computer solve the puzzle.

Sudoku, sometimes spelled Su Doku, is a logic based puzzle. The aim of the puzzle is to enter a digit from 1-9 in each of the cells in a 9x9 grid made up of subgrids of 3x3 cells (called "regions").

To solve a puzzle, each row, column and region must contain only one instance of each numeral, 1-9. You start the puzzle with only some of the cells completed. You have to fill in the rest.
