Draw one loop and shade black cells to match the arrow clues.
Controls
Draw a single closed loop through cell centres. Shade some empty cells black. Every cell that is neither on the loop nor an arrow clue must be black, and black cells cannot share an edge. An arrow clue counts the black cells in that row or column in the arrow’s direction.
