Logic Masters Deutschland e.V.

Inspired by XeonRisq new constraint Delta Sums. I come up with Delta X-Sums, but with new twist of all pairs have unique differences.

Rules:

Normal sudoku rules apply.

Diagonal: Digits along blue diagonal may not repeat.

Difference Pairs: Digits separated by a white dot must have the difference given.

Unique Delta X-Sums: Clues outside the grid indicate the sum of the differences between each pair of adjacent digits in the first X digits in the corresponding direction, where X is the digit placed in the first cell in that direction. All pairs of adjacent digits in the sums must have unique differences.
