Micro Folded Chess Problem
(Published on 7. March 2025, 00:04 by Gnubeutel)
Normal 4x4 Sudoku rules apply. Place the digits 1-4 in every row, column and box exactly once.
Chess: cells with chess symbols have to see at least one other cell of the same value by moving in the way their chess piece would. I.e. a knight must see its value again two steps in one direction and one step to the side, and a bishop sees itself by moving diagonally.
Fold-In: The dashed red lines are folded onto each other so that column 1 and 4 form a secondary grid. In this grid all rules apply, except that regions and rows do not need to have all of the digits (it's a 2x4 grid). Columns 2 and 3 are ignored for this grid.
Kropki Dots: cells separated by a black dot are in a 1:2 ratio, cells separated by a white dot are consecutive. Not all possible dots are given.

Simple, fun, a good introduction to the rules.

Neat. I’d like to see a 9x9 version of this ruleset.

You're absolutely right. Good thing it's only a 4x4, so some people were able to solve it on paper.
