Sudoku is a logic-based number-placement puzzle that doesn't require any special math skills or calculations to find the solution.

Some players prefer solving the puzzle using a pencil to write possible candidates in a blank before arriving at the unique solution for that cell. For example, if you find three digits that can be positioned in a particular blank, write those three digits with a pencil in that cell, and erase them when you get the correct answer.

To solve your puzzles smartly, you should use a Pencil technique. This way, you can enter temporary numbers in a square instead of entering an incorrect number and losing lives. If you feel a blank square has possibilities of more than one number, you can fill in the temporary numbers for reference. These temporary numbers will not reduce your score or lives.

When you are certain of the correct number for a particular blank cell, you can also erase these numbers by selecting the Erase button beside the Pencil. You can turn the Pencil mode on or off by tapping on the pencil.
