What’s the difficulty of the OpenSky Sudoku generator?
The difficulty level (“Easy”, “Medium”, “Hard”, “Very hard”) appears on the printed page along with a difficulty factor ranging between 0.01 and 1.00 (the higher the value, the more difficult the puzzle). I did not write the generator itself; it is part of the gnome-sudoku software, written by Thomas Mills Hinkle.

Is there an app that solves Sudoku the same way?
A solver app won’t solve a puzzle the same way when it’s rotated or flopped. It will even sometimes analyze it as a different difficulty rating even though it’s technically the same puzzle. However, Big Bad Sudoku Book has 10’s of 1000’s of seed puzzles in 5 difficulty levels, and multiple puzzle patterns types.
How many variations are there in a Sudoku puzzle?
That alone creates about 300,000 variations on each puzzle. Rotate the puzzle by 90, 180 or 270 degrees. That adds 4 more variations. Flop the puzzle horizontally, vertically, or both. That adds 4 more variations. Each seed puzzle therefore can create 5,806,080 variations. I’ve tested this in the field with real players.
What is the objective of the Sudoku puzzle?
A Sudoku game is number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called “boxes”, “blocks”, or “regions”) contain all of the digits from 1 to 9.
