Step by step

The order our solver finds. Each step uses only the clues and what the steps before it proved, and its heading links to the technique.

  1. Last cell left Every other cell is ruled out for Oscar, by his testimony or by a row or column already taken. Placed: Oscar: row 1, column 4 (Dining Room); Bruno: row 2, column 5 (Dining Room); Elena: row 6, column 6 (Library); Jonas: row 3, column 2 (Chapel).
  2. Room counting The victim, Quentin, cannot be in the highlighted cells: his room there could not hold exactly one other person. The cells meant: row 5, column 1.
  3. Room counting The victim, Quentin, was in the Chapel with exactly one other person, who is already there. Nobody else can be in that room. Placed: Clara: row 5, column 1 (Pantry); Quentin: row 4, column 3 (Chapel).
