Cross Purposes (Quad Sums Killer Anti-King)

(Eingestellt am 6. Juni 2022, 02:42 Uhr von tallcat)

Was inspired by Udukos' brilliant 'Quad Sums Sudoku' and Grkles 'Quandary' to set a puzzle with the Quad Sums constraint. Hope you enjoy, and let me know what you think!

Normal Sudoku rules apply

Quad Sums: For each set of four cells touched by the same circle, the sum of three of the cells must equal the fourth cell. Not all circles have been given.

Anti-King: Cells a king's move apart in chess may not contain the same digit.

Killer: Digits in cages must sum to the given total.



Can be played online at f-puzzles or CTC

Lösungscode: Row 2 (left to right) followed by column 8 (top to bottom). 18 digits, no spaces.

Cool break-in, with clever interactions between the very sparse clues in the grid. Thanks !

Absolutely fabulous puzzle, from the beautiful opening sequence to the nice interactions later on, that quad sum in box 1 is really funky there :)
