Isanaki 2.6b
Isanaki 2.6b is a free Multilingual Sudoku and Wordoku Game, a Sudoku Board Generator, Solver and Printer designed for Windows 2K and XP. In this release, using the brute-force technique, it solves all boards (to the best of my knowledge) and, using logical deduction, it solves most of the hard Sudoku boards.

The version 2.6b supports English, French, Spanish and Dutch languages... More to come according to request !!!
The goal of this game is to fill the board so that each number appears only once in any row, column and block. Isanaki 2.6b is designed to help you finding the solution of 9 * 9 and 16 * 16 Sudoku Boards. If you can't stand waiting fo the solution, in a few milliseconds, Isanaki 2.6b finds it for you ...
Sudoku and Wordoku
Since version 2.1, Isanaki handles both Sudoku and Wordoku boards. While the Sudoku boards contain only numbers from 1 to 9 (and letters from A to G for 16*16 boards), Wordoku boards contain only letters. Letters assignment can be done in three ways: random letters assigment, letters from random words and/or user-defined assignment. See below for details ...
Installation
Isanaki 2.6b is a simple executable file. No complex installation scripting required. Just extract the files from the .zip and copy them wherever you want. I would recommend to create a sub-directory ( i.e Isanaki) in the directory C:\Program Files.
That's it !!!
Note that Isanaki 2.6b is provided with a text file containing a list of common 9 letters Words ( in fact, a simplified version of a text file kindly provided by Michael Markov). This file is used by Isanaki 2.6b to assign letters in Wordoku Boards.
Terminology
A Sudoku Board is made up of cells (81 cells in a 9*9 Board and 256 cells in a 16*16 Board) divided in Rows (horizontal lines), Columns (vertical lines) and Boxes containing 9 (3*3) or 16 (4*4) cells. The rows, columns and boxes are called Groups. Every group must contain all the numbers from 1 to 9 ( in a 9*9 Board) or from 1 to 9 and A to G ( for 16*16 Board) At the start, some cells are filled with numbers called Clues or Givens. The numbers added when solving the game are simply called solved cells. Odd enough, it seems that no specific name describes these cells. I call them Quest.
