Midstream, by James Sinclair
Normal sudoku rules apply, and all clues are standard.
Renban lines: purple lines contain a non-repeating set of consecutive digits in any order.
Quadruple circles: a digit inside a white circle must appear in at least one of the four cells surrounding that circle (if a digit repeats in the circle, it must appear twice).

Originally published in Artisanal Sudoku, Volume 202. I cross-post Artisanal Sudoku puzzles here from time to time, and they're usually among the tougher ones, because those tend to be my favorites (and also because I know how much folks around here like tough puzzles). But there are plenty of 1* puzzles in the newsletter too, so I thought I'd post this one as an example. Enjoy!

Easy one with some interesting deductions. And they are useful in advanced levels as well (that is what make them really interesting to know)

I loved how this puzzle just sort of falls into place once you break in. Also, the break in was fun but not too hard, which was exactly what I was looking for in a puzzle today. Thank!

Hard at first for me. Took about 45 minutes. I enjoyed the challenge, thank you!

I completed this one when it was in the newsletter, but I do love it when you post them here so they are in my statistics. I solve all of the puzzles in the newsletter every time…except that one with the series of really hard ones. I only solved one or two of those.

Solving this puzzle feels like travelling 1st class on a high speed train. Thanks

You have a genuine talent for finding new and beautiful pathways using simple constraints. It's a pleasure to receive the newsletter each Monday and to sit down with these puzzles over lunch!

First glance, I had no clue how to get started, but after scratching my head for a while the light dawned and the race began. Amazing symmetry throughout.

Very fun puzzle! It had a very interesting symmetry to it where with every move I made I had to make sure to do the same on the opposite side.
