Years ago I played notpr0n, which is a puzzle very similar, in which you use links, urls and other web-based "locks" to advance to the next level.<p><a href="http://notpron.org/notpron/" rel="nofollow">http://notpron.org/notpron/</a><p>It is also interesting for non-geeks to learn about how the internet (and computers) work.
Oh, come on -- don't cheat!<p>Though I admit I don't currently have the time to get far (I've gotten the first couple but have work to do tonight...). I love these puzzles, though!<p>I quite enjoyed going through the web penetration puzzle posted here a year or so ago -- where to access the next URL at each step involved a slightly trickier exploit (starting at just reading the HTML source, to modifying form fields, to tweaking cookies, etc.) -- anyone remember where this was?<p>It was educational (as well as fun), so at least I could excuse burning some time doing it.
Please use ROT-13 if you want to give answers; <a href="http://www.rot13.com" rel="nofollow">http://www.rot13.com</a><p>Vague hints are fine, but putting "SPOILER ALERT" right above the answer doesn't help; it's impossible to read past those posts to see the less giveaway hints.
Nice! Reminds me of notpron[0] which entertained me for weeks.<p>[0] <a href="http://notpron.org/notpron/levelone.htm" rel="nofollow">http://notpron.org/notpron/levelone.htm</a>
six b has me stumped. The obvious interpretation is that you need to do something with "4 down" and "2 across" from the crossword puzzle shown. But according to typical numbering, that puzzle wouldn't even <i>have</i> a "2 across".<p>Edit: OK, I got it. Tricksy tricksy.
