sudoku,
a data directory which
contains examples of Sudoku puzzles. A 9x9 grid of 3x3 boxes
and 81 cells is presented. In a completed Sudoku, the digits 1
through 9 are placed in the 81 cells, in such a way that each row,
column and box contains each digit exactly once. A Sudoku puzzle
is a partially completed Sudoku in which the user must figure out
how to complete the pattern.
