In the list below you can solve a daily sudoku online or print the puzzle. I personally recommend that you do not print a Sudoku solution unless it is a very hard one. You know that a sudoko is correct by adding up the numbers on the grid and getting a total of 45 in every line in every direction. Every day a sudoku is generated for you to solve. The site keeps track of the time for you, and you can also see other players' times.
Beginners might start by looking for the "very easy" daily sudoku puzzle. The rules and the tips given on the FAQ page will get you started. Once you are comfortable with "very easy," go to the next level, an "easy" puzzle. After solving ten to twenty puzzles on each level, move to the "medium," "hard" or the "very hard" sudoko puzzles. There you will stay and tease your brain. You might want to get a coffee before starting a "very hard" sudoku, as it can take thirty minutes or more to solve. However, time flies when you are into it.
