The 18th century Swiss mathematician Leonhard Euler apparently developed the concept of "Latin Squares" where numbers in a grid appear only once,across and up and down.In the late 1970's,Dell Magazines in the US began publishing what we now call Sudoku puzzles using Euler's concept with a 9 by 9 square grid.They called it Number Place,and it was developed by an independent puzzle maker,Howard Garnes.
Each Sudoku has a unique solution that can be reached logically without guessing.Enter digits from 1 to 9 into the blank spaces.Every row must contain one of each digit.So must every column,as must every 3x3 square
