There are two types of humans on earth - those that fill in Captchas so that they can download pictures of cats and life changing apps, and those that fill in Captchas to spam and steal other people's cat pictures. If you are of the later type you have at your disposal several approaches to defeating Captchas:

• If you are a super-geek that communicates with machines in a language they understand (and I don't mean a sledgehammer) you can try and locate bugs and security holes in the code. Find a good one and you can probably simply bypass the Captcha altogether.
• If you are a genius with way, way, way too much spare time you can try and write an amazing character recognition software. Given the level of sophistication of today's Captcha technology, such software will have to be at least as smart as a profoundly stupid human with half a brain and functioning eyes. This brings me to the third method which, unsurprisingly, is also the most popular.
• Using VCHL (Very Cheap Human Labor) to manually fill in captchas on an industrial scale.

Dice Captcha was developed by a super-geek of Megaladon proportions. It is, thus, sound proof and will withstand to any known character recognition software. As for VCHL, well, if your content is worth so much that someone is willing to pay hoards of mechanical slaves to play with Dice Captcha, you might want to think about selling your company to Google. I can promise you, however, that if you choose the 'Homo-sapiens Dice' mode, it will slow down the mechanical turks to the point that most spammers and content hijackers will opt out.
