A open source SUDOKU creator and solver written in FreeBASIC.

SUDOKU needs little introduction. This is my version, creating puzzles
at three levels of difficulty, graded by solving technique. Level 1 puzzles
are playable using pen and paper, but would normally be graded as medium
level if published in a newspaper. Level 2 and Level 3 provide more of a
challenge for the experienced user.
Special tools are provided to facilitate solving complex puzzles, and a report menu item will create a text file the solving techniques used by SKB if the user wishes to study any individual puzzle in more detail. See the help file (in cross platform pdf format) for more information. Compiled programs are provided for Linux (Ubuntu) and Windows.
This program is still being developed, and new features may be added in future versions. Check back from time to time if you are interested in updates. Bug reports, feature requests etc. can be sent to sisophon2001@yahoo.com
