(Published on 27. August 2024, 09:52 by bboom)
This puzzle is part of a series I'm making, exploring the odd anti-knight / even anti-bishop mechanic. Other puzzles in the series can be found here:
- First Practice (easy puzzle to try out the anti-bishop/anti-knight rule)
- Deranged scribbles or modern art?
- Knight and Bishops, dancing around dots
- Anti-Knight and Anti-Bishop Killer
- Bishops eat their sandwiches at 5:29
- Minimalist art or more deranged scribbles?
- Directionless Knights and Bishops
- Scribbled art in deranged colors
Puzzle rules:
- Normal sudoku rules apply.
- Odd anti-knight: Cells separated by a knight’s move in chess cannot have the same odd digit.
- Even anti-bishop: Cells separated by a bishop’s move in chess cannot have the same even digit.
- Killer: Digits in cages must sum to the number in the top-left corner and cannot repeat.
Solution code: Row 9 (9 digits, no spaces)

Excellent puzzle. The superior range of the Bishops surprised me. How can chess players insist the Knight is equal? Maybe the 9x9 grid makes the difference, and that if Chess is played on a 7x7 board then the knights would be stronger than the Bishops.

That was absolutely brutal. 120 minutes in total. I got badly stuck with 8 correct digits in the grid, until I realized some of my pencil markings had applied anti-knight logic to even numbers.

Nice! I don't think I used the 23 cage in my solve.
