New Feature: Create & Share Puzzles!
I have added a new feature to the site that allows for portable sudoku puzzles with state preservation. If you see a screenshot of a puzzle you'd like to play, or maybe help someone else with that puzzle, you can use the new Create & Share feature I've added to do just that.
Create the puzzle, save it, mess around with it, and then share it. Sharing a puzzle will retain the entire state of the original puzzle, the numbers you put in yourself, and even hints! You could even use it to play a puzzle on one computer and then shoot yourself the link and pick up your puzzle where you left off on another computer. This feature only works for desktop and custom or shared puzzles cannot be verified with the Check button.
Give it a whirl today!

New Video: Introductory Sudoku Walkthrough Part 2
This is part two of my introductory sudoku walkthrough where I apply what I covered in part one to solve one of my very own difficult puzzles. We address things like pointing pairs, naked pairs, and x-wings, but we do so as they naturally and organically reveal themselves within the grid as we solve the puzzle.
If there is a sudoku player hiding within you, I hope this video will help coax them out!
You can play this very puzzle featured within this video right here.

New Stuff!
I pulled the site out of the stone age. It should be reasonably responsive on all devices, now. The words "reasonably" and "should" are doing a lot of heavy lifting here, of course. Be sure to checkout some of the puzzles I have made.
I have some easy puzzles, some medium ones, and a lonely hard one, all by itself. If there is a video icon next to the puzzle, that means that puzzle has a walkthrough!
