Note: The Green Trees are thermometers. There are 2 blue sumlines whose totals are different. There is only one palindrome line. It does not continue under the blue sum line.

• Normal Sudoku rules apply.
• Digits along each GREEN thermometer must increase starting from the bulb end.
• Digits along a grey palindrome line read the same forwards or backwards.
• Digits along the orange Dutch line must have a difference of at least 4.
• 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.
• Cells with a grey circle must be odd.
• 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.

Solution code: Enter the digits in the first row.

Sorry that the palindrome line was confusing. I could make the palindrome line thicker to make it clearer, but then the sudokupad url would change.

Clarified where palindrome line ends.

Forgive me if I'm wrong, but how are we to assume that the grey palindrome line stops at r3c3?

EDIT: It appears a rule has been added to make this clearer. This is a fantastic puzzle, and I hope our earlier confusion doesn't detract from how nice it flows.
