1. Familiarize yourself with the rules.

Before you even attempt to play a game of Sudoku, make sure that you familiarize yourself with the rules. While it might seem pretty straightforward, reading the rules can really help to get your mind around the actual objective of the game. You might even figure out a few techniques of your own that make the game easier, based on the rules.

2. Start small.

Beginners cannot start playing Sudoku on just any level. All Sudoku World Champions had to start somewhere, and that is usually with the easiest puzzle. You will find that the game includes various levels of difficulty. Beginner players should start with the most basic puzzles, and stick with them until they are comfortable with the process and techniques of puzzle solving. You can download a few beginners Sudoku puzzles online, or get a Sudoku exercise book to practice with – they usually have a beginner’s publication or section.

3. Keep progressing.

It’s important not to stagnate when you start playing Sudoku. As you begin finding the easy puzzles quick and straightforward to solve, start looking for puzzles a little more complicated. As each difficulty level becomes easier for you, keep progressing. This is a great way to train the brain and ensure that it remains sharp and active.

4. Work on the easiest sections first.

Beginners stand to benefit from starting with the easiest play. Within the main Sudoku grid, there are sub-grids with some numbers already provided as clues. Some grids will have more numbers than others. If there’s a grid that looks easier to start with, go for it. It is all a process of trial and error anyway, so if you do something wrong, you can always start over. You can start by adding numbers where it seems the most obvious fit.

5. Work with a pencil & eraser.

It’s impossible to complete a Sudoku puzzle as a beginner without having to make a few changes or try to figure out the answer through the process of elimination. To do this with a pen will simply give you a headache as you run out of space or make a mess of the grid. With a pencil and eraser, there’s nothing “set in stone,” and you can make changes and change your mind as often as you like, consequence-free.

6. Apply what you know to figure out what you don’t.

Apply what you know to figure out what you don’t is called “process of elimination.” If a grid has numbers 1, 2, 4, 5, 6, 8 – this is what you know. Now you can easily tell that the numbers 3, 7, and 9 are missing. These are the numbers required to complete that grid. This might not help you to know which blocks each of these missing numbers belongs in, but it can help you to quickly narrow things down.

8. Use the cross-hatching technique.

As a beginner Sudoku player, cross-hatching can be a very useful tool and technique for solving the puzzle. Cross-hatching is a process of cross-referencing rows and columns to find out which of the remaining numbers is most unique to that particular grid. Doing this also helps you to remain aware of all the numbers that you are placing in the empty blocks.

9. Avoid guessing.

Sudoku is a game of logical thinking and organizing. There should little to no guesswork involved. If you guess where a number should be placed, it could affect the rest of your puzzle and even make it impossible to solve. The only time you should place a number in a block is when you have taken the time to weigh up the evidence that you have and can make an educated, logical decision.

10. Take your time to figure it out.

When you are new to Sudoku, there is no need to rush through the problem-solving process. The more you rush, the more flustered you will be, and that is when mistakes easily happen.

11. Use a “one pass” approach.

One pass is a process where a player scans the grid and finds where a number cannot be filled in. Once you know where a number cannot be placed, it’s far easier to narrow down where it can be. Often this method results in puzzles being solved very quickly.

12. Brush up on knowledge of Sudoku tricks.
