Jack Decode is our cozy detective game for mobile: a brain game in the style of a classic clear-line comic book, where each case unfolds one panel at a time. Anonymous letters, coded messages, a locked safe and a room full of suspects: Jack needs a hand to crack the case, and that hand is yours.

A case, panel by panel

Every case reads like a comic strip. You move from one panel to the next, and each panel is a puzzle:

  • The cipher: tap a symbol, assign a letter and watch the message reveal itself.
  • The safe: pair matching or summing number tiles to reach the target.
  • The word search and the boss puzzle: the clues hide in plain sight, and every case has one last lock to pick.
  • The deduction: weigh the clues, rule out suspects and accuse the culprit.

Calm by design

Jack Decode plays offline. There is no account to create, no ads and no in-app purchases: you open a case and solve it at your own pace. The game is coming soon to Android and iOS, played in portrait, in English and French. In French, Jack goes by the name of Jacques Décode.
