For the most recent Setting Saturday, the required features were Quad Circles and some form of duality, where two common variant types were combined into one clue type. I think most of you will guess what items I combined for the Tien Dots!
----
Rules:
- Normal Sudoku rules apply.
- Quadruples - digits inside the large white circles must appear at least once in one of the surrounding four cells.
- Tien Dots - digits separated by an orange Tien dot must sum to 10, AND must also differ in value by at least 4. No negative constraint.
----
Puzzle:
Solution code: Row 9 digits, left to right

Very good. I thought I had hit a deadly pattern at the end but I missed a couple of digits in the quad clues that ended up resolving everything.

Thanks! Toward the very end was a deadly pattern. Resolved with bifurcation.

I liked solving it, but the Tien Dots are just an X that can't have 4 or 6. It doesn't use the Whispers rule in any real fashion to differentiate itself.

Love the Tien dot rule, made for some really fun logic to cruise through! A perfect 1 star!

Easy but not boring

Smooth and simple, a tasty snack.

This was pretty fun, but that Tien dot rule is really restrictive, which made it rather easy. Definitely 1/5.
>>>NSM here - that's entirely fair! Good thing I didn't make German 10 dots, I suppose.

A delight. A miniseries of this new dot ruleset would be greatly appreciated.
>>>NSM here - so glad you like it! I'll have to ponder other ways this could be applied.
