Speed Sudoku: How to Become Faster

For many players, it is a special thrill not only to solve Sudokus but also to do so in the shortest possible time. To become faster, it is not enough just to know the basic rules. You must proceed systematically and recognize certain patterns quickly.

Systematic Scanning

The key to speed is a systematic approach. Scan the grid specifically for the numbers 1 to 9. Look for blocks where a certain number is still missing, and check whether the corresponding rows and columns are already blocked.

Focus on Almost Full Areas

Concentrate on rows, columns, or blocks where only a few numbers are missing. Here, the probability is highest to quickly find the missing numbers through a simple process of elimination. This brings quick successes and fills the grid.

Use Notes Sparingly

Entering and updating notes takes time. Try to get by without notes for as long as possible in easy and medium Sudokus. Keep possible candidates in your head. Only use notes when you really cannot progress any further.

Learn to Recognize Patterns

With increasing experience, you will recognize certain patterns and constellations more quickly. You will see at a glance where a number must go without having to think long. This intuitive recognition is the most important factor for fast solving times.

Practice Makes Perfect

As with everything, practice makes perfect in Sudoku. The more puzzles you solve, the faster you will become. Set realistic goals and try to regularly beat your own best time. Do not get discouraged if it takes longer sometimes.

Frequently asked questions

How important is pen handling when solving on paper?

Very important. A soft pencil and a good eraser save time. Write the numbers clearly to avoid confusion.

Should I always start scanning with the number 1?

That is a good method for the beginning. Later, you can also start with the number that is already most frequently given in the grid.

Are there special techniques for fast solving?

Yes, techniques like ‘cross-hatching’ help to identify missing numbers in a block very quickly.

Is it normal that I need much longer for hard Sudokus?

Absolutely. Hard Sudokus require complex logical deductions, which simply take more time than pure scanning in easy puzzles.
