To scramble the sudoku board, I designed an algorithm to randomly
mix the numbers from a preset orientation.
In the sketches of sudoku boards
below, each letter can be swapped with other variants of itself — ie columns A₀ and
A₂ or F₀ and F₁,
or rows M₁ and M₂ or O₀ and O₂ could be swapped within sudoku's rules.

Below are the average number of spaces per section of a sudoku board
(each of the 3 horizontal sections & each
of the 6 cube sections) for each puzzle
difficulty of easy, medium, hard, and expert: as per a sudoku app on my phone.
