The clue was Tungsten (Wolfram). The codes are unique and on the cards that come in the book. They cannot be shared because they are only valid for one use.
i do have a code for book 2, one false note! :D code: 23X9N7R2X3 top book riddle code: Look to india :) hope tht helped :D
To add book clues, you have to enter the card code from the cards you get in the book.
Look To India
You have to have the book cards. go to the39clues.com and make an account if u don't have 1 or log in and go to my cards. click on add cards and then type the code that is found on the card. by entering only 1 code, you will have all 6 cards in your cards since all the codes on the 6 cards are the same.
There is nothing called a code book. The 39 clues cards have codes by which you unlock cards. If you mean Agent Card Code then you can get your agent card code in the agent card option in my cards. My agent card code is P2FHHNDHXP
anyways it is K292J76PT3
Get the IPhone app and finish the game or type in a book code or solve the book puzzle or do the mission or get the cards
You take one of the cards from that book and enter it in the cards area on the site. click on "add cards" and type in the code. it's the same with cardpacks.
this is a new card code from the book titled vespers rising the card code will give you 6 cards to unlock mission 11 the card code is KCXJTCK3T3
What you need to do is type in a code from Moshi Monsters Mash up cards and then look in your inventory and it should be there! Note the code is random so if you don't get the right code, buy more cards until you do.
The real code for the cards is: 273H7KXMX9
