What is sudoku?
Sudoku is a 9 by 9 number logic puzzle. The grid splits into nine 3 by 3 blocks. Some cells have a digit filled in already. Your job is to fill the rest so that each row, each column, and each block holds the digits 1 through 9 with no repeats.
Howard Garns, an Indianapolis architect, designed the modern form in 1979 as "Number Place." A Japanese publisher rebranded it as Sudoku in 1986, and it went global in 2004 when The Times of London began printing one daily.
Sudoku is about logic, not math. You can solve every puzzle by checking what fits in each cell. Easy puzzles only need single candidate and hidden single. Expert puzzles need naked pairs, x-wing, and other techniques.
