when are you folks going to provide a digital keypad (like USA Today and a rash of other sites), so I don't have to keep switching between my desktop keyboard and my mouse?

Hello! Since end of May there‘s been a bug on your IOS player for straits: Each time I fill in the numbers on the right side of the bottom row (first two or three from right) I get redirected to another page of yours. Bug or scheme? I‘m using iPadOS 16.7.8 on iPad. Thank you!

Fixed! Thanks for letting me know. Was a stray html element on top.
Hopefully the ipad will download the new version

Great program. Have used it for years. Use grader to see how difficult it is. Now grader comes up yellow on white. Hard to read

Hi Andrew,
Since 06/01/24 I am missing my daily str8ts on iPad. The last one was of 05/31/24 and is not refreshed when starting it.
Just a short-time problem?
Greetings Fritz

I've been messing about with feeds this week but I thought I'd preserved the ones for the '5 Daily Puzzles'.
Update: Now fixed.

Hello, I am using this site regularly to learn the sudoku tricks. Today, I tried kenkodu solver as 6 x 6 killer sudoku. But after few steps, it stuck on the candidates removing part and dont proceed further. I tried ctlr+f5 and clearing cookies. It didnt solve. Also can you also add email this board option in kenken solver also? Thanks

Hi rocky. I'm having problems with the 6x6 solver at the moment. Should install just like the 9x9 but for some reason won't do it. Am continuing to work on it.

OKAY Solvers have been updated to version 2.16!
You will need to download the latest page and scripts, which is simple to do. Press the keys [CRTL]+[F5] together to force a reload. If this does not work, you can clear your cache.

Can’t do this on my ipad

Andrew Stuart writes:

Wish I had an ipad to test with! What I do is update a version number on the included scripts which normally invalidates any cached version the browser has. Sometimes it can be a bit sticky on the ipad. Keep reloading the page?

Why the change in the format of the jigsaw printable version of the puzzles? It’s totally unusable as there is no space to write the candidates. Am I missing something?

I really enjoy your puzzles and am grateful for your website , but this change is very disconcerting as I am now having to hand copy the puzzles. Not a big deal in the general scheme of things, but still an annoyance.

Thank you for your help.

Kate

My bad. Was deleting a bunch of old stuff to keep things same. Jigsaw was linking to an old style sheet.
Check now!

KenKen solver stopped working: all browsers, all OSes. Ver 2.16. Ctrl+F5 no help. Click on "Take a Step" does nothing. Click on "Grader" gives

Problem grading this puzzle.
cl=36, sp=0, as=-nan(ind), w= 0.0

Please advise...thanks

Yep I broke it yesterday. Publish in haste, repent at leisure. Try now, CRTL+F5

Recently you changed the color of the tries from Bold Red to Red. This completely changes the strategy of the game. Please return to normal Bold Red.

Hi Glen. Need more info - not sure what you are referring to. Leave an email so I can respond directly

Load Sudoku: CLICK TO LOAD

On classic Sudoku hidden singles does not trigger the broken grid error message when two (or presumably more) values are selected for the same cell.

With the supplied broken 17 clue grid both 5 and 9 are highlighted for F9 then the 9 is promoted without regard to the 5.

Okay I’ve put in a trap for this. [CRTL]+[F5]
Situation I’m certain should only occur if the puzzle is broken (multiple solutions)
