This challenge is about protecting the most flexible part of a block board.

Puzzle prompt

You can place a three-block line along an open edge or across the middle of an empty 5x5 board.

Which placement usually keeps more options open for the next piece?

Hint

The center can connect shapes arriving from several directions. An edge has fewer directions to protect.

Answer

Place the line along the edge. This keeps the center open and leaves a larger connected area for future pieces.
