Due to scripts and bots spamming the comments I've had to put the captcha on it. Good news, the Captcha should now not expire but refresh every four minutes. Also tuned to a less garish style. Cheers

small hint on this wonderful jigsaw: 4 as a must in all rows (or immediate conflict) - 4 in A2 or A3 solved with a short chain, obviously 3,4,5 as a must in all rows, 6,7 missing once,X wing on 4 solves most 4s etc - puzzle can be solved without additional candidates

I wonder which master mind (or AI?) can create such an elegant puzzle. Wow.

The code expires with time. After page renewal, it worked for me.
But the perceptibility of the black against red code is very bad.
