A Nice Knightly Snack
(Published on 10. April 2025, 08:32 by PhoenixAki)
This puzzle is part of my snackdoku series. Snackdokus are sudoku puzzles that are generally smaller (4x4 grid) and simpler to solve. If you are an experienced solver, you will likely be done in hardly 30 seconds to 1 minute. Good practice even if you are newer to the hobby!
Rules:
To increase accessibility to my puzzles, I include hints in my puzzle posts (see below) and also post solution videos which guide you through the hints on my YouTube channel. If you'd like to solve this in your own video, go ahead! But ideally, let me know here or via Discord (same username) if you do ^.^
Hint: The X-Sum clue is where to start. R1C1 can only be 1 number to allow the clue to work. After that, the anti-knight constraint will be your best friend.
- Normal 4x4 sudoku rules apply. Place the digits 1-4 in each row, column, and 2x2 box without repetition.
- Anti-Knight: Cells that are a knight's move apart (in chess) may not contain the same digit.
- Arrows: Digits on an arrow must sum to the digit placed in that arrow's circle.
- X-Sums: A number outside the grid gives the sum of the first N digits in that row or column, where N is the digit in the cell closest to the given clue.

Added hints after learning recently how to do that in HTML. Wish I knew this last week when I went over all my posts...oh well.

Updated post as part of an effort to improve consistency of rule phrasing and post layout across all my puzzles.
