How to play sudoku games

Don’t let the rows of numbers put you off! Sudoku is not a math game; it is actually just about logic and spotting patterns. The rules are surprisingly simple and easy to pick up, so anyone can learn to play in no time.

The Rules of Sudoku

The game takes place on a large grid made up of 9x9 squares. This big grid is split into nine smaller 3x3 blocks. Your objective is to fill the entire 9x9 space using the numbers 1 to 9. You have to arrange them so that every single row, every single column, and every 3x3 block contains all the numbers from 1 to 9 exactly once. The horizontal rows, vertical columns, and each bold printed block of 3x3 cannot contain any duplicate numbers.

By following these rules, you can solve the entire board using a step-by-step process of elimination. By analysing the numbers already visible, you can rule out the digits that can no longer fit into that specific row, column, or block. Keep going until you find the only possible number left for each empty square.

Taking Notes

You can use the built-in note feature (usually a button with a pencil icon) to jot down your 'candidate numbers'. These are the digits you think might belong in a certain square. As you progress, you can double-check your clues and delete them one by one until you are certain of the answer.

Once you find the correct number for a box, just toggle the note feature off to type your final answer. When you fill a square, remember to look at the surrounding boxes and update your notes. Leaving old, incorrect pencil marks active is one of the biggest reasons players get stuck and have to start over.

Sudoku Pitfalls to Avoid

Here are a few common blunders that players often make. Once you know what to watch out for, you can dodge them easily:

• Guessing randomly: Every puzzle is designed to be solved purely through logic. If you start guessing when you get stuck, your mistake might seem fine at first, but it will eventually cause a chain reaction of errors later on.
• Tunnel vision: Don’t spend ages staring at just one tricky square. You might be missing a much easier move somewhere else on the board. Rows, columns, or 3x3 blocks that are nearly full are good places to look for clues.
• Overlooking hidden pairs: If a square is giving you a headache, you might be forgetting a clever trick: looking for pairs of boxes that can only accept two specific numbers. Finding these pairs can help you clear out those candidate numbers from the rest of that particular row or column.
• Cluttering your screen: Pencilling in too many candidate numbers and forgetting to clean them up makes the screen incredibly confusing. Keep your digital pencil marks tidy!

Fresh Challenges Every Single Day

Practising regularly is the best way to master any new skill. You can train your eyes to spot patterns much quicker simply by playing on a regular basis. Keep your mind active by making these puzzles part of your everyday routine. Every morning brings a brand-new grid to solve, making it a perfect partner for your morning tea or a quick afternoon break from work.
