A very easy to use sudoku and good looking game. Combined with NoNumber's Modules in content plugin, this module makes a great stand alone page for your site!

Install was easy, quick, and error free. the display is simple and clean, does include a link back to their site, which is only fair.

One drawback of this extension (the only negative I can see)is that the width of the square is not flexible. It is too wide to fit in any of our side columns, so it's in a much less favorable spot, which is the only place the image will fit.

Other than that, it does what it says, and is a neat extension. If the admin had some control over the width, it would rate five stars.
