Nudge points you toward a useful lead. Explain shows the clues and reasoning, one step at a time. Reveal previews the next move. Your board changes only when you choose Apply this move. You can undo that move. Reopening a hint or reading its later stages does not use another hint.

Only when a general clue says so. Some cases state how many people occupy a room or a type of furniture. Read the general clues above the character cards. These counts include the victim. Without a general clue, a room may be empty.

Placed records your choice without checking it. Once everyone is placed, choose Check solution. Correct placements turn green and incorrect ones turn red. Labels and symbols also show the result. Editing the board clears this feedback so it always matches your current choices.

Choose Review solution to return to the completed board. Each person remains in the correct square. Tap a square to inspect its person, coordinate, and area. You cannot change the board during review. Use Replay to start a fresh attempt.
