Jigsaw solver shows grid, but doesn't populate. Have tried it in multiple browsers and both Windows and Fedora Core Linux. No joy. Thanks for doing what you do.

I know I broke it in the last second - very last update my FTP uploaded a file with zero bytes. Then I went out as a man with a strimmer was right next door. Duh. Fixed now, have another go!
Thanks for your patience

Good morning, Andrew,

playing str8ts for many years I was shortly irritated about the new look since round about 3-4 days from now. I´m playing with keyboard and using the NumPad with the right hand and TAB and SHIFT-TAB with the left hand for moving horizontally (vertically can be down with arrow up/down).
But since the new update the SHIFT-TAB is not working anymore: the focus runs out of the actual game to the website (one press on SHIFT-TAB leads to the "step-by-step-solver link" above the puzzle.
So now I have to use the mouse to move to the next left field - that is time consuming and not comfortable.
Can you please have a look if you can reimprove this again?
Thanks a lot and regards

Wolfgang

Which player?
One on str8ts.com or the one on str8ts.de?

On str8ts.com:

Let me first check you've seen the "cog" icon and changed it to "keyboard input". Easy to miss when the default changes to the number pad

On str8ts.de

This was always number pad but I changed it to allow arrow and tab to move cells. Can you do that?

Sure we can sort it!

Hi Andrew,
Thanks for all your efforts spent.
Today, 15th June, the puzzles, str8ts, can’t be played. The first row is show at the bottom of the window. I tested two browsers. No difference.
Any idea what has changed.

Regards
Greg

Okay I've gone out and bought a second hand iPad. I can see the problem. After a lot of guessing (no mac to debug with) I found out Safari doesn't like 'aspect-ratio:1' and the css needs the height calculated. Ugh. Also fixed the squashed timer.

Hey there,

for many years I'm a true fan of your site. The last update however, is not compatible with safari - what a pity. I hope you'll fix this soon?

Hi,
thanks for many years of puzzle fun.
Would it be possible to add the same settings the daily str8ts has into the daily Sudoku as well? As someone mostly using the keyboard for solving, it is very difficult to control now with just the numpad on the side.
Thanks!

Andrew Stuart writes:
The same settings do exist. Use the new cog icon. However these settings don't travel across domains - so you need to set your settings on each site separately. Should work, email me if not

The solution display page is displayed out of my monitor screen to the right of the main page and therefore not visible. It used to show as a separate tab on the browser web page. What happened to this option?

Andrew Stuart writes:
I thought I should check before replying because why not use the horizontal scroll bar. So I checked and turns out the type of DIV I was using didn’t trigger it – so yes it is inaccessible if your screen is too narrow. Bit of an oversight. Refresh [CRTL]+[F5] and tell me if you can at least see the new blue button. If so, this will move it over to the left. If not will have to use an @media and put it there.

Not a bug but a question:
Do you ever plan on adding custom/arbitrary box shapes to the jigsaw sudoku solver, similar to the amount of flexibility of the killer sudoku solver?

Andrew Stuart writes:
Yes I do. It has been creeping up my job queue forever but I think I'm ready to tackle it now. Watch this space!
