Now that Ruud no longer appears to be involved with supporting or upgrading Sudocue, I have developed a similar solver (admitedly with less features at the moment) that I plan to keep supporting. It is freeware.

SudokuPlus is a combination of a solver, helper and generator

It supports a variety of solving methods (see below), full undo/redo, multiple input methods. The software generates puzzles to a chosen difficulty level, and can rate puzzles (individually or in a batch) and show solving methods required. You can optimise existing puzzles, get solving hints or access an interactive solving path (e.g. steps through all steps required to solve a puzzle with explanation of techniques). You can also elect to solve easy, hard or moderate steps. It provides support for manual input of games (e.g from newspapers) and allows you to solve puzzles manually with a variety of methods for inputting values and adding/removing candidates. It can also check manual moves for consistency/accuracy.

Solving methods include:
    naked + hidden singles
    locked candidates (types 1 and 2)
    pairs, triples and quads (naked and hidden)
    x-wing, swordfish and jellyfish
    XY-wing + XYZ wing
    skyscraper
    two stringed kite
    colouring (colour wrap and colour trap)
    BUG+1
    Brute force
Current version is v1.1. This addresses a minor issue which incorrectly asked for the Visual Basic Powerpack to be installed, and an instance where invalid puzzles (e.g. with duplicate values in a row, column or subgrid were not always properly detected).

Feedback, suggestions etc welcome. More information and download is at https://sites.google.com/site/sudokuplus.

Could you possibly elaborate on what techniques are incorporated.

With so many solvers outh there at the moment .... A more deatailed description might help it stand out.

hi garthd

i notice that you've responded to tarek's request by editing your original post

this works fine, except that the edit does not flag the Topic as updated -- thus tarek would have no reason to look here and wouldn't know that you've responded. (well now he will, as my post will flag this as updated.)

Version 1.2 is now available at https://sites.google.com/site/sudokuplus. This fixes an issue with background generation of puzzles slowing down the program

Happy new year! Version 1.3 of SudokuPlus!now available. This speeds up background generation of puzzles, also allows different types of symmetrical puzzles to be generated, plus some minor bugs squashed. Some little changes to the menus - user options are now all grouped in one area, and a new option has been added to highlight where individual candidates can be placed. Manual input of puzzles has been improved, plus displays info (no of clues and symmetry) of puzzles.
