Nightwatch hints for October 11, 2026

Every square that could light one of these dark squares lies inside this one courtyard, so its lantern is one of them — the rest of the courtyard is out.

Look at the leaf courtyard that includes the square at row 5, column 1.

Every square that could light row 9, column 3 lies in this courtyard, so its lantern is one of them — 12 other squares are out.

Squares this rules out:

• row 5, column 1
• row 6, column 1
• row 7, column 1
• row 7, column 2
• row 7, column 5
• row 7, column 6
• row 8, column 1
• row 8, column 2
• row 8, column 4
• row 8, column 5
• row 8, column 6
• row 8, column 7

1. row 1, column 8
2. row 2, column 5
3. row 3, column 3
