Logic Masters Deutschland e.V.

Rules:

Place the digits 1-9 in every row, column and box.

Region Sum Lines: blue lines are split into segments by box borders. Segments on the same line sum to the same total. Different lines can have different totals. No lines overlap, but they do branch.

X/V: digits connected by an X sum to 10. Digits connected by a V sum to 5.

Kropki: digits connected by a white dot are consecutive.

Note: I made a previous version, but it had some difficulty spikes that I didn't like. This version is more streamlined and thus also a bit less difficult. Shout-out to the folks who completed the first version!

Love, Brigitte
