In the Sudoku GP Estonian round , I am not clear with the rules of Unicorn sudoku. Is my interpretation right when I translate "Chess Knights placed in cells with number 9, must attack only different numbers" to all the digits that are a knight's step away from the digit 9 are different.
I did not try the example yet
I did not try the example yet, but this is how I understood the rules and it seems coherent with the solution. I agree that the formulation is not perfectly clear.
Unicorn
Yes, all the digits which are knight step away from a 9 must be different.
I'm not clear what "different
I'm not clear what "different numbers" are.
All of the digits that are a knight step away must be different numbers?
1, 2, 3, 4, 5, 6, 7 and 9 would be different numbers.
And must they also be not 9?
yes, 1,2,3,4,5,6,7 and 9 are
yes, 1,2,3,4,5,6,7 and 9 are different numbers.
If your question is, if one of the numbers can be 9, then the answer is yes. One of the numbers can be a 9.
I hope I got the question right. If not then please make another post.
Yes, that answers my question
Yes, that answers my question. Thank you.
The example shows solutions with 1, 2, 3, 4, 5, 6, 7 and 8 as all the anti-knight possibilities;
I didn't see any with a 9 in the example.
In the example puzzle there
In the example puzzle there is 9 in R3C5 and R2C7. And they are a knight step away from each other.
