Nightwatch hints for September 25, 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 2, column 5.

Every square that could light row 6, column 8 lies in this courtyard, so its lantern is one of them — 8 other squares are out.

Squares this rules out:

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

7 lanterns, one in each courtyard:

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