Calcudoku puzzle forum

Uuhhmmm..... cool I guess?

That is so very strange...

Will check, first thought is an accidental overlap between timed puzzle ids and regular puzzle ids.

That said, a "no-op check" should never happen for a timed puzzle of course, I'm thinking that is the bug to be fixed.

update: that was indeed the case, fixed now

I'll reset that one 4x4 attempt for you.

A few days ago, around one week, I received one of those, a timed no-op 4x4. I thought It was an experiment to make those more difficult. I did not comment anything, I simply solved it .

So now you know it was a once-in-a-lifetime experience
