The ability to solve Sudoku puzzles is of great importance among Sudoku fans. [br]There are two main strategy approaches. One is to determine the candidate directly and the other is to exclude certain candidates. [br]Simple Sudokus can usually be solved intuitively and by concentrated searching. The two sufficient beginner techniques are explained under "Naked Single", "Hidden Single" and under "Naked/Hidden Pair". [br]http://hodoku.sourceforge.net/en/tech_naked.php
Identify and remove [ ≠ ]candidates by rules of[br][list][*][url=http://walter.bislins.ch/projekte/index.asp?page=Sudoku%3A+Locked+Candidates]Locked Candidates[/url][/*][/list]Es gibt diese Methode in den zwei Varianten [b]Box/Line[/b] und [b]Line/Box[/b]. In beiden Varianten können bis zu 6 Kandidaten gelöscht werden.
