Normal 6x6 sudoku rules apply.

Kropki: Cells separated by a white dot contain consecutive digits. Cells separated by a black dot contain digits where one is double the other.

Pi-Line: Hollow golden lines are separated into segments by golden dots. Each segment (when 'read' as a multi-digit number) is in a ratio of between 3 and 3.2 (inclusive) with all adjacent segments on its line. All segments are 'read' in the same direction along the line.

For example, 6-5-4-*-2-1-3 would be a valid line, as 654/213 = 3.07. However, 6-5-4-*-3-1-2 would not be a valid line, as 654/312 = 2.10.

Digits may repeat on a line if allowed by other rules.
