How To Play Sudoku
Sudoku is a puzzle game that first appeared in the 1970’s, but remained in relative obscurity until the early 2000’s. Since then it’s become a mainstay in newspapers across the world, and spawned dozens of offshoots and variations.
In Sudoku, the player is presented with a board consisting of 81 cells arranged in a 9x9 formation. The board is further broken down into 9 3x3 boxes. The goal of Sudoku is to use the numbers 1-9 in such a way that each row, column, and box has one of each of these digits, and only 1.
Each board comes with several numbers already scattered across the board, which cannot be changed, and set the tone for the entire puzzle.
