Box 7: The lounge has a green recliner which is a German Whisper line. Adjacent digits along the line must have a difference of at least 5. The person lying on the chair is represented by an arrow. Digits along the arrow must add up to the digit in the attached circle.

Box 8: The hall has a red carpet which are column indexers. The digit in the cell indicates which column contains the 5 in that row. Along the sides are red tapestries which are Parity lines. Digits along the line must alternate parity.

Box 9: The study has a small collection of instruments. The black dot separates digits in a 1:2 ratio. The white dot separates consecutive digits. The V separates digits that add to 5.
