I don't solved 1234+567+89 (I don't like these variants. All these mental calculations overheat my musician's brain

) and Pi sudoku. Perhaps this evening...

Agreed - I can't for the life of me work out how to solve these with anything approaching elegance and fluidity, or even without scribbling down lots of sums in what is essentially trial and error. I have a mess of notes and calculation by the side of my printed page, and I'm impressed by anyone who claims to solve these relatively cleanly. I'd like to know how it's done! Ditto calculo-doku or whatever the current Krtek cup is.

N.B. as a maths researcher you should take it as given that my arithmetic is lazy and prone to all sorts of errors ;)

Pi sudoku solved.
1234+567+89 solved too. Not very cleanly

, but perhaps I didn't thought enough about logic of these puzzles (like: when the last digit of a sum is 5, sum of the 3 units is 15 (5 or 25 isn't possible),...)

I didn't like calcdoku, but I think I'm in progress

Quite often the 1000's place column of 1234 gets solved immediately.

Interesting fact: the top 10 all come from a different country.

That is a very interesting observation indeed.
Thanks for pointing out.
