As many of you know, I have been a member and an administrator of the Daily Sudoku (DS) site for about ten years now. I have recently become very disenchanted by the indifference of the site owner to that site's Discussion Board. I fear the discussion board or the entire may simply disappear, as has happened with a number of Sudoku sites. In fact, Dan (ArkieTech) started posting his puzzles here because DS went down without explanation for a number of weeks.
But, DS has proved to be durable, and the site has a loyal following. I do fear that it may just disappear, and have been trying to figure out the use cases that people find most beneficial. To that end, I have enlisted Helmut (Nataraj), Marty, and Jason.
One feature of DS that people value is Draw/Play (DP). It does three important things that I can see:
1. It is an online solver that provides hints to do the basics plus X, XY, and XYZ wings.
2. It prints puzzles on a half page in a pleasing format.
3. It generates bbcode text that can be pasted into a discussion board message that makes it very simple for others to open and solve or print puzzles in Draw/Play. Dan uses this feature with every puzzle he posts.
What would we do if DS disappears?
Well, Nataraj (now known to be Helmut) created a formatter to post puzzles to DP. He has also created his own site, that has a "Sudoku Helper" that offers tips but is not really a solver. It follows the philosophy of "teach a man to fish". Helmut has now enabled my imagined use cases in his formatter
EDIT: The correct (new) link is http://sudoku.saueregger.at/HSH/HSF.htm
and in his Sudoku Helper
His site is here, and it has very interesting Daily Puzzles of various levels:
In my next post, I will show how all this works.
