Diagonal Water

Easy Used by Smart Hint

Ships never touch, not even at a corner — every cell diagonally next to a ship cell is water.

How it works

  1. A ship cell is confirmed in the center.
  2. Ships never touch, not even at a corner — and no ship bends, so a ship's own continuation is always straight ahead, never diagonal.
  3. All four diagonal neighbors are water, no matter how long this ship turns out to be.
