Rules

  1. Draw squares (□) in some of the white cells.
  2. A group of squares connected vertically and horizontally is called a “block” (including only one square). Each block must contain exactly one square placed on a pre-drawn arrow.
  3. Each arrow must pass through at least two blocks.
  4. The second and later blocks on the route of an arrow from start to end must progress by adding one square to the previous block without rotating or flipping.
