How to play Sudoku 30 Levels?
Identify the 3×3 boxes, which are usually labelled with a letter or number to help you keep track of them more easily. Then, fill in any known numbers that are given. After that, look for “clues” of single numbers hidden among the other tiles and use cross-referencing techniques like pencil marks to solve for more numbers as you progress. Challenge yourself by taking your time and being patient until you can no longer find any clues—this means you’ve solved the puzzle!
