Play missions, go in arena 39, and enter card codes to get clues. Get all 39!! ~James the Janus Check out this reusable card code! P3GJW7JEXP
There is no cheat codes in any game in the 39 clues.
I don't think anyone is generous enough to give you unreusable card codes but here's a reusable card code: P3WKFTCGXP
You can purchase card packs with codes for The 39 Clues. Examples of codes are: G69CTWHC9T, G69CKR3K9T, 223M6DTNX2.
The only card that has a reusable code is the Surveillance Camera card (card #1) that comes with The 39 Clues Book 1: The Maze of Bones. Other codes can only be used once. If the card code has already been entered in your gallery or another player's gallery, it won't work for your gallery.
They are not reusable. Buy codes on eBay if you really want them. ~James the Janus Check out this reusable card code! P3GJW7JEXP actually here's one: P4X363G9XP
this is a card that is reusable... P2W7RRJ4XP share it with ur 39 clues friends!
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.
