Rules:

Pi = 3.14159 26535 89793 23846 26433 832795

• Place the digits 1-9 once each in every row, column, and 3x3 box.
• Kropki: A white dot connects consecutive digits. Not all possible dots are shown.
• Pi Path: There is a path in the grid that travels to adjacent cells, orthogonally and diagonally. The path will write out the digits of pi in order, as provided above (until the first occurrence of a zero). The path may not cross itself or occupy the same cell twice.
• German Whispers: On green lines, adjacent digits must differ by at least 5. All lines are part of the pi path.
• Cage: The sum of the digits in the cage equals the number of cells that the pi path visits in the outer perimeter of the 9x9 grid.
