XVXV - Episode 3: Killing Eve

(Published on 24. April 2022, 16:56 by henrypijames)

  • Normal sudoku: Fill every row, column and marked 3×3 box with the digits 1 to 9 once each.
  • Classic Kropki: Cells connected by a black dot have a ratio of 1:2.
  • XVXV: Cells connected by a V sum to either 5 or 15; cells connected by a X sum to either 10 or 15.
  • No negative constraint: Not all possible X, V and dots are necessarily given.

This is the very first puzzle I’ve created! I’m immensely grateful to Cracking the Cryptic and Logic Masters Germany for introducing me into the world of variant sudoku; to all the people in this wonderful community who have encouraged me to dip my toes into puzzle creation; and most importantly, to @Raumplaner for taking me on as a newbie partner with an unknown and untested ruleset.

Solution code: Column 4 (top to bottom, 9 digits)

Such a fun solve! Also took a bit to wrap my head around the rules, but it all worked out super beautifully

2 1/4 stars I'd say, bordering on 2,5

>>>
LOL, though I only ever use fractions and never floating point (which gives an unwarranted illusion of accuracy - cf. AP guidelines on reporting polling results and other statistics).

~Ah I thought I'd covered the not specifically accurate by stating it was 'bordering' on 2,5, either way, nice puzzle Henry!

That was fun, I really liked the logic involving ambiguous XVs. Some deductions were tricky for me but it isn't too hard once I understood it, I was just being slow.

Love me some ambiguity! Awesome first puzzle and collaboration. Took me quite a while (probably too long) to uncover all the implications of this rule set... but I have emerged from the other side much stronger!

>>>
We'll see in subsequent puzzles if you have truly uncovered *all* the implications of this ruleset - Raumplaner is already working on the next episode featuring some logic not used so far. ;D

This is a very clever ruleset, and this puzzle taught me several ideas about how these constraints work in a really fun way. Congrats on your first puzzle!
