When you unlock the puzzles for each book, you get a replicator card. A replicator card can be used to unlock a common or uncommon card. 3 replicator cards can be used to get a rare card..
they are cards that you can unlock clues and replicators for.
The contest for free The 39 Clues cards expired in 2011. To get cards now, you must purchase them.
It is possible to get all of the 39 clues in a day, but you would have to add a whole lot of cards, but currently as of June 1st, only 37 clues are available.
the books will only give you ten clues so the cards fill in the gaps along with the 39 clues website
a grate card code for the 39 clues is P32979TXXP
