Puzzler's Bulletin 89

Get in the Sudoku Zone.

I'm back from the Asian Sudoku Championship where we witnessed Ken Endo bagging another win. Please welcome our new guest author, Sakulbuth Ekvittayaniphon, who wrote today's very hard X-Sums Sudoku for me to practise with. We'll warm down with Canal View and Scrabble Carpentry for the week.

Enjoy!
