Solve with Sudokupad
After you have solved it, click here here to see the picture without numbers.

Warning: There are two independent blue sumlines that add up to different numbers.
• Normal Sudoku rules apply.
• Digits along a blue line create a sumline where the sum of digits on a line within a particular 3x3 box must be the same for all the boxes the line passes through.
• Adjacent digits along a green German whisper line must have a difference of at least 5.
• Digits along a light orange parity line must alternate between odd and even.
• Digits along each grey thermometer must increase starting from the bulb end.
• The digits along each arrow must sum to the digit in the circled cell.
• Digits along diagonals pointed to by arrows outside the grid must sum to the number listed.
• A black dot between cells indicates cell values with a 2:1 ratio.
• A white dot between cells indicates cells with consecutive values.
• Not all dots are shown.
• A V between two cells means they add up to 5.
• An X between two cells means they add up to 10.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
