How a case works

  1. EXHIBIT A

    Read the statements

    “I was NEXT TO the LAMP, and I was NOT in the KITCHEN.”

    Nobody lies. Every statement is a piece of the puzzle.

  2. EXHIBIT B

    Place the suspects

    One suspect in every row. One in every column.

    Sudoku, on a crime scene: rule squares out, and the rest falls into place.

  3. EXHIBIT C

    Name the thief

    The thief is the only one ALONE WITH the treasure.

    No guessing, no luck. Just you, the clues and the culprit.
