Zipper++
(Eingestellt am 10. Januar 2024, 19:49 Uhr von RockyRoer)
The Rules:
- [Normal sudoku rules apply]: Fill every row, column and 3x3 box with the digits from 1 to 9 once each, with no repeats.
- [Incremental Zipper Lines] The lavender lines are variant of zipper lines. In regular zipper lines, each pair of digits coming out from the center digit on a line sums to the same thing. In this puzzle, the sums of each pair of digits coming out from the center increases by one.
- For an odd length line, if the center cell has a value x, the next pair out from the center add to x + 1, then x + 2, etc...
- eg. 12768 (7, 8, 9)...
- For an even length line, if the center pair adds to x, the next pair adds to x+1, then x+2, etc...
- e.g. 645798 (12, 13, 14...)
- For an odd length line, if the center cell has a value x, the next pair out from the center add to x + 1, then x + 2, etc...
The Puzzle:
Try it on CTC sudoku pad or Sirxemics Sudoku Maker

this ruleset is surprisingly intuitive and creates the weirdest goodliffs that I've seen in a long time. Love it!

This ruleset looks crazy at first blush, but turns out it is totally manageable, and also elegant!
