Hi!

Everything about Sudoku that doesn't fit in one of the other sections

Hi!

I have not given sudoku any thought for many years, but I stubled upon a YouTube video explaning Skyscrapers, 2-String Kites and Empty Rectangles and got hit by nostaligia. :)

Sudoku-science complete took over my life back in 2005-2007 when I was supposed to write a master-thesis in Musicology...

Finding the worlds 3 first minimal 39 clue sudokus got some attention from the media, with the result that I was invited to give a talk about it at the (at the time) arguably coolest tech company in Norway, Tandberg.

After the talk I got offered a job, and a completely new career-path was born.

Going through being acquired by Cisco on 2010, I was part of a group of 10 that left the company in 2012 and started Pexip.

And only 2 weeks ago Pexip got listed on the Oslo stock-exchange, and are headed for world domination :)

But it all started here for me.

Thank you!

I still have a copy as well, was debating on advancing it further but got aide tracked with my own, the tool i like the most is the easy grid transformations although it lacks a direct transpose (or diagonal reflection) still a handy tool just for these functions.
Some do, some teach, the rest look it up.

Yes ! Sudoku Architect does lack the diagonal transpose ....one cant have everything I suppose - but it does swap the rows,columns,bands and the numbers very neatly !
The isomorph filter , by combining .txt files is exceptionally reliable.
