Also we have statistics showing that the rate of failures in pairing solvings is low.
Do you match by color matching as it is written in instructions after overing over question mark?
I didn't read. I really don't think this sort of thing should require reading, and I certainly wouldn't expect it from my users.
I got the assemble geometric shapes puzzle, and from the image in the corner, it looks like all I have to do is assemble one of them, not every single piece.
I would suspect your collected statistics, at this point, do not reflect the general internet population.

Yes that is possible. But it also means re-educating users to new puzzles.
It may be exciting to keep developing new puzzle types, but I doubt all of them will be friendly to end users.
What if there's a bug? Constant change = constant risk.

No, I didn't say that.
What I am implying is that not all spam is detectable.
I don't care about the "stupid bots" here. Essentially, I think your system is good enough to fend those off, just as a well designed CAPTCHA system probably is too, so I'm not debating over them.
It's the "smarter bots" that matter here, where these types of protection systems differentiate themselves. If you're claiming your system is better than existing CAPTCHA systems, you need to really show that it is above and beyond existing systems, otherwise there's not much point.

When this "cracking" is essentially a client side thing, I doubt you'll know if and when it's cracked.
Short of you guys actually finding a tool to do so.
Anyway, I don't really want to go there. I can't predict how good your changes will be, how timely they'll be, or whether they end up breaking anything - that's beside the point, but the only thing I can point out is the efficiency of current puzzles.

I think most of your customers will be more clueless than your own team...
You'll probably end up getting a bunch of "fake" claims from people who are being targeted by Indian spammers or other systems which use humans to solve these puzzles.
But I guess that's one way of doing things, and seems a lot more efficient than manually trying to monitor trends.

When we change captcha the customers that already installed it do not need to reinstall it.
I was referring to the costs of manual observation, which you've said you actually don't do (despite what it sounded like earlier), so it's moot point now.

Wait a sec... if the user select one type of CAPTCHA, forgets it, and that particular type is cracked, how do you respond? Change their selected type for them?

reCAPTCHA. They don't change it because they don't need to. But as it's hosted remotely, the capability is certainly there.
