> you should realize they're asking for the sum of all dices, not of any 2 dices.

How many assumptions have we piled onto the user-victim here? I've lost count.

Oof, I’ve never heard anyone say “dice pair” to mean four dice.

Now that's terrible design.

> Dice is plural

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.

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.

Your way of counting things will ensure you cannot solve this captcha I'm afraid.
