Sudoku is a logical puzzle consisting of a 9x9 grid, divided into 9 blocks, each with 3x3 cells. The goal is to fill in the empty cells, one number in each, so that each row, column and block contains the numbers 1-9 exactly once. Each number in the solution therefore occurs only once in each of three "directions" (wikipedia).
