I'm eventually going to move everything from here to http://sudokuban.sourceforge.net.
If you're looking for SudokuBan on the Linux Format 76 coverdisc, it's called sudoku-sensei-1.0.tar.gz. The name is different, but the software is otherwise identical to SudokuBan 1.0.
Sudoku Sensei has now been renamed to SudokuBan. A project called Sudoku Sensei already existed, and is much better suited to the name.
Keep an eye out for LXF 76.
SudokuBan allows you to view, create, edit and solve Sudoku puzzles.
For a description of Sudoku, see the Wikipedia article.

To install and run SudokuBan:
The program starts up with a blank 3x3 puzzle. You can enter numbers by selecting a square and typing a number, or by right-clicking on a square and selecting from the menu. The Presets option is selected by default; this means that any numbers you enter to begin with will be part of the starting configuration of the puzzle. Turn this off when you've entered all of the given numbers.
To create a random puzzle, click the New button. Hover the mouse over an option to see a description of what it does.
To load an existing puzzle, select Open from the File menu. The
puzzles directory distributed with SudokuBan contains some sample puzzles of different sizes, roughly ordered by difficulty.
If you get stuck on a puzzle, try some of the hints:
SudokuBan requires the following to be installed:
It should work on any platforms for which the above dependencies are available (essentially Linux and other UNIX-likes, and Windows). It has been successfully run on Debian, Ubuntu, SUSE and Windows XP.
Download sudokuban-1.0.tar.gz, extract it, and follow the instructions.
To get the latest development version (be prepared to wait):
bzr branch http://rightside.fissure.org/sudoku/sudokuban.bzr
This program was originally written in search of a Linux Format bounty, but it's far from perfect, and there were a few features I didn't get a chance to implement, so here is a list of things that will be considered at some later stage. Especially if there's interest from the outside world.
SudokuBan uses a text-based file format, normally with extension
.sku, defined as follows:
Note that any characters other than digits, dots or asterisks, including line breaks, are treated equally as separators. It is generally useful to arrange them in a way that resembles the board itself, but this isn't necessary.
An example puzzle (this represents the board shown in the screenshot above):
3, 3 +------+------+------+ |*6 . 1| . 4 9|*5 2*8| | 2 .*9| . .*8|*1*6 4| | 5*4 .|*1 6*2| 7*3 9| +------+------+------+ | .*1 .|*8 . 3| . 7 .| | 8 . .| . . .| . . 1| | . 6 .| 7 .*1| . . .| +------+------+------+ | 7 . 4| . 1 .| . . 3| | 1 . .| . . .| . . 5| | . 9 .| 2 8 .| 4*1*7| +------+------+------+
