In case you haven’t figured this out yet: have you found a phrase? If so, remember where this whole puzzle started.

FYI, I did figure this out! A hint, for anyone struggling with it: do look at everything, BUT don’t worry about combing through every word of the docs for a buried clue. You won’t find the answers there. A bigger hint: really make sure you’ve read through all the files in prog. Lastly, don’t forget to type in “help” if you’re stuck to review all the commands available to you!

And, to M: I’ve now finished the whole thing, and I had so much fun. Please write another book!!!

Question about H4XOR: Any advice about how to reset the password of the NSA server? It says the information was sent to the NSA IP address, but I can’t figure out what to do from there. Any help is super appreciated!

Did you ever solve the third 50LV3R puzzle? If so, what are we suppose to do after?

HELP!!! I am stuck on MU51C14N. I have solved for Twinkle Twinkle Little Star but no matter what I do I can't seem to get Happy Birthday or Yellow Submarine. I have even tried to follow the sheet music I looked up on Google but the available notes don't seem to correspond correctly. Do they begin in weird places? I am pretty sure that Happy Birthday starts at the second "Happy Birthday to You" instead of the beginning. Any guidance would be soooooo appreciated! I have solved all the other theorems and only have this one left!

i figured out magician. now i cant figure out the password/favorite song.

hey can anyone help me, im stuck on the third phase of magician

So I figured out 50LV3R level 2

Each gold symbol represents a regular letter. When you click on a specific gold symbol and everything freezes, you need to then click on the symbols corresponding letter. Do that for all the golden symbols. Now for the hard part, how do you find out what the symbol-letter mapping is... I have no idea. If someone finds out, let me know! You can either brute force or if you're desperate you can do what I did and sort of cheat. If you're desperate see the hint below

So you're desperate and want to cheat the system? Well it might be time to look behind the curtain. So get caffeinated, grab some Java and go spelunking

And hey M, so long and thanks for all the fish . At least until you release the ULTIMATE version

Can I get a hint on 50LV3R level 2

This is what I got so far:

1) The glowing symbols repeat in a regular repeating pattern. Meanwhile all the regular symbols do not appear to repeat, or at least not in phase with the glowing symbols

2) The symbol seem to be a combination of greek, cyrillic, and international pronunciation. It took me a while to identify all the glowing ones. Each symbol corresponds to a sound. So I tried to "pronounce" the glowing symbol pattern but it just sounded like gibberish to me.

3) One of the glowing symbols is a "click" letter. So I thought maybe Im supposed to click that one. But that didn't work

Should I be focusing on the glowing symbols or all the ones in the background? Also I have no idea what people mean when they said they brute forced through this one. I've clicked on every symbol and also kept pausing it to see if there was something in the background symbols

Can someone please give an additional hint about 50LV3R level 2?

We see the 27 symbols but not sure what if anything to do with them.

in H4x0r, if you go into the music folder, the facade song from the Jekyll and Hyde musical is in there. I'm not sure if it's important or not but I love how it calls back to fancy suits and shined shoes from the original 'what is the master theorem'

And I’m back. This is more a desperate plea then asking for hints. I was working on H4Ck3R and got through most of it, however, it just doesn’t want to work. I’ve gotten the Alias (starts with o and ends with a), made a new key, and encrypted it with sha3, then sent that. im not really sure what Im missing, unless I have to encode his Alias some other way before encrypting it. Any hints would be helpful, because I can’t see what I did wrong.

Thanks. Gotta say tho, had to be stupidly specifically right.

You're basically there, your translation is just very slightly wrong

Hey, don’t know if anyone’s on here, but me being my usual idiot self can’t seem to get to the first puzzle, I’m stuck on the answer box on the website. I translated the leetspeak to “who are you calling a noob? I’m the leetness” but nothings happening when I put it in. What stupid mistake am I making?

My notes on each puzzle (no idea how many people read these)

Magician: Don't overthink. Look for a simple method. There are several clues in previous comments that should be able to get you there if you wind up getting stuck.

Hacker: By far my favorite puzzle, and one I surprised myself by solving without reading too many hints. Be persistent, read everything, read files even if they're unnecessary (I would spend hours talking to M about his dreams and they're significance.

Navigator: Definitely spent too much time on this one and should have had it sooner. Study the symbols closely.

Musician: Struggled finding an app to help me with this, but got it eventually. Loved it that someone designed the final song to be unshazamable.

Soldier: Got this one on the first try, and no one else seems to complain about having trouble with it, so have to think that using a little bit of logic is the only solution.

Artist: The people at the library probably thought I was crazy for holding a sheet of paper up to the monitor and tracing, but that's what I did to help.

Scientist: Got this one because one or two people left useful comments behind.

Spy: Got it on the third try. You need to guess incorrectly once or twice to reverse engineer what's going on.

Solver: Got the first puzzle accidentally because something glowed. Brute forced my way through the second puzzle. Third puzzle, still working on it. Not sure if it's a giant Polybius Square, Checkerboard cipher, or something else entirely. Clicking on a question mark causes a grid to stop, but not sure what you're supposed to click on next. Will keep trying till something works.

Sadly, I am still hopelessly stuck on Mu51c14n. I any help would be greatly appreciated, but I think this is one where it is near impossible to do clues for. I would love to get to see the end on M’s amazing book, so sadly I feel as if my last hope is to just ask for the code to complete this puzzle. :(

Oh my god... after the first book, I was feeling pretty good about myself. Then this book existed and gave me a run for my money. This book certainly isn't for the faint of heart, and there was a scare at the end where a browser error prevented me from entering the final answer, and it took me months to solve 4C13NT15T because I was being stubborn about brute-forcing it, but I just managed to do it. GG, M. GG.

(please make a third book)

Okay, someone tell me if I'm on the right track: In the second grid in 5OLV3R, the letters form a looping message. I've deduced that some of the characters are Greek and some others are Russian, but that weird 8 thing and the backwards 3 trip me up. I can't figure out what alphabet they're from, and when I try to translate what I can, it comes out with something that sounds like it COULD be a real word if I just changed some of the letters out for others. Am I being an idiot or whatever the opposite of idiot is?

Here’s a hint that’s appropriate for where you’re at: If you incorrectly guess the password enough times, you can make the console send a password reset email. Unfortunately for you, it’s going to the NSA and not you.
