Hello and welcome! 
In this thread, we will attempt to solve the self proclaimed hardest puzzle on the internet: notpron.com.

The goal is to reach the final page, which requires figuring out how to move from one page to another.
There are over 100 puzzles in the format of the webpage. It has a somewhat eerie atmosphere, but it's not a horror game.

I've played this game from time to time for over a decade, but I've never got very far (~level 25). So this time, let's try to solve it together.

Rules:
- No walkthroughs. If you want to use one, please don't spoil the game for the rest of us.
- No spoiler tags. These will get really annoying really quickly, since most of the discussion will be about how to beat the level, sharing clues and brainstorming. The only spoiler tag that will be used is one containing the exact solution to the puzzle.
- I don't think it will be necessary, but let's limit it to a maximum of one level per day.

Official general hints:
- Always look for all hints you can find, and try to interpret them!
- A riddle consists of more than a picture!
- Try all to get to the next screen, no matter what. It's NOT a point and click thing!
- The url of the next riddle has nothing to do with the current one!
- Everytime you need Google, there is a build in search bar on the riddle page. No need on any others.

About passworded Stuff:
- no spaces
- no capital letters
- You won't see the password written in an obvious way
- You'll always get username and password at the same time or in the same way (except Level 13)

LEVEL 1

So, here we go: the first screen. It's more of a test to see if you're a bot than an actual puzzle:

i played a little and went to 4, its nice. well first level is self explanatory

Great idea for a thread!

Should we post our solutions and thoughts in order to get some discussion going?

Well I'll start with level 2 https://notpron.com/notpron/not/level2.htm .In the hint it says it is not a point n click solution. So the first thing i tried when I was playing on my phone was

My Solution


substitute the number 2 with 3 in the address bar on my browser. I figured the little hand showing the bar was a hint

And I was in the third level. At first I didn't know if I cheated or passed the stage as intended, but I replayed the level on my PC  browser and after a while I get this message "The door is closed. Trick it or reach level 3 in a different way. (Address? Where is the hand pointing?)" . Which shows that my solution is correct but also implies there is another way of proceeding ("Trick it or")

edit : sorry for the spoiler tag, don't kmow how to edit it out. Just remembered the no spoiler tag rule

You will receive this message when you hover the cursor over the doorknob. It's a hint that you shouldn't use the same solution twice.
And your method is indeed the correct way to pass this level.

Oh I see, I was curious why I didn't get the message on my phone, that explains it

So with the TAB key you highlight all the interesting areas in each page (including for example the doorknob in level 2, which is really helpful), but how exactly did it help you proceed kami?

If the webpage code allows it.

Press Enter after highlighting the area of interest.

Oh i see you highlight the number with Tab (can't see it when you do it) and press enter, that's tricky, must be the second way for doing it, I don't think it's an exploitation, you can't use this trick in the third stage. Kudos Kami
