Hi all,
Here is the pattern I already found:

Hi,

This puzzle needs soemthing more than a "five star constellation" can offer:

Starting from the 2 digits: 2 & 7 in r5c4 and following "double implication chains" you can get: 7 not in r2c4.

And starting from the 2 digits: 2 & 3 in r2c4, you could get: 3 not in r2c8.

And this is probable all, which is not much at all and of course not solving the puzzle. The final position that I got was:

Scorpio:

Have you got the original puzzle right? It has 81 solutions as it stands, so guesswork is needed at some stage.

The partials you and someone_somewhere developed occur in all 81.

Hi Scorpio,

This could be a good reason why I can't find a solution. Laughing

I can't check if there is a unique solution.
The techniques I am using are leading me to the solution or not.
They are NOT leading me to ONE of the solutions, if there are several solution. This is because I am not doing "try and error".

Still I have about 5 puzzles, which I strongly suppose that they have unique solutions, but I can't solve them with the techniques I am using.

Thank you, Scorpio.

see u,

what does the code mean

Hi Guest,

The "code" means the, so called, "Candidate Table".
For a certain puzzle position, you write for every cell what digits can fit in it.
Probable, you will need this, only for very hard and higher Sudoku's.
With a long enough training one can manage (in average) up to hard ones without making any notes of candidates.

Hope I could help you,

Guest, Code is just the tag used to prevent your post from getting formatted (so the columns stay lined up properly).
Putting [ code ] with no spaces creates that inset box with code: at the top and the [ /code ] stops it.

Place the numbers above the numbers. Use the process of elimation mothod. Remember nothing can be the same in each blue box and nothing can be the same vertical and horizontal.
