Difficulty
The selection of a Difficulty level indicates how hard it will be to solve the Sudoku puzzle. The more difficult the level, the harder it will be to figure out which numbers go into the empty blocks. Note: More difficult levels do not necessarily mean less blocks will be pre-filled in the initial puzzle.Puzzle ID
Often you may want to share a specific puzzle or print a puzzle solution some time after the original puzzle was created. This can be done by using a puzzle ID. A puzzle ID is a six (6) character identifier that represents a specific Sudoku puzzle that was previously created. You can obtain a unique puzzle ID by viewing your original puzzle; it is located in the bottom-left corner of the puzzle (e.g. MWYJKK). When you input a puzzle ID, select the Puzzle or Solution option, then click the Generate button to create the solution puzzle. Note: When a puzzle ID is used, the Difficulty level is ignored as your puzzle ID already includes this information.Generate
The Generate button allows you to create your Sudoku puzzle. Once you have selected your Difficulty level or Puzzle ID, you may select one of the following choices below and then click the Generate button.- Puzzle - This choice will create a Sudoku puzzle. You can then print the puzzle to complete it immediately, save it for a later activity, or print it to share with someone else.
- Solution - This choice will create the solution to the Sudoku puzzle. The puzzle's original empty blocks will be highlighted and filled in. You can print the solution puzzle or view it online to determine if your own solution is correct.
Reshuffle
Each time you click the Generate button you will get the same Sudoku puzzle. If you would like to create other unique puzzles, then you can click the Reshuffle button. Once you click Reshuffle, you click the Generate button once more to generate another unique puzzle. There is no limit to the number of times you can reshuffle to create additional unique puzzles.How to play Sudoku
A standard Sudoku puzzle consists of a grid of 9 blocks. Each block contains 9 boxes arranged in 3 rows and 3 columns.- When you start a game of Sudoku, some blocks will be pre-filled for you. You cannot change or move these numbers in the course of the game.
- Each column must contain all of the numbers 1 through 9 and no two numbers in the same column of a Sudoku puzzle can be the same.
- Each row must contain all of the numbers 1 through 9 and no two numbers in the same row of a Sudoku puzzle can be the same.
- Each block must contain all of the numbers 1 through 9 and no two numbers in a single block of a Sudoku puzzle can be the same.
- There is only one valid solution to each Sudoku puzzle. The only way the puzzle can be considered solved correctly is when all 81 boxes contain numbers and the other Sudoku rules have been followed.
When a puzzle is complete, the solved Sudoku puzzle appears as shown (white blocks are the ones filled in to solve the puzzle):
