To Start:
Mangle works by submitting random words to search engines, then opening the first result. Click on the M in the top-right hand corner to go to a new random web page.

Options:
The Country option restricts searches to webpages from specific countries, while the language will return pages written in specific languages. If used, these options work best if only 1 or 2 words are used in the search.

A custom word can be specified, which will always be used in the searches. Very useful to find webpages around a certain topic. Leave blank or as '*custom word*' to disable. You can specify extra parameters such as site and filetype restrictions in this field, as described in Google's reference documentation.

The number of words used in the search can be 1 to 5. Using more words will find more obscure websites, but also increases the chances of not finding anything.

Selecting safemode will filter all adult material from the searches. This is a filter provided by Google, and while no filter is 100% effective, it is very good at removing any questionable content.
