- A cyan or red Sum line must have sections with digits that sum to the same value, with sections divided by the 3x3 boxes.
- 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 given.
- A grey circle must contain an odd number, and a grey square must contain an even number

I'm misunderstanding the rules. Using the SudokuPad checker, I've gotten the numbers for Red and Cyan lines. But the 3 sections don't sum to equal each other. The 3x1 sums of the lines don't equal the outer 2x1 sums. May someone please help?
Answer - The five numbers on red/cyan lines in the centre are treated as one sum.

Good puzzle, nothing too difficult but those anti-sum deductions tend to hide in plain sight!

The 10 sum constant helped
