Sudoku Online from SudokuDesk.com
Sudoku is a logic based numbers game. It is easy to learn, but sudoku puzzles can be very hard to solve.
The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each.
The player starts from a partially completed grid. The games are generally rated for difficulty, depending on the numbers already entered by the puzzle's creator. In each empty cell, the play must enter a digit from 1 to 9. As the puzzle progresses, every row, every column, and every 3 x 3 box should contain one of each digit. The puzzle is complete when there are no more empty cells and there are no duplicate numbers in any row, column or region.
True Sudoku puzzles will have a unique solution that can be deduced purely by logic without any guessing required. Sudoku puzzles usually are graded into categories depending on the type of logic that is required to solve them. The difficulty of the Sudoku puzzles can range from fairly simple (once a few basic rules are learned) to extremely difficult, requiring advanced application of logic.
