Logic Masters Deutschland e.V.

This is the second Six-Loop puzzle in a trio. If you haven't solved the first one, I suggest giving that one a try first.

This one ramps up the difficulty and has some more weird scanning, I hope you'll enjoy!

Rules:

• Sudoku: Fill all rows, columns and marked 3x3 regions with the digits 1-9 without any repeats.
• Six Loop: Draw a cell-wide loop in the grid, passing through the centers of orthogonally adjacent cells. The loop does not touch itself, not even diagonally. Any group of six adjacent cells along the loop must contain different digits.
• Circles: A cell containing a circle is part of the loop and indicate how many loop cells it sees vertically and horizontally (including itself). Non-loop cells blocks vision.
• Squares: A cell containing a square is not part of the loop and indicate how many non-loop cells it sees vertically and horizontally (including itself). Loop cells blocks vision.
