Here is a rare one
The death clue: p462nrgxp
I can not tell you that but I can give you a replicator card worth ten replicators so that you can replicate your own cards to get clues.
I don't think anyone is generous enough to give you unreusable card codes but here's a reusable card code: P3WKFTCGXP
it's technically impossible for me to give you all the card codes cuz someone might have added the codes already but i can give you my agent card code which can be added to your card collection Good luck in your hunt!! my code: P426X3CMXP
Since you have to buy the card, and the code can only be used once, I don't think anyone would give up their code to help you.
To get the exclusive walmart card you must type in g69ctwhc9t and to get the surviellence card you must enter 262p6xktx2
Go do all the missions. You can get about 13 clues from it. Otherwise, buy the card packs. Happy hunting =] P.S. Please add me to you allies: P33NHHKTXP i will give u the copper clue number 14 ok and if someone gives me the scoreboard code i will give more clues and their cards and if you have any more codes i will give more valuablee codes and cards thanks and ekats rule
You can start combining cards on the 39 clues after book four comes out. The "my cards" page will be up graded. The cards that you have already will combine automatically, just go to my clues and you will have new clues. To know if you have a card that can combine in the series two, look in the top left corner. If you see a key your card can combine with other cards with a key with the same symbol such As an alien or Africa. Ask more questions because I know the answers, but I will not give away card codes or puzzle answers.
There is no such code, however, by buying cards and completing missions you can get clues. I would post some ultra-rare card codes, but I don't have any that I haven't already used. My top tip is to save your card replicators, because they can be used for those hard-to-find ultra-rare cards. You can give the codes to this site because the codes are reusable.
All you have to do is get all the 39 clues books at the library, then go to the website and it will give you a list of all the books, you chose a book then it will ask you to go to a chapter in the book and find a word, after you're done they give you the cards.
I would tell you but not all the clues are out yet. There are 10 clues from all the books (only 6 books are out) and 10 clues from online missions (not all are out yet) and certain cards once you enter them give you clues (all so far are 4 rarity) and card combos (not all card are out yet) JANUS
idk why people give out card codes. i mean, you are just giving out other people a chance to win the $100,000 reward. alright first of all. the codes that they give out are already used. second of all most of them that they give out are reusable. third of all you can only win the money if you get the most points in the world in the games. (they have a winner every episode though.)
You need to buy the card itself. Nobody will just give it away. The websites that say 'free neocash codes' are usually scams. Glad I could help.
