5×5 Night 35

Rules

This board needs JavaScript to play. The rules and the worked steps on this page read without it.

Hint 1: where to look

One square in this courtyard would shine on every square its neighbour has left, leaving that courtyard nowhere to stand.

Look at the leaf courtyard that includes the square at row 1, column 2, and its neighbour, the indigo courtyard that includes the square at row 1, column 1.

Hint 2: the first forced move

A lantern at row 1, column 2 would shine on every square the neighbouring courtyard has left, so that courtyard would have nowhere to stand — row 1, column 2 is out.

Clear the board?

Every lantern and pencil mark comes off and the clock goes back to zero.

The four rules

  1. Every courtyard gets exactly one lantern.
  2. A lantern lights its own square and shines along its row and column until a wall stops it. A courtyard edge does not stop light, and a lantern set on a lit square is dazzled, which is never allowed.
  3. No lantern may shine on another lantern.
  4. Every open square must end up lit.
