Rules

  1. Draw lines through cells to make a single loop.
  2. The loop goes through the centers of cells horizontally or vertically. The loop never crosses itself, branches off, or goes through the same cell twice.
  3. The loop must go through all the cells with white circles. In each area enclosed by bold lines, the loop must either go straight through all the white circles or make a right-angled turn in all the white circles in the area.
  4. The loop must not go through the cells with black circles.
