How a case works

Every case unfolds like a comic strip, one panel at a time.

  1. In-game screen: a letter from a chocolatier asking Jack for help, and the three suspects

    Open the case

    A letter lands on Jack's desk: a theft, a deadline and a handful of suspects.

  2. In-game screen: a message written in symbols above a letter keyboard

    Crack the code

    Anonymous letters are written in symbols. Tap a symbol, pick its letter, and the message appears.

  3. In-game screen: a grid of coloured number tiles inside the safe puzzle

    Open the safe

    Pair numbers that match or add up to the target, until the safe gives up its secret.

  4. In-game screen: the clues found so far and the list of suspects

    Name the culprit

    Weigh the clues you found, rule out the suspects and point to the one who did it.
