Say, What Do Little Killers Eat?
(Published on 25. July 2024, 20:18 by RockyRoer)
The Rules
- [Sudoku] Normal sudoku rules apply - fill every row, column and region with the digits from 1 to 9 once each.
- [Even] A cell containing a square must have an even digit.
- [Simultaneous Outside Clues] Clues outside of the grid, some of which must be deduced, are two-digit numbers that serve three functions simultaneously: Sandwich, Little Killer along one diagonal, and Look-and-Say along the other diagonal:
- [Sandwich]: the sum of the digits in the cells between 1 and 9 in that row
- [Little Killer]: The sum of numbers in all the cells along that diagonal. Numbers can repeat along the diagonal if sudoku rules allow.
- [Look and Say]: The first digit of the clue indicates the amount of times the second digit appears along those diagonals. E.g. 35 clue means that there are 3 fives along that diagonal.
E.g. The odd clue might be 15, which means along one diagonal, there must be exactly one five, along the other diagonal, the cells must add to 15, and row 2's sandwich sum is 15.
The Puzzle:
Solution code: Row 9 from left to right

Hi RockyRoer, I was wondering how you can typ text (odd, even) in combination with arrows outside the grid on sudokupad? I normally use f-puzzles for construction, export them, and use https://marktekfan.github.io/sudokupad-penpa-import/ to convert it into a sudokupad puzzle. Thanks a lot!
reply: I use www.sudokomaker.app by sirxemic. It’s really condiment, even on mobile, and even creates links to Svens sudokupad directly. You can use cosmetic text and place it anywhere and any color/size. Check it out.
reply: Thanks a lot!!

Clarified that outside clues must be two-digit numbers.

Really nice logic, it was very fun to solve! Surprised to see 48 minutes on the clock, it felt like 15.
