SAMURAI SUDOKU 174
Saturday, October 08, 2011
Each Samurai Sudoku puzzle consists of 5 overlapping “classic” 9x9 Sudoku sub-puzzles. Each 9x9 sub-puzzle must be solved according to the rules of Sudoku: each row, column and 3x3 box must contain all digits from 1 to 9 - therefore, digits cannot be repeated. Each Samurai Sudoku puzzle has one solution only.
