"Not user friendly"
date: May 6, 2009
This is about the least user-friendly implementation of sudoku that I could imagine. For one thing, no notes are possible, which becomes more than a little tedious for the later levels (*you* try aligning all those numbers in notepad...). Also, often when I clicked on a square, the possible numbers would flash and then disappear again. It seems that there is a magic sweet spot that you have to hit to get it to stay.
Just a few modifications would alleviate these issues: the ability to add multiple numbers to a square, and keyboard controls (arrow keys and/or tab to navigate and entering numbers directly singly or multiply).
It appears that there is at least one bug left in puzzle generation: the solutions to puzzle 15 and 16 were *exactly* the same (rotated 360 degrees, apparently).

I was so happy to finally get bonus points on 16 ;p, though it took me one third of the time just to enter all the numbers I had in my scratchpad from the last puzzle using the mouse.
As an example, I include an intermediate state of my notepad workings on the above puzzle. It looks aligned in the preview box, though sadly I have little confidence in it remaining so after I submit.

That is a bit much to keep inside my head at one time...
