Card Packs are products dispersed for the 39 Clues that include sixteen cards inside
of them. Cards that are included in them will or will not help an agent get all 39 Clues, but by getting the cards inside of them, you may complete a Card Combo and receive a Clue. The cards that are in them are random, and so it is possible to get doubles or more. However in the Cahills vs. Vespers Series, the card packs have sixteen set cards.

Each card pack goes with certain books, so the first one goes with The Maze of Bones, One False Note, and The Sword Thief. Each pack also include a small booklet that includes information on characters, and various codes and ciphers.


There are currently four card packs for series one: Card Pack 1: Secrets and Sabotage, Card Pack 2: Branch vs. Branch, Card Pack 3: The Rise of the Madrigals, Card Pack 4: End Game/The Ultimate Card Pack And two for series two: and Card Pack 1: The Marco Polo Heist, and Card Pack 2: The Magellan Heist.
