As either bonus or warmup, a selection of smaller puzzles using the same line type is offered at the bottom of the page dopplperschg
RULES
DOPPELGANGER
– Every row, column, and box contains the digit 0 always, as well as eight out of the nine digits from 1 to 9 (ie, it's missing one digit that is not 0)
– No two row, no two column, and no two box may be missing the same digit
– For each 0 in the grid, the digits missing in its row, its column, and its box must be three different digits, yet zeros always have a null value (ie, zero)
ZIPPER LINES
– Digits an equal distance from the (dotted) center of a lavender line must sum to the digit in the middle of that line
Named after this swell fella:

Very happy to see your retirement from amazing sudoku publications was so short lived! Half way through when marking some doubles, triples, and quadruples, I suddenly realized a particular prime digit was missing from a particular box. Everything fell into place nicely from there. Especially liked one particular sum fully utilizing your favorite ruleset! Counting on you for more!

Thank you so much for the solve and kind words (and getting this one rated :D)! Indeed, this thing brought me back from 'retirement', although I have to say that it was, shall I say, not easy to set, and it immediately brought me back to that same point of exhaustion that had made me stop haha...
But yep, I'm still setting over on Discord, having moved to another old love, the Still Life ruleset (which I think I remember you being already familiar with), with the ultimate mission of getting Sktx's last non-rated Still Life an official red rating! So if you're interested in joining that mission, the puzzle is 'Living on the Diagonal' -- according to Sktx, it's a 3/5, but I say it's closer to a 4/5. If you're interested, the link is:

In any case, thanks for the continued support so far, and good luck on your own project -- looking forward to the finished product! :-)

A pleasure to test solve this for you - another monstrous puzzle with plenty of beautiful logical ‘aha’ moments. I knew from the break-in this was going to be a fun one (and it was!)

Well, thank you so much once again for accepting to test it, I knew full well it was no small request, but also that you'd be up to it, for being such a great solver of these 'Doppelganger' puzzles and provider of useful feedbacks :D So thanks again, I'm very pleased that you enjoyed that ride!
