How to play Sudoku.
The puzzle is most frequently a 9x9
grid made up of 3x3 subgrids (called "regions").
Some cells already contain numbers, known as
"givens". The goal is to fill in the empty cells,
one number in each, so that each column, row, and
region contains the numbers 1-9 exactly once. Each
number in the solution therefore occurs only once in
each of three "directions", hence the "single
numbers" implied by the puzzle's name.
