Continued self promotion without participating in the forum (ie ignoring the questions asked), and appearing to lie about your identity (presumably you are the man in the video, as you originally stated and then edited out) is likely to result in you account being banned.

Here is something of medium difficulty:

Code: Select all

1.736.2.......9...9..1..5.......8.1.6.1...9.2.4.9.......2..3..5...4.......8.714.6

And if you want a real challenge, try the Easter Monster:

Code: Select all

1.......2.9.4...5...6...7...5.9.3.......7.......85..4.7.....6...3...9.8...2.....1

But a video like the previous one doesn't prove anything. As presented in the video, the puzzle could easily have been solved with a program in advance and the solution memorized.

i dont understand ur codes, why not use the previous format

The format simply gives the clues for each of the cells from 1 through 81, numbered from left to right, top to bottom. Dots represent cells with no clue given. Here's the first of the puzzles Jason posted:

Code: Select all

 *-----------*
 |1.7|36.|2..|
 |...|..9|...|
 |9..|1..|5..|
 |---+---+---|
 |...|..8|.1.|
 |6.1|...|9.2|
 |.4.|9..|...|
 |---+---+---|
 |..2|..3|..5|
 |...|4..|...|
 |..8|.71|4.6|

I have solved ur puzzle, however it will take me about 10 minutes to complete it with eyes closed.

When you post a reply, below the area where you type in your reply, there are two tabs (Options and Upload attachment). If you pick the second tab (Upload attachment) it will allow you to attach a picture. However, the maximum size (in bytes) of the picture is fairly limited. In most cases you will need to reduce the image file size before uploading.

1. A new Sudoku solving technique allows for sudoku puzzles to be solved even without looking at the game board as demonstrated in this video.....

2. Give the guy some credit, he's doing the solving in his brain.

3. There are many ways to solve a sudoku puzzle, this is very likely a new technique. i love what he does and i will like to learn his technique.

Now that basscom4life has told us he is the solver, all this is clearly flim flam. It's not the puzzle being solved blindfolded in the video but the solution being recalled.

For the puzzle shown this isn't difficult
123 879 654
456 213 987
789 546 321

564 321 798
897 654 132
231 987 465

978 465 213
312 798 546
645 132 879
Note that the same triplets of digits occupy the rows in the boxes and likewise in the columns. It is a version of the 'Most Canonical' Sudoku grid where the digits follow a 'rope' pattern in Braid Analysis terminology. When 'braid' patterns exist two digits repeat together in one diagonal direction and the third digit repeats in the other diagonal direction. By memorising these patterns across and down the grid the contents of any cell can be worked out mentally.

Braid Analysis alone will only solve the simplest of puzzles though so it's not a complete solving technique.

@Bird, i clearly understand your analysis but i bet you even the smartest and sharpest memories cannot randomly provide those solutions by memorizing those patterns and recalling them in about 10 minutes like i have done. I challenge you to give it a try.

If i can write a code from a sudoku puzzle grid and use that code to solve it, isnt that a solving technique?

If you can write the code without first solving the puzzle, yes. Otherwise it's just a technique to recall the solution you already have. Also, if you say that you're solving the puzzle blindfolded, then you would have to derive the codes blindfolded after first memorizing the clues.
