Thanks Pan and scchua
A very satisfying crossword, but was it a Quiptic?
Some of these were very easy from the definition and some really tricky. Perhaps on average a Quiptic, but more challenging than the brief asks for? Having said that I thought it a lovely puzzle with some great surfaces. I also liked the way the whole clue stuck to a theme e.g. for “wheelchair”, “innings”, “rent” and so on. By contrast “spin doctor” has the feels of a few random bits thrown together. Many carefully thought-out clues and I suspect Pan went back over these refining the language and improving it all. Nicely done and thank you scchua for the illustrated blog.
I like the fact that you felt the need to define ‘parse’ for all us crossword addicts. 🙂
Pan made up for the underwhelming Chifonie today
Excellent cluing throughout
Thanks all.
As TheZed says, a mix of easy and tough clues. About a dozen went in right away, but most of the rest took quite a while to tease out. For the second week in a row, a nice puzzle that seemed a bit more challenging than a Quiptic should be. Fun nonetheless, so thanks to Pan and to scchua for the interesting Parsee photos.
I didn’t know the distress signal and wonder how many did.
Good puzzle, a little tricky in parts but well clued overall.
Thanks Pan and scchua.
Robi@6 … I also didn’t know it, but I think it has come up before in a puzzle somehow – so the reminder felt familiar. Like Deja Vu all over again.
Like copmus, I was less-than-whelmed by today’s cryptic, and found this far more satisfying. A pleasing mix of write-ins and clues with a bit more bite. Some of which I couldn’t completely parse – so thanks to scchua for the clear explanations. (btw would the young Parsee be Freddy Mercury? He’s the only Zoroastrian I can think of. Or is this one of those blindingly obvious things that one isn’t supposed to actually answer?)
I grinned at INNINGS. Thanks to Pan for a fun solve.
I found this quite difficult for a Quiptic, but very satisfying in the end. I’m another who didn’t know MAROON, and I’m embarrassed to admit that I failed to see the hidden word in appRENTice (although I got the clues from the definitions). Among many good clues, I particularly liked the simple, elegant construction of 12a (CRUSOE)
My favourites were WHEELCHAIR + SPIN DOCTOR.
Thanks Pan and scchua.
Wellback@10, answer to a: yes, b: no.
Thanks scchua! I generally get to this blog so late in the day that all the obvious points have already been made, so I was a little surprised that no-one else had mentioned Freddy Q – hence my uncertainty about raising the matter…
Whilst it was amusing to see that ‘integral’ is an anagram of ‘triangle’, I don’t think that ‘integral’ and ‘basic’ are at all the same thing.
