Users often find it difficult to identify the obscured words that a normal CAPTCHA uses for form submissions. Dice CAPCHA is a new way to reduce this difficulty, while still helping to prevent spam.

It works by asking the user to calculate a simple sum using the numbers displayed on a number of dice.

It is easy to use and can be added to an existing form in just a few lines of code. The CAPTCHA is a single simple image and will work in any browser.

The background colour and colour of the + and = signs are fully customisable using hex colour values. There are three colours for dice; red, green and blue. You can also have two different dice colours on the same CAPTCHA or have them chosen at random.

Update You can now have any number of dice you want – see http://codecanyon.steve-j.co.uk/dice-captcha/ for examples of 2, 3 and 5 dice.
