 Posted: Wed Sep 28, 2005 4:24 pm Post subject: How to reinstate a deleted candidate |
 |
|
| I find the Simple Sudoku program very useful, particularly when solving Killer Su Doku puzzles. However, I sometime inadvertently remove a possible candidate from a cell and discover later that I need to re-instate it. Is it possible to do so without going through multiple 'Un-Do' steps and, thereby, losing the progress to date? |

No, it's not possible except by using undo. (The danger in reinstating a candidate without undoing is that subsequent actions may also have been premised on that exclusion mistake.) |
