And with that ends Decryptonite v3.0!
We deeply appreciate the efforts you guys put into these forty eight hours.
While we compile the final leaderboard, we would appreciate some feedback!

Official hint #1 for Level 7 :
Existentialism, dear user, must not escape your attention,
If only you possessed, an answer engine!

Ten minutes to go. This is in no way, over yet.

Official hint #1 for Level 5 (Five minutes before time):
The kind gentleman in question is Benny,
hours, dear users, you don't have that many.

Official hint #1 for Level Five will be revealed at 7pm; five hours before the hunt ends.

Many users have cracked the level since the revelation of official hint #2 for Level four and thus, there will be no more official hints for the level. What has been given, is, evidently, enough. Keep trying!

Official hint #2 for Level 4 :
To find the polyhedron in question,
"Think out of the BOX!", is our suggestion.

Official hint #1 for Level 0 :
You are the answer. But, how do we know you?

Owing to further mass requests, official hint #2 for level four will be released at 12 noon, exactly 12 hours before the hunt ends.

P.S : Understanding the hints will itself require a little bit of thinking. Don't expect straightforward hints for a level, which itself, is in no way straightforward.

Official Hint #1
Level 4 : U+002F U002F
