sometimes the wording on specific challenges might be a bit ambiguous or just plain confusing. this is not the intention; while solving the challenge might be tricky, understanding the text should not be. if you have a problem, please mention it here and i'll try to clarify the wording.

thanks,

A lot of the crypto ones have stumped me. I tried many different cryptography and steganography decryption methods to find the answer to a few of the problems "Ave", "Telecran", "Listen To Me", and "Lucy in the sky with briolettes". (but no answer was found)

I am not sure what to do about "Anybody out there" either

In general, crypto challenges don't have, like some other challenges, a clear indication of what you're supposed to do. They all behave the same way, however: what's on the challenge page (text, image, sequence, whatever) can be decrypted into a short answer, or answer description (but be aware that this might not always be textual).
In a lot of the crypto challenges, the text of the challenge provides a hint about what to do. Sometimes the NAME of the challenge can also be a clue as to where to look for inspiration...

So far, we have verified that all those crypto challenges CAN be solved using resources available to anyone (you won't need to break into the NSA to use their special equipment) in a short amount of time. Some are definitely trickier than others, but that's hard to judge when you know the answer

Good luck.

"anybody out there?" might just be my favorite challenge... tho nobody has solved it yet. this is one for which no hints can be given without spoiling it. i really believe it's doable, but it will take some thought and experimentation. the name is not arbitrary.

good luck,

well i ll take all your advice on do my best guys.

Indeed, 'Anyboy Out There' is solvable... I just checked it.

I don't think i understand objective of mission 'Pi hates nines' Does it mean that sequence must be 1 million digits long ( ) or i don't get smth??

It is supposed to be the longest consecutive string of characters found in the first million digits of pi, that does not contain a 9.

thx
btw, you asked about telecran and some others... there are hints in the names, and don't forget about google

wow that one was stupid, thanks for the advice. I looked on google before but didnt find anything, looked again and guessed the answer first try. felt like guessing someones password!

I don't understand the question in 'Didactic Green'. "Your task here is to examine these bytes for their own meaning, and get the answer from there." What is the byte's "own meaning"? The hex code doesn't have any meaning at all to a human.

Actualy in this case it does ^^
The numbers you get should ring a bell

i'm a new member of this community,,i hope the advice...thank's a lot

It is not quite clear to me in which order the maze is stored in memory. I assume it is like this:

0: width (23)
1: height (23)
2: (0,0)
3: (1,0)
...
24: (22,0)
25: (0,1)
26: (1,1)
27: (2,1)
...

Right? And up is (0,+1) and down is (0,-1), left (-1,0), right (+1,0)?

that is right, hwb
