About this Website

This website was designed on the 5th June 2005 after my Sudoku crazed family drove me to write a Sudoku puzzle solver.

This site was built to showcase my work and also provide a resource centre for people to find 'good' sudoku puzzle and printable grids to use for working out the puzzles. This site has Samurai Puzzles, Killer Sudoku, Puzzle Solvers and Killer Samurai Sudoku which I thought might be useful to share this resource with other fellow Sudoku addicts.

This site was designed using Dreamweaver MX 2004. The site is composed using CSS and xHTML. It also uses the Server Side Scripting Language PHP for some of the more advance features of this site. The site is hosted by 4thewww.

My name is Daniel Mitchell. I am an avid programmer and web developer. I have learnt a variety of languages which include PHP, ASP.NET, VB.NET, SQL and many more. I currently involved with many freelancing project which usually involve the creation and implementation of powerful database driven websites. If you would be interested in my services then please contact me for my portfolio.

Since 5th June 2005 this website has been viewed 2,604,037 times. There are currently 5 people online. (Based on data in the last 5 minutes)

Update May 2012. The site has had a face lift using Bootstrap. New features have been added to make the site easier to use. Still amazed at how many people have visited this site. And yes, I still love solving sudoku puzzles.

Enjoy Sudoku!

Hi Daniel

I have just come across your site after a very long search for a solution to my problem .. and I am hoping you can help me! I have a website for parents (www.activityvillage.co.uk ) and have been offering "Sudoko for Kids" for a few weeks. They are very popular but took me ages to produce and the quality of the pdf files is not good. I am hoping to create more puzzles (including easy 9x9s, some 6x6s and maybe even some 4x4s to start kids off with) but need a way of generating the puzzles easily, exporting them as good quality gifs or whatever into Pagemaker, where I add graphics and convert to pdfs. If I can get it right I would like to offer a downloadable booklet for sale too. Please get back to me if you think you can help, with details of what you would charge. I look forward to hearing from you,
