Hello everyone, I'm asking for help about the naked triplet technique. I search for a solution with the techniques and the website wiki sudoku solver put the path solver. It first used the naked triplet and for the row E, I already found it but I don't understand how it found out for the J row where the numbers 3,8,9 can only be in case J2,J4,J5 because for me 8 can be in J1, 8 and 9 in J6 and 3 and 9 can be in J9. Is there something I don't get it about the technique ?
Thank you
