I was reading a blog post today and noticed a new form of captcha. The Click Captcha. The first one I saw was several circles and I was instructed to click the largest one. Easy enough. After a reload it changed to several squares:

You can view the demo here: Demo – Clickcha

Another interesting one: http://6tx.net/sc/form.php

These type of Captchas are easier than typing in several blurry letters and seemingly just as effective - especially if you cannot predict the shape.

Any thoughts?

But is it actually safe? Can't you make a program for solving them?

Well if it's limited to basic shapes (circle, square, triangle) and what it asks for is limited as well (small, biggest, color) then I assume it would not take long to figure it out. But if it does a lot more than those things then I assume it might take longer to do it.

Having variable instructions would help, or unusual shapes. The one I hate the most is the "type the letters with cat-position-x on them".

Weird shapes may also take away dumb people. Not everybody knows what an octagon is lol or any other weird polygon thats not as common.

theres also choosing biggest number inside a shape, i think its secure

eval(base64_decode("cHJpbnQgJ2kgbG92ZSBvbmUtbGluZSBjb2Rlcyc7"));
