This is the first in what may become a series of puzzles with a constraint I call lucky charms. This is based on one of my all time favorite sugary breakfast cereals from the US.
This is the third in a series of puzzles with a constraint I call princesses. If you like this variant, feel free to check out the others. Ordinary sudoku rules apply.
This puzzle is very clearly inspired by Mitchell Lee's famous Miracle Sudoku and is a bit of low hanging fruit.
The rules are the same as the miracle sudoku rules: Cells separated by a King's move or a Knight's move cannot contain the same digit.
This is a follow up little killer version of my previous puzzle. And my very first puzzle with no given digits! Ordinary sudoku rules apply. In addition, the number in a box tells you the minimum diagonal distance between another of the same number.
The numbers in this puzzle have a constraint I call anti-princess Rules: Ordinary sudoku rules apply. In addition, the number in a box tells you the minimum diagonal distance between another of the same number.
Rules: This magenta box is a 4x4 magic square that has been tilted 45 degrees. This magic square must contain the numbers 1 through 16 exactly once and each row, column, and main diagonal of the magenta box must have the same sum.
Try it EITHER as King Sudoku (identical digits cannot be a chess king’s move apart) OR Queen Sudoku (9s cannot be a chess queen’s move apart) OR Knight Sudoku (identical digits cannot be a knight’s move apart)
This is the Goldilock's puzzle. It has 3 solutions. The first and easiest solution is found after placing a 1 in the central gray box. Placing a 2 in the box gives a moderately difficult solve.
