"V" is for Vertical Addition
(Published on 10. February 2026, 21:08 by gincal)
THE RULES
• Normal 4X4 Sudoku rules apply: The grid must be filled with the numbers 1-4, such that every digit appears exactly once in every row, column, and box.
• Diagonals: Digits may not repeat along the positive diagonal.
• Kropki Dots: A black dot separates two cells with a 1:2 ratio between them. Not every dot is necessarily given.
• X/V Pairs: A "V" separates two cells which add up to 5. Not every "V" is necessarily given.
• Arrows: Digits along an arrow's path sum up to the digit in the circled cell.
Solution code: First row.

The first puzzle i can honestly claim was a speed run. took exactly 1:00 but could've been under but for some mouse fumbling. ;)

First puzzle I've ever solved in under 30 seconds! (00:28).

Very nice - 68 seconds for me to solve though I suspect that time could easily be halved.

Wow. At least three times more difficult than the first one. I can only fear where this is going to end...Keep them coming!
