Logic Masters Deutschland e.V.

LMDemasi has requested "approachable doppelgängers" for this week's Setting Saturday prompt as hosted by Scojo. This came out a little too difficult, but I'm allergic to adding unnecessary clues, so I made another puzzle to be my actual submission for the prompt (to be published tomorrow evening).

Many thanks to LMDemasi himself, as well as and aqjhs and IkeManga for testing.



DOPPELGÄNGER:
• Fill each cell of the main grid such that every row, column and box contains a 0 and five different digits from 1-6;
• No two rows, no two columns and no two boxes may be missing the same digit;
• For each 0 in the grid, the digits missing in its row, column and box must be three different digits;
• Fill the external cells with the missing digit from the corresponding row, column or box.

LINES:
• Adjacent digits along a hollow orange line must have a difference of at least 4;
• Digits on a pink line must form a non-repeating consecutive set.
