Ah excellent, thank you Angus, it's much easier to work with pencilmarks now!
I can't find a way to color pencilmarks, however? The only thing I can color is a whole cell. |

| When you are in SETUP state, if you put a wrong value in a cell there doesn't seem to be any way to undo the mistake. You have to reset and start over. |

You can click 0, space or delete to undo in setup (or even right click and clear). I guess I could enable undo in setup too. |

You can't color individual pencilmarks. I think that level of sophistication is way beyond what the vast majority would want out of this puzzle.

Cool, sorry I missed that. I was hitting backspace and canc - maybe you could enable the function on those keys as well.

I don't think I can agree with this.
Limiting coloring to a single number is artificial. Why should it be considered simpler to see when a number can only be in two places in a row, instead of a cell that can only contain two numbers?
It isn't simpler at all. On the contrary, in the former case you have to use filters to make it easier, while in the latter case you see it right on the main grid.
There is the same relation between the two that there is between pairs/triplets/quadruples and x-wing/swordfish/jellyfish.
A pattern like the XY-Wing is very simple, intuitive, and it works on multiple numbers. |

No, I'm not limiting coloring to single numbers, you can color any unassigned cell at any time (except when setting up) - there are no restrictions there.
I thought you were suggesting allowing each tiny pencilmark within a cell to have it's own color. That's what I meant as beyond the scope of the current design. |

That's what I was saying.
True, you can color each cell regardless of what pencilmarks it contains, but that is only useful if you are coloring a single number. It doesn't work otherwise.
Let's stick to xy-wing:
| Code: |
3 9 28 | 6 4578 1 | 257 24 457
28 1 6 | 578 4578 48 | 2357 249 34579
45 7 45 | 9 2 3 | 1 8 6
-------------------------+--------------------------+-------------------------
146789 346 13489 | 2 3789 5 | 378 149 3479
45789 2 34589 | 78 1 89 | 3578 6 34579
15789 35 13589 | 4 3789 6 | 23578 129 3579
-------------------------+--------------------------+-------------------------
24 8 7 | 3 6 24 | 9 5 1
12569 356 12359 | 15 59 29 | 4 7 8
1459 45 1459 | 158 4589 7 | 6 3 2 |
here one could color this way:
red the 2 in (2,1), the 4 in (7,1), the 2 in (7,6)
blue the 8 in (2,1), the 4 in (2,6),
and at this point notice that the 2 in (7,6), whch was about to be colored blue, is already red - so it must be true.
I completely understand that this would be a change outside the scope of the current interface. But I don't agree that it wouldn't be useful or desirable  |

OK. I'll put it on the wish list, but don't hold your breath  .
Anyhow, I've just release version 3.5, so it's out of beta testing. Thanks again Nick for the feedback.

Bug report.
Start a new puzzle. Select a cell with only one candidate. Note the count of remaining cells in the status bar. Press enter.
The big number is put into the cell, but the count of cells to go is not updated. Also, Undo is not available. |

Hi Nick.
Yes, it's definitely a bug. I'll fix and update shortly. Many thanks.

Bug report.
If you color a cell, then put a big number into it, the context menu only shows "undo", not giving the option to remove the color from the cell. |

Thanks again Nick. I've fixed that ready for the next release which will be out 'real soon now'. (Colouring will be properly disabled for cells with an assigned value.) |

Hi Angus,
Here's a bug report for v3.5u that I noticed whilst checking just how hard the Pappocom generated 'V.Hard' levels were using your software.
If you enter the following grid into simple_sudoku and try to solve it from the start you end up with an 'insoluble' error message.
| Code: |
14.|...|..9
6..|..8|5..
...|5.2|6..
-----------
.91|...|..7
...|...|...
3..|...|48.
-----------
..8|7.6|...
..9|3..|..8
4..|...|.61
|
The reason is because of the middle block which erroneously allows 2 as a candidate.
Presumably the program logic failed to re-do the column check on column 6? If the '2' is eliminated from the central block then it becomes soluble.
HTH?
Edit:
It would appear that this bug only manifests itself when entered from 'Setup' mode! If you copy and paste the grid above then the 2 is eliminated as a candidate.
Further Edit:
Yep, definitely a setup bug. Here's a paste to clipboard of the same set up grid erroneously allowing '5' in the top centre block!
| Code: |
{1} {4} {2357} {56} {3567} {357} {2378} {237} {9}
{6} {237} {237} {149} {13479} {8} {5} {12347} {2347}
{789} {378} {37} {5} {134579} {2} {6} {1347} {347}
{2578} {9} {1} {2468} {2345678} {3457} {237} {2357} {23567}
{2578} {25678} {24567} {124689} {123456789} {134579} {12379} {123579} {23567}
{3} {2567} {2567} {1269} {125679} {1579} {4} {8} {2567}
{25} {1235} {8} {7} {12459} {6} {239} {23459} {2345}
{257} {12567} {9} {3} {1245} {145} {27} {2457} {8}
{4} {2357} {2357} {289} {2589} {59} {2379} {6} {1}

Also, I'd like to add my congrats and thanks for such a wonderful Suduko program. Excellent stuff. |

Hi Brian.
Thanks for the feedback.
I don't doubt that there's a bug there somewhere, I just can't duplicate it at the moment. I've tried both cutting and pasting and manually entering cells to setup this puzzle and each time it solves to the end without a hitch. I've tried entering the starting cells from top to bottom and bottom to top as well and either way I can't find this bug.
Are there specific steps in entering which you can give which'll replicate this bug? Anyhow, I'll have a closer look at the code later.
Angus
Edit: OK, I've now spotted the problem in the code. Will fix shortly. |
