here to see the picture without numbers.
Note:
The trees are light green thermometers.
The X is an olive green German whisperline.
The parity line is light orange.
• Normal Sudoku rules apply.
• Digits along each light green thermometer must increase starting from the bulb end.
• Adjacent digits along an olive 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 a grey palindrome line read the same forwards or backwards.
• 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.
• The digits along each arrow must sum to the digit in the circled cell.
• Cells with a filled circle must be odd.
• Cells with a filled square must be even.
• Digits along diagonals pointed to by arrows outside the grid must sum to the number listed.
• 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.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
Solution code: Enter digits in the third row.

You almost had me guessing regarding the palindrome but i plugged away and found the right answer at that point.

Very nice but maybe nearer 2 stars than 1 star?

Got wedged 2/3rds of the way through thanks to a somewhat subtle clue, nobody’s fault but mine. Very nice puzzle.
