The Miracle is an anti-knight, anti-king, non-consecutive sudoku, which means that as well as normal Sudoku rules (that is, the numbers from 1 to 9 must appear only once in each row, column, and cage) the following rules also apply:

1. Anti-knight rules: no two squares that are a knight's move apart can have the same digit. (The knight's move is 2 along and 1 to the side, as in chess.)

2. Anti-king rules: no two squares that touch either horizontally, vertically or diagonally can have the same digit. (As in, no two squares a chess king can move between in a single move.)

3. Non-consecutive rules: no two squares that are horizontally or vertically adjacent can have consecutive numbers.

Each of these extra rules brings a new dimension to Sudoku and the result is an exquisite puzzle, which dazzles by starting with so little information - just two clues! -and yet has a unique solution. Hence it's name, the Miracle.

There is a video clip on the BBC (UK) about people flocking to a youtube channel (Cracking The Cryptic) to watch Mark Goodliffe and Simon Anthony solve sudokus for entertainment and relaxation.

That's cool, but I would remind people that we have already created puzzles with zero clues, and even less rules: Absolutely Clueless

We've done clueless Str8ts to death years ago. Here is an example. Paste the following link into your browser's URL box and up will pop a picture of the puzzle. is.gd/Clueless_Str8ts

There are no clues, only one hint : Cell F3 is not 3. The solution is quite easy.

You can find out the rules of Str8ts here.

The miracle is that they found easy to solve 2 clue puzzles.

I attempted generating puzzles of this variant. I had many symmetric 2 clue puzzles!
