Juggling with the Twins (Partial Killer)
(Published on 2. October 2020, 02:00 by SudokuExplorer)
Normal sudoku rules apply.
On a twin line, every digit occurs exactly twice.
The grey and blue lines are twin lines.
In a killer cage, no digit repeats and its cage sum is given at the top-left corner.
Anti-clockwise from the bottom-right, the cage sums are 11, 11, 28, 18, 12, 12, 29 and 19.
Moreover, there are some inequality signs between certain adjacent cells (at the top and in an 11-cage).
You can try this on Penpa+ or F-Puzzles. Good luck and enjoy the show!
Watch from time 15:30 mins to 23:15 mins of CTC video
Solution code: Enter the first and last rows (left to right)

Cool puzzle! Twin lines interacted beautifully with the cages. Had fun coloring afterwards too.

@TimE I'm glad you enjoyed it. :-)
And yes, I was very much inspired by the logic in Mitchell Lee's sudoku.

Wow! Loved the opening logic, and had fun colouring later.
Thankfully I saw a recent solve by Simon on CTC which uses a similar trick. Thanks so much for making this one :-D

Anti-clockwise from the bottom right, surely?
