Back in my blog post about MPPXXXviii I mentioned that Ken
Irvine had been staying at our place and he’d rather generously given me a copy
of his latest design which he’d called Migraine – now this must mean that he’s either
been let down this year and there isn’t a new grandchild to name this year’s
favoured design after… or some poor kid’s going to be growing up called Migraine
– you decide…
Anyhow – enough waffling, back to the puzzle. Migraine
breaks the mould a little being a 4*4*4 cube rather than Ken’s traditional 4*4*3
cuboid… when he gave it to me, he apologised for the fact that one piece was
sticking out a bit and suggested I put it back in properly… wry smile… yeah, right!
You’re being set up here!
That sticky-outy piece duly pulls out and a quick
examination of the hole it leaves behind confirms that if the piece were “simply”
inserted the other way around, it would be fine…
Of course, with all the other pieces in situ, that’s a lot
easier said than done, so it’s probably worth trying to take things apart
gently and seeing whether that piece can indeed be inserted correctly along the
way…
I’ll leave you to draw your own conclusions of course, and I
probably missed a trick somewhere along the way, but I needed to disassemble
the whole shooting match… and at that point recognised a few more of Ken’s
trademarks: a couple of the pieces have half cubies on them – that’s helpful! It
certainly was very helpful on Little Kenny and Little Bruce…
OK, so set about trying to reassemble this little guy and
you’ll find it isn’t too tough, as long as you don’t mind leaving out one or
two pieces. Insist on using every single piece and you have a much harder
challenge on your hands… one that has all the hallmarks of a great Ken Irvine design:
low piece-count, obvious final shape, not a lot of alternative positions for the
pieces and a fantastic “A-Ha!” moment…
It makes an excellent number three in the set… and it’s not
just me that likes it… Eric Fuller decided to make a run of 50 copies earlier
this month and they were all sold by the time I was writing this post just over
a week later… if you didn’t get a copy, it’s worth borrowing a copy from a
friend and having a fiddle with it – it is fun!
Ken continues to create these gems. Among other puzzles, I'll be sharing Migraine with my math colleagues next week, when we get together to create contests for high schoolers. Last year, one fellow did solve Bill Cutler's Splitting Headache -- I wonder how he'll handle Ken's latest...
ReplyDelete...I wonder if non-puzzlers might have an advantage? Let us know how they get on...
