Online Sudoku Puzzles

Sudoku puzzles also known as Su Doku or Number Place are easy to learn, but not necessarily easy to solve. Every row, every column and every 3x3 box must contain the numbers 1 through 9. You do not need to guess. Our daily puzzles are always solvable with pure logic although the difficulty varies greatly from mild to fiendish. Sudoku will appeal to strategy game, brain teaser, crossword, solitaire or patience addicts, and is good exercise for your brain. Computers can solve most games easily while most humans find them very challenging. Older sudoko puzzles are available by selecting a date from the daily drop down list.
