Sudoku is a logic and brain teaser numbers puzzle game which is played on a 9x9 square grid and is divided into a nine 3X3 grid producing nine rows and nine columns, for a total of 81 small squares. Your aim is to fill out all empty squares so that each line consists of the same numbers. You must solve these very hard logic & brain teaser puzzles; the remaining squares must be filled in with the numbers 1 through 9. Your numbers must appear only once in each row, once in each column and once in each 3x3 square. Each section has 50 game puzzles, lettered A through F. After every lettered section, the same lettered solutions to each puzzle will follow.
