Learn the setup. In a typical sudoku, you'll have a square grid of 9 large squares. Inside each of those larger squares will be 9 smaller squares. When faced with a puzzle, some of those smaller squares will be filled in with numbers from 1 to 9. More difficult puzzles will have fewer squares filled in.[1] X Research source The larger squares are often outlined with a darker line, while the ...Line up the rows and columns. One basic rule of the game is every column and row must have all of the numbers from 1 to 9. That means that within a row or column, a number cannot repeat.Pay attention to the numbers in the large squares. Similarly, in each of the 9 large squares, every number from 1 to 9 must appear. Once again, that means that each number can only appear once, as there's only 9 smaller squares in each larger square. So, if a large square already has the number “2” in it, you know it can’t include another number “2” anywhere in the square.Use a pencil instead of a pen. As a new sudoku player, you're going to make mistakes, and with a pen, you'll end up with a mess of a board. Instead, use a pencil so you can erase mistakes. Remember to press lightly so you can erase mistakes better.For every cell you fill in, make sure you double-check your logic; a single error could mess up the entire puzzle.
