Minor Pieces

(Eingestellt am 13. Februar 2024, 20:21 Uhr von gdc)

This is a follow-up puzzle to Chess Lines, which turned out to be much harder than I anticipated. Now I tried to tune down the difficulty by only using the "minor pieces" ( knights and bishops) and have clearer signposting for the opening.Tthanks to the CtC fan discord for testing. Hope you enjoy!

  • Normal Sudoku rules apply.
  • The blue cell in the middle contains an even digit.
  • Adjacent digits on a line must form a valid chess move by the indicated piece on a 3x3 numpad.
    • For example, a 1 on a knight () line may only have the numbers 6 and 8 next to it so 6-1-8-1 would be valid. An example of a valid bishop () line would be 1-9-5-3.
  • Digits separated by a black dot are in a 1:2 ratio. Digits separated by a white dot are consecutive. Not all dots are given.

Examples

Here are illustrations of the possible neighbors on a bishop () and knight () line. A 5 on a bishop () line can connect to every other odd digit. 1 and 9 can also be next to each other on a bishop () line since bishops () can move multiple squares along a diagonal. A 2 on a bishop () line can connect to 4 or 6. 5 can never be on a knight () line and a knight () always has exactly 2 possible neighbors on a line. A longer run for a knight () line would be 1-8-3-4-9-2-7-6-1.

Lösungscode: Column 5, top to bottom (9 digits)

I really enjoyed your first chess lines puzzle and this one was even better. Just beautiful.

wow gdc, that was fabulous! surprisingly approachable and cool logic given what looks like a tricky ruleset.

I did a video solve on my channel, including a hilariously overcomplicated last step that I realised later wasn't needed :P

I can only assume: at first I was staring at the grid understanding nothing at all. Then suddenly I had my „Aha!“-moment, and could follow the solution path which turned out very smooth. Thank you so much for sharing this wonderful puzzle.

I love the dawning realization that we've been given a lot more information than it might seem at first blush, and how smoothly everything flows once you figure out what *kind* of puzzle it is. Absolutely lovely!

This was an amazing puzzle.

The journey from "I don't even understand the rules" to the "this makes such a perfect sense" was just something you don't get too often.

Thank you gdc for setting this one!

Quite "Schach"-ing just how well this rule set works :)

Had an absolute blast solving this one. Love the ruleset!

This is a great introduction to a surprisingly interesting ruleset! will definitely be trying Chess Lines next!

Like @Jreg I was utterly stumped starting out, and I was really surprised by how constrained those lines are. And then I was really surprised at how obvious those constraints are if I think about them for a second. Nice puzzle, thanks @gdc!

Definitely more approachable than your previous one, very satisfying and smooth to solve, again a brilliant construction!

This seemed so very confusing at the beginning but once I discovered the P-word thing (trying not to spoil but if you know you know), it was suddenly very straightforward and enjoyable.

Thank you for the puzzle and the example! This was my first sudoku with this rule and the example really helped me :)
