Many readers would be aware that Sudoku is a puzzle (craze) that has
recently appeared in many major newspapers around the world as a regular
puzzle.

(See http://www.sudoku.com and http://www.sudokufun.com/

An open source sudoku project exists with a Java applet available at
sourceforge: http://sudoku.sourceforge.net/)

Mathematica in Education and Research would like to issue a challenge to the
Mathematica community to create a Mathematica version of Sudoku: a package
that both creates Sudoku puzzles and solves them (either totally within a
notebook or via the GUI interface).

Please submit your Sudoku version as an article for Mathematica in Education
and Research describing the code and the (presumed?) challenges faced and
overcome in writing the code.
