Logic Masters Deutschland e.V.

This constraint was invented by Gene for the 2nd round of Speed Setting Competition. I thought it was awesome idea and decided to make a new puzzle with it. Very happy with the result and hope you enjoy the puzzle!

Rules:

Normal sudoku rules apply.

Molecules: Some cells are defined as electrons. All cells containing digits from 1-5 are electrons, while cells containing digits from 6-9 may or may not be electrons. The electron cells inside each atom (circle) must sum to 8. Electron cells within multiple atom circles count towards all totals.

German Whispers: Adjacent digits along a green line must have a difference of at least 5.

Renban: Digits on a purple line form a set of consecutive, non-repeating digits in any order.
