Far far away, behind the word mountains, the countries Vokalia and
Consonantia, there live the blind texts. Separated they live in
Bookmarksgrove right at the coast of the Semantics, a large
language ocean.
A small river named Duden flows by their place and supplies it
with the necessary regelialia. It is a paradisematic treasure, in
which roasted parts of sentences fly into your mouth.
Even the allpowerful pointing has no control about the blind texts
it is an almost unorthographic life One day however a small line
of blind text by the name of Lorem Ipsum decided to leave for the
far World of Grammar.
In the Big Oxmox advised her not to do so, because there were
thousands of bad Commas, wild Question Marks and devious Semikoli,
but the Little Blind Text didn’t listen. She packed her seven
versalia, put her initial into the belt and made herself on the
way.
When she reached the first hills of the Italic Mountains, she had
a box back on the skyline of her hometown Bookmarksgrove, the
headline of Alphabet Village and the subline of her own road, the
Line Lane.

note: the last challenge was to open a box with a lock that had the code of the previous challenge. The box was filled with candies and it was sufficiently wrapped so bruteforcing it would have been difficult. In fact, a couple of kids tried to open it without the code but it's important to make this solution as hard as possible.

But I must explain to you how all number of this mistaken idea of
denouncing pleasure and praising pain was born and I will give you
a complete account of the system, and expound the actual teachings
of the great explorer of the truth, the master-builder of human
happiness.
No one rejects, dislikes, or avoids pleasure itself, because it is
pleasure, but because those who do not know how one-hundred-thirty
pursue pleasure rationally encounter consequences that are
extremely painful.
Nor again is there anyone who loves or pursues or desires to open
pain of itself, because it is pain, but because occasionally
circumstances occur in which toil and pain can procure him some
great pleasure.
The trivial example, which of us ever undertakes laborious
physical exercise, except to obtain some advantage from it?
But who has any right to find fault with a man who chooses box to
enjoy a pleasure that has no annoying consequences, or one who
avoids a pain that produces no resultant pleasure? On the other
hand, we denounce with righteous indignation and dislike men who
are so beguiled and demoralized by the charms of pleasure of the
moment, so blinded by desire, that they cannot foresee.

# Offline Challenges
Those are challenges that are made for children, there are two series. One easy
one for large groups and one hard one for smaller groups. The level of
difficulty is set on the need of the involvement of an adult to explain the
challenges.
Each challenge have an answer that is a hint for the next one.
Usually each challenge is given in an enveloppe. Especially for large groups, it
allows the organisators to see which group is where. On this serie, only the first
exercise is different for each group (so they don't cheat between groups).
The idea is that at the beginning or at the end of each session there is a small
explanation of simple ciphers such as the Ceasar cipher, Morse code... Usually
things that are inside the game which an aim to explain why people would use
encryption or hide their messages, why is it important...
