Friday Puzzles #231

Greetings to all my dearest readers, and firstly apologies tor missing the past 3 weeks.

On the 4th of October I had intended to put out a Twodoku, but late in the design process found a problem with the puzzle and had no time to fix it before I had to travel to Birmingham for the weekend.  I'll see what I can do with that to publish it soon!

On the 11th October I was travelling out to China to participate in the 22nd World Puzzle Championship and 8th World Sudoku Championship.

On the 18th October, a wonderful week was coming to end, and I was much too busy to be able to put out a puzzle.  Or find away to access the blogger service in China!

Anyhow, you can certainly expect some kind of championship report in the next week or so, but for now, let me crack on with Daily League business.  This week, blackout sudoku, which shouldn't prove to be as challenging or fiddly as this type potentially can be.  In fact it's probably safe to say that you won't be seeing too many more challenging Sudoku puzzles from me until sometime next summer.  Enjoy!

P.S. If you've ever wondered what a bunch of Sudoku authors, from Monday to Sunday, looks like, wonder no more!

Most of my Killer Sudoku end up having quite a pronounced extra-regions feel to them, which I think is something that really sets them apart from the crowd.  However, this week I wanted something more along the lines of a decent (non-computer generated) Kakuro.  The implied similarities are more subtle and less trivial than the fact both Killer and Kakuro involve adding up, as I'm sure all my Dearest Readers already know, even if they have happened to have been historically unmoved by Kakuro.  Enjoy!

Thermo sudoku this week.  Numbers placed must increase from the bulbs.

Karel has also asked me to mention that there is going to be another Sudoku Cup this weekend - more details here: http://sudokucup.com/content/practice-puzzles.  And whilst you're there, you'll doubtlessly want to play Daily League puzzles online.

EDIT: please note an earlier version of the puzzle had the wrong length of thermometers in Row 1.  Sorry!

Outside Sudoku this week - the clues outside the grid are placed somewhere within the first three cells in the corresponding direction.  There is a backlog of Daily League PDF's that hopefully I'll be able to get to tomorrow.  Nothing too hard here, although you'll want to watch your step at a couple of points.  Enjoy!
