Ten-Oh (10-Lines sudoku)
(Published on 21. May 2023, 18:31 by Qodec)
After zetamath's 10 Lines.
- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- 10-Lines: Each line consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap; every cell is part of exactly one group. Digits may repeat freely on lines and even within sums. (For example, 18173 would be a valid fill for a length 5 line, because we may divide it as 181 | 73.)

Good luck!
Solution code: Rows 2 and 8. I.e. the 9 digits in row 2 from left to right, followed by the 9 digits in row 8 from left to right, for example: 123456789123456789

The puzzle is full of "dead ends", I've use ABCD5EFGH to do algebraic sudoku (A+B=C+D=E+F=G+H=10) and later figure out what ABCDEFGH are. Looking r6c2-r7c3 line you might ignore the possibility of double 5 and enter a dead end. Also the diamond at bottomright if you know the sum of diamond is 10 rather than 20 and put 1234 into that diamond you'll go into another dead end.

Wow, what a tough puzzle! I really like the opening deduction and I think it's already pretty hard, but the puzzle still doesn't give up way until the end. I must've missed some more obvious way to proceed though because some of my deduction feels too bifurcation-ey to me.

I doubt I would see a 10 line puzzle that is more intricate than this one. What a consistently rewarding solve path with lots of cool (yet surprising) deductions!
[also help me, I'm craving for fried shrimps and doritos there lol]
