Sudoku is an ancient number placement game, where digits 1-9 are placed on a 9x9 grid. This grid is separated into 3x3 blocks.
To win, digits 1-9 must be placed so that each row, each column, and each block contains all the digits 1-9 with each digit appearing only once.
The puzzle was popularized in 1986 by the Japanese puzzle company Nikoli under the name Sudoku meaning single number.
