Free simple sudoku game software for linux

Sudoku Savant is a simple GUI-driven application to solve and generate Sudoku puzzles through logical means.

Sudoku Savant generates and solves standard Sudoku puzzles with anything from 3x3 to 5x6 or 6x5 grids, using the following strategies:

- Singletons
- Locked candidates
- Number subsets
- X-Wings, Swordfish and Jellyfish
- Both Simple and Multi-Colouring.

These strategies should be enough to provide a step by step solution for any Sudoku puzzle that you are likely to find in a newspaper or magazine, although Savant can also resort to "trial and error" if presented with something really pathologically nasty. (This will at least confirm that the puzzles solution is unique.)

You may also parameterise or turn off the more advanced strategies, to see whether they were really needed.

Finally, Sudoku Savant lets you solve the puzzle by hand, providing hints, cell colouring, up to 4 pencil marks per cell, and the ability to high-light any incorrect moves. A partially completed puzzle can be saved in a simple text format so that you can continue solving it later.

FLTK Sudoku is an implementation of the popular Sudoku game (sometimes called Number Place) based on the Fast Light Toolkit. FLTK Sudoku features an infinite number of games and four difficulty settings, from Easy to Impossible.

Sudoku (pronounced soo-dough-coo with the emphasis on the first syllable) is a simple number-based puzzle/game played on a 9x9 grid that is divided into 3x3 subgrids.

The goal is to enter a number from 1 to 9 in each cell so that each number appears only once in each column and row. In addition, each 3x3 subgrid may only contain one of each number.

At the start of a new game, Sudoku fills in a random selection of cells for you - the number of cells depends on the difficulty level you use. Click in any of the empty cells or use the arrow keys to highlight individual cells and press a number from 1 to 9 to fill in the cell. To clear a cell, press 0, Delete, or Backspace. When you have successfully completed all subgrids, the entire puzzle is highlighted until you start a new game.

As you work to complete the puzzle, you can display possible solutions inside each cell by holding the Shift key and pressing each number in turn. Repeat the process to remove individual numbers, or press a number without the Shift key to replace them with the actual number to use.

Sudoku is normally provided as part of the FLTK 1.1.x source code.
