The above lines are for a straight forward Samurai puzzle.

When I copy-paste it into Sudoku Solver, I then hit Solver/Step to highlight the pencil marks that can be cleared from the givens.

Please note Nonet 2 (r3c4), has a 7 immediately placed in the cell (big number). However, the cells in r3, c4, and nonet 2 that have 7 as a candidate are not shown in red to be eliminated when clicking on any cell.

Why is this? Why aren't they not automatically eliminated when the 7 in r3c4 is placed?

I have found other instances where Big Numbers are automatically placed where the pencil marks in affected cells are not adjusted for the big number placement.

Can someone please tell me what the solution is to this issue?

Thanks so much.

Regards,
George

Me not, sorry.
Have a good time with your solver.
There is a sudoku variant section in this forum.

I don't think SudokuSolver has an option to auto-update pencilmarks. Try Ruud's Clueless Helper which does (samurais and auto-update pencilmarks), it can be downloaded from here.

You can also try posting you r query on the SudokuSolver forum at http://www.rcbroughton.co.uk/sudoku/forum/index.php

As I recall (it's been a while), you have to explicitly tell the program to update pencil marks after you place a number in a cell. I vaguely recall a discussion with Richard about that, but I would have to go back to the SudokuSolver forum and find it to recall the details.

Hi enxio27. Glad that you are back. It is more than a year since your last post.

Thank you! It's great to be back! Hard to believe it's been a year, but it has gone by very quickly.
