There are three Castle fields on this page. The first, is a simple type the random number in the box. The second, type the current year, using the date function to obtain the current year. The third is a honeypot, and is hidden using CSS. You will also notice that you only have five minutes to submit the form.
A program could be configured to treat a time out the same as a wrong answer (the case for the first field), or differently (the second field and third fields).
Mostly handcrafted by Michael, this website was designed to standards, with the highest quality in mind, and in result. The code and content is freely available.
