Nightwatch hints for October 16, 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 magenta courtyard that includes the square at row 1, column 4.

Every square that could light row 1, column 7 lies in this courtyard, so its lantern is one of them — 8 other squares are out.

Squares this rules out:

• row 2, column 4
• row 2, column 8
• row 3, column 8
• row 4, column 8
• row 5, column 7
• row 5, column 8
• row 6, column 7
• row 6, column 8

8 lanterns, one in each courtyard:

1. row 1, column 7
2. row 2, column 6
3. row 3, column 2
4. row 5, column 5
5. row 6, column 1
6. row 7, column 8
