read moreIf you've never seen curling in the Olympics, you need to experience it. At first glance, it may look ridiculous. And at second glance. Probably third, too.
But upon your eighth viewing, you'll be hooked! There's so much strategy involved in determining what graceful curving trajectory you'll aim for, and how your shot will move in real life.

Likewise, there's so much strategy in creating curving crossword answers. To best achieve an elegant and eye-catching arc, a little math comes in handy. SEE, LOOK! I TOLD YOU GEOMETRY, TRIG AND CALC ARE IMPORTANT AND HAVE ACTUAL REAL LIFE APPLCIATIONS! NOW WHO'S LAUGHING, HUH?
Okay, maybe it's more an art than a science, but it is tough to create the illusion of curvature inside a square grid. JUST AS IT IS IN CALC WHEN YOU'RE APPROXIMATING A CURVE WITH SEGMENTS!
Ahem. Sorry.
Long story short, the EMERALD and the DIAMOND are so pretty. The SAPPHIRE and AMETHYST, not so much. Given that CURLING STONES doesn't define what type of curve should be created, I'd have preferred giving up the circularity in favor for an exponential or sine curve or something easier to approximate in a square grid.
Novice constructors tend to tackle these tough grid constructions by erring on the side of gluey bits called out in editors' specs sheets, while more experienced folks lean more on esoteric vocab. SAPOR is a toughie for an early-week puzzle, for instance. I don't like either SAPOR or AM SO, but I'd much rather use the latter these days. You want to leave open near-zero possibilities for early-week solvers to say "that's weird." Overall though, it's a solid product, given the hard-to-incoporate four curved answers.
This puzzle could be confusing to the (many?) solvers unfamiliar with CURLING STONES, but as a snooty sort who can say he's actually curled before (I wasn't bad, if I don't say so myself), I appreciated the visual, the EMERALD and DIAMOND in particular.
