Today's puzzle came with a dire warning to those solving on an iPad: "This puzzle contains an element that cannot be reproduced digitally. However, the puzzle can be solved and understood in digital format. ..." Undaunted, I launched in, quickly finding purchase with the guess SCOPE (9A: Brand of mouthwash) and its confirmation, SHAH ( 9D: Noted exile of 1979).
So anyway, long story short - or, at least not quite as long as it might have been - I eventually put in the letters of the Across words, which always ended up being "BY." As in, BOOBYTRAPS (46A: Staples of Indiana Jones films) and MADEBYHAND (29A: Artisanal, maybe), but I did not get the "Congratulations!" screen. Sure of my solution, and thinking of the puzzle warning, I thought maybe there was some technicality that was not allowing the app to register the solution as correct, so I went to xwordinfo.com, where I saw that I had a typo at 34D: Actor Idris (ELBA) and 34A: Lawful ends? (ELS). I had "aLBA," but in my (feeble) defense, I had considered "ELS" for 34A, but did not think the construction of the clue perfectly fit that answer. Wouldn't it have to be "lawfuls' ends?" or something equally tortured, to get the plural ELS? Hmph.
So that's my sob story. The puzzle's true solution, by the way, is to pile up the Ds and the VIs of the Down answers on top of one another so that they look like Bs and Ys. It's pretty clever, and, as yesterday, I wish that I had been solving on paper, but I'm still not sure whether or not I would have come up with that elegant solution, or whether I would have just left in the rebuses or the BYs and called it a day.
Overall, I really like the puzzle. There's tons of non-theme material that I like: STRASSE, SECLUDE, MAESTRO, STONEAGE, ANCIENT, GIST (56D: Meat) (tough clue!), and even M[DD]EGREE (42D: Operating requirement?). It's a lovely piece of work.
p.s. 1A: They're used for storage (BINS) gets a C.
