Sum In Tent
The brief
Sudoku: Put the digits 1 to 9 once each into every row, column & 3 by 3 box.
Region Sum lines: The box borders divide each hollow blue line into sections which must have the same sum. This sum may be different for different lines.
Each Region Sum line is also a German Whispers line, a Parity line, or both.
German Whispers lines: Each pair of cells along the line must contain digits that are at least 5 apart.
Parity lines: Each pair of cells along the line must consist of an odd and an even digit.
The solver must determine which line is which.
