Lines: Draw two non-branching lines in the grid - one green and one blue - that connect the centres of cells. The lines must only move orthogonally (i.e. not diagonally). Neither line may touch itself, even diagonally. The two lines may, however, touch or cross each other, but only at discrete points (i.e.if the two lines meet in the centre of one cell they cannot continue in the same direction into the centre of their next cell). The green line must form a closed loop; and, the ends of the blue line may not be on any intersections with the green line. Projected Sums: Clues outside the grid give the sum of digits on lines along the indicated direction. Coloured clues count only the line of that colour. Black clues count digits on both lines. If both lines pass through a cell, that cell's digit only counts once in the projected sum. German Whispers: Along the green line adjacent digits must differ by at least 5. Modular Lines: Along the blue line, in every run of three cells, the three digits in those cells must each have a different remainder when divided by 3. Clones: The two cages are exact clones of each other. They contain the same digits in the same positions and they contain the same lines (including colour) in the same positions. Digits may repeat within the clone if otherwise allowed.
