Sudoku is a number puzzle that requires logical thinking. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 regions contains numbers from 1 to 9 only one time each. The puzzle starts with a partially completed grid.
The Sudoku puzzle was invented by an American architect, Howard Garns, in 1979. But it first became popular in Japan in the mid 80s. Sudoku is the Japanese word for "single digit."
