is where I try to answer them. I'm also directing Str8ts feedback here. Please feel free to drop me a note on the side of the page. Or you can email me directly at andrew@str8ts.com.

Hi Andrew,
a good new year to you and also for all players here.
will it perhaps be possible to see, for a same strategy, that the solver shows all the possibilities for a sudoku before going further ?

If you mean given strategy X cycle through all the eliminations that are possible with that strategy at that point, then yes, that’s something I'd like to do. It will greatly complicate the solver user interface which is why I've hesitated.
I do have complex heuristics and rules to try and return the "best" in each strategy but there is still a small bias to top-left bottom right as most searches scan that way.

I love doing the sudoku puzzle every day! It's very relaxing! It's been the same puzzle for about 5 days....what's up?

I have this problem for KenKen (run out of puzzles) but I didn't think I was low on Sudoku. What page or app are you using?

I'm no longer getting a new Daily KenKen when I click on that puzzle. I've been getting the same one for over a week. I tried closing the site and reopening, but it still happens. Thanks

Yeah, I've run out of puzzles and the generator is not working - since I last ran it I've made too many changes elsewhere in the code. Am trying to fix it and get some more puzzles up!

Superb solver, really intuitive. Thanks for developing this - from a long term Sudoku fan!

I had trouble getting the Daily Sudoku today. A window pops up and says, "Date requested after 31st Decem" but even after clicking "OK," nothing comes up in the puzzle. This is for puzzle # 2922 for January 1. I use Firefox on a Mac.

Sorry about this - and to everyone else. There were a whole lot of puzzle stock that happened to run out at the end of the year and then on top of that, a bunch of date checks which didn’t wrap into 2016 as well. Getting it together now I think. Appreciate the alert.
