Starting with the Sudoku solver we have recently
obtained we developed a Puzzle generator together
with an interactive game play. The result can be
run in a web page by means of Dogelog Player 1.2.0
for JavaScript. Both the Puzzle generator and the
game play were written in 100% Prolog.

Regin Filtering from SWI-Prolog CLP(FD) didn’t
make a dent for generating unique puzzles, all we
could do was provide 34 clues, and our solver takes
in the average 1000 ms. We also implemented valid
move checking by reusing the constraints and an undo
move queue via dynamic facts.
