So to solve those puzzles, we need to use the counter logic. Accordingly, we introduce here the Principle of the Least Choice (PLC) to settle the multiple choice situations. With this novel strategy, we demonstrate how easy it is to crack down five well-known hardest puzzles ever designed. ..........KEYWORDS: Sudoku, Puzzle, Row move, Column move, Block move, Box move, Grid move, Terminating move, Law of unique solution, Candidate, Principle of the Least Choice. Therefore we solemnly declare that SUDOKU9.0 turns “Sudoku of level 9” into a “Piece of cake”!
