Each puzzle has one and only one unique solution, and each can be solved using only pure logical deduction-guessing and trial-and-error methods are never required for these puzzles. If you're new to numbergrids, try the smaller puzzles first, then move on to the larger ones.
Sudoku is a number puzzle consisting of a 9 x 9 grid in which some cells contain clues in the form of digits from 1 to 9. The solverâs jobs is to ï¬ll in the remaining cells so that each row, column and 3Ã3 box in the grid contains all nine digits. Thereâs another unwritten rule: the puzzle must have only one solution. So grids cannot contain just a few starting clues. Itâs easy to see why.
