To know which one to click on, you have to add up all of the dice, in all of the six pictures, including upside-down/deliberately confusing numerics mixed amongst the dice.
You can do that in five seconds, for 5/10/15 rounds, without a single mistake?
Adding 4 digits is not difficult, but doing this fast enough to be accepted by the captcha system is really hard. I was not kidding when I said that if you need more then 5 seconds per round, you failed and must start again.
Five seconds is pretty crazy. It's not just an arithmetic problem, it's a visual recognition problem. There are plenty of ways this can go wrong, for plenty of disability reasons, many of which aren't even obvious to the person trying to solve them.
Nah, this seems like a really basic CV problem that should be solvable in milliseconds. The hardest part would be rejecting the sides that don't face up, but even that isn't a huge deal.
