How to play Sudoku Levels
Sudoku Levels is a standard nine-by-nine number puzzle. You fill in the empty cells so that every row, every column and every three-by-three box contains each digit from one to nine exactly once. There are levels for beginners and for experienced solvers.
No guessing is needed in a well-made puzzle. Every step can be worked out from what is already on the grid.
Tips for Sudoku Levels
- Start with the digit that already appears most often and scan the rows, columns and boxes where it is missing.
- Use pencil marks for cells with two possibilities. They show you pairs that rule out other cells.
- Look for a row or box where only one cell can hold a certain number. That is a sure placement.
- If you are stuck, switch to a different digit instead of staring at the same area.
