Magic Spiral
(Eingestellt am 13. März 2024, 17:18 Uhr von Teal)
Rules
Place a magic square somewhere in the grid, i.e. a 3x3 box with no repeated digits, and in which each 3-cell row, column, and main diagonal sum to the same number. (a magic square can be in more than 1 Sudoku box at once).
Box borders divide the blue Region Sum line into segments with the same sum. If the line passes through a magic square, treat the magic square's borders as black borders and ignore all black borders inside the magic square. (black borders still count for normal Sudoku rules)
A digit in a circle indicates how many times that digit appears in a circle in the puzzle.
A white Kropki dot separates consecutive digits; a black Kropki dot separates digits in a 1:2 ratio.
Digits in a cage sum to the small clue in the top left.

Nice puzzle. But I was very confused at first. I think the second paragraph of the rules could be improved. It starts by referring to "box borders", but then calls everything else "black borders". I think it should say "...treat the magic square's borders as BOX borders and ignore all BOX borders inside the magic square". Every border in the puzzle (box and all row/column borders) are black. The box borders are what are pertinent to the blue line rules.

Excellent puzzle design, very creative! I didn't remember certain properties of magic squares, so I struggled for a while. Once I got that figured out, it was still tricky but more doable. Thanks for sharing it.

What an interesting idea and combination of constraints. Well done.
