Uh, no, when you describe a pair you use the plural. “Pair of pants”, “pair of earrings”, “pair of socks” — these phrases do not refer to four of something.
I play board games and rpgs, so I spend a lot of time with dice and reading about dice. I don’t think I have ever heard a dice pair to reference multiple pairs of dice. My mind was looking for some weird die with a top higher than 6 since you need a pair that adds up to 14. Dice is plural but pair implies 2.
They should have said just the group of dice whose top sides sum to 14.
It's also a descriptive label we use when discussing numbered cubes. In the captcha's context, that's the meaning I've fixed in place - while I parse the rest of the text.
I'm seeing hints that the captcha also comes with a short time clock along with the usual locked-account punishment for failure-to-solve. Fast assumptions seem appropriate.
Reading the post and OP's comment, I think he approaches it the wrong way and actually try to count when a quick glance would eliminate 4 out of 6 options. If you see 6+5+4 you just know it's too high or 1+2+2 is way to low. Not much serious counting needed.
However, that 6/9 really threw me off and came across as terrible design.
An optimal algorithm that solves the normie's problem by completely ignoring it.
I.E. "you're holding it wrong"
Would you offer this solution to a 13-year-old using GitHub for a school project? Or a 60-year-old trying to keep up with tech? Or a busy parent trying to catch up on things after a long day?
I was looking for that but the line isn't visible on my computer unless I zoom in far. Maybe more obvious when doing the captcha for real and not looking at a compressed image.
Not from my perspective. I'm asked to pick a dice pair. I can't find any two dice that add up to 14.
