Start with the rules
If you are new to Sudoku, begin with the basic rule: every row, column and 3x3 box must contain the digits 1 to 9 exactly once.
From there, the real skill is learning how to eliminate impossible numbers and spot where a digit must go.
Start with How to Play Sudoku, then move into beginner and easy puzzles.
