Double Filtration
(Published on 2. February 2023, 19:28 by Jay Dyer)
Rules:
- Normal sudoku rules apply.
- Nine cells (one per row/column/box) are doublers, and have a value equal to double their digit. Each digit appears in exactly one doubler.
- The values of cells in a cage sum to the clue in the top left corner. Digits may not repeat in a cage (though values may repeat).
- In row N (for all N from 1 to 9), the values of cells in the pill (read from left to right) give the row and column number of the doubler with the digit N.
Solution code: Rows 1 and 6.

Not too difficult, and quite fun to solve for the most part (especially early-mid).

I solved this during its testing phase on the CTC discord in January and absolutely loved the logic behind each step and how much „Jay Dyer“-y it felt to me. (Which means elegantly and beautifully constructed)

Brutally crazy genius

This is stunningly good! Thank you very much, Jay Dyer!

Great puzzle! More approachable than expected (perhaps partly because the start is so well telegraphed).

This is a stunningly good puzzle which I originally solved on the CTC Discord testing stream. Definitely not easy, but just beautiful logic.

A bit of a brain melter but very clever setting. Thanks Jay

A beautiful break-in and nice flow of logic thereafter. Thanks a lot for sharing!

Very creative idea, brilliantly executed. Great puzzle!

I think this puzzle may be impossible due to the position of the pill in row 5.
