Ruud, thanks for the daily Jigsaws! I thought that the difficulty of the Killers and the Jigsaws over at sudoku.org.uk is just right for me, but as a very lazy person, I find it a big hassle when trying to input their puzzles into SumoCue... :P Ruud, how is it that I can post to the Daily Jigsaw for...

Ruud's ALS-XZ is so big.

There is a smaller ALS-XZ, actually a Type 2 WXYZ-Wing. The cells involved are r2c8, r2c2, r3c1, r3c2, leading to r2c3<>3.

1) Load a puzzle. 2) Turn on pencilmarks (m). 3) While holding the CTRL button, click on the 1st square, 2nd square, ... 4) With the CTRL button still down, right click on the last square. Nothing happens. 5) Release the CTRL button. 6) Right click on the last square. The Place/Enable/Disable panel ...

My solver solves it with a lot of singles, one pointing pair and one BUG+1. Does not look anything like nightmare standard...

Have you noticed how his letters are arranged? Some of these letters might ring a bell to people who have taken a particular school subject...

Nice little puzzle there.

According to my own solver, after the puzzle is converted to digits, it is solvable using the "easy" techniques plus one UR and one ER.

Many thanks for making fixes so quickly. Bug 1: Load any valid sudoku. Holding the Ctrl key down all the time, click on one empty square, then the second empty square, then the third empty square, and then the third empty square again. Viola, some System.InvalidOperationException --> System.Argument...

This has happened in all SudoCue 2.0.0.x releases, up to and including 2.0.0.3, but I haven't got round in posting this until now. With almost locked sets and all 3D Medusa techniques enabled, staring from this: 006200000000004300800035000020000000000000731190000060004053002000700600050082100 By usi...

In the solving guide, you said that: It is also possible to form a naked triple with the surplus digits and 2 extra cells. Currently, I have no example available. I have an example that I use to test my own solver, but I forgot what is the starting position or where I took it from: .---------------....

For your reference, this is part of the algorithm I use to generate my own sudokus: generate_sudoku&#40;grid&#41; if grid has no solution // 1 return false if grid has exactly one solution // 2 return true select a random empty square s in grid for i = 1 to 9 // 3 assign square s in grid wit...

Hi Ruud, Really nice work there in SudoCue 2.0.0. However, I would still like to make two bug reports. Bug 1: Load any valid sudoku. Holding the Ctrl key down all the time, click on one empty square, then the second empty square, then the third empty square, and then the third empty square again. Vi...

Sounds like trial-and-error to me... I think guessing and trial-and-error are frowned by the sudoku community.

Hi Ruud, If you "Place All Singles" on an invalid sudoku with a square with no possible candidates (i.e. with no solution), then SudoCue complains with a NullReferenceException. An example is below. . . .|. . .|. . . . . .|. . .|9 . . 1 2 3|4 5 6|7 8 . -----+-----+----- . . .|. . .|. . . ....

Hi Ruud, Many thanks for your SudoCue program. I have used Angus Johnson's solver before coming to SudoCue, and I personally find that the difference between his solver and yours is that: your solver packs a lot more punch than his solver, but his solver is so much easier to use than yours. Two spec...
