21 Sudoku Singles Chain

Welcome to this Sudoku Video Turorial Sudoku Singles Chains. It is part of a series of Sudoku Tutorials that I am basing closely on the Sudoku Analyses Techniques which can be found on the LittleGogs website Analyses Section http://www.littlegogs.com/analyses/nlanalyses.shtml Singles Chain: A linked Chain of single Possibles. The ends of the Chain (coloured black) and all the linking elements (coloured pale green) have the same value. If one end of the Chain is 'false', then the other must be 'true' and vice-versa. Any Possible that can 'see' both ends of the Chain may be removed. http://www.littlegogs.com/analyses/singles-chains.shtml Cracking The Cryptic Website – I’m using as a source of Soduku Examples Im also using SudokuOfTheDay as a source of some examples in some tutorials https://www.sudokuoftheday.com/dailypuzzles/
