Friday Puzzles #139

So no 2012 puzzle this, and maybe some readers will be disappointed to see Kakuro this week. Also, it’s not technically Friday anymore (by a few minutes, but let’s not quibble over silly details like that) so I suppose an apology is due there as well.

Nevertheless, Kakuro is a type I really like, and I think there is plenty of opportunity to be playful with the type from a constructor’s point of view. I must say I quite enjoyed putting this puzzle together, but then again I’m a bad, bad person. Enjoy!

Friday Puzzles #92

So – Kakuro. Let the wall of silence begin! This one is genuinely hard this week too. Not hard in the lame way you get with computer generated Kakuro and you end up having to do lots of adding up with overlapping squares, but certainly hard enough to need a few “painting” steps. You might want to keep your advanced sudoku solving technique handbook with you as well. Enjoy!

Friday Puzzles #75

A.K.A. Tom Collyer finishes unfinished business
A.K.A. Tom Collyer keeps his promises (at least sometimes, at any rate haha…)
A.K.A. Who needs a list of pentominos by the side of a puzzle anyway?

So this is a tough cookie. But it’s worth it, I promise you. 75% solves beautifully well, and the last quarter is a bit of a head scratch. If it’s too much of a head scratch, you can probably trust my good nature and use a few hinted shortcuts to finish the puzzle. Enjoy!

P.S. A few weeks back I eulogised about how great my Marathon puzzles for the LMI test were. As it turned out, the test was somewhat of a disaster, with a high proportion of broken puzzles and plenty of egg on my face. That said, there were still some rather good puzzles and you can probably expect to see a couple of them reposted on my blog on weeks when I’ve not got a spare mo to do a semi-decent puzzle.

Anyhow, the Heyawake was actually broken – which made me die more than a little inside because if you skipped over the contradiction the mistake implied, it was in my opinion the best of the three puzzles. I did fix it, but it’s not the same :(.

Friday Puzzles #37

Sooo…after the roaring success of last week’s Kakuro puzzle – a plethora of hits and comments combined with an oh-so seemless transition from paper to laptop, it should come as no surprise to see more of the same.

Incidentally, I have asked the administrators of Warwick blogs whether I can get some better printing functionality. I suppose you’ll have to make do with right-clicking the image etc for now. Enjoy!

Friday Puzzles #36

So, I’ve never written a Kakuro puzzle before, so I thought I’d give it a go. Not exactly spectacular (and I’ve not quite got the formatting nailed), but then again not filled with lots of “gimme” clues so there’s a little bit to think about. Enjoy!
