Logic Masters Deutschland e.V.

The final Six-Loop puzzle I will be publishing, this time featuring a negative constraint and Fog of War.

This is the last puzzle of a trilogy, if you want to solve them in order of publication you can play the first one HERE, and the second one HERE.

Hope you enjoy!

Rules:

• Sudoku: Fill all rows, columns and marked 3x3 regions with the digits 1-9 without any repeats.
• Six Loop: Draw a 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. All circles are given.
• 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. All squares are given.
• Empty cells: Any cell not containing a square or a circle can not satisfy that rule. (For example: A 7 in an empty cell can not see 7 other loop cells if it is on the loop. If it's not on the loop, then it can not see 7 non-loop cells.)
• Fog of War: The grid is covered in fog. Entering a correct digit will clear the surrounding cells of fog, possibly revealing additional circles, squares or digits. No guessing is required.
