Scan one number
Pick a number such as 7 and check each 3x3 box for legal positions.
Sudoku tips for beginners
Sudoku tips for beginners who want fewer guesses.
Use simple habits to find safer Sudoku moves: scan with purpose, write useful notes, remove candidates, and check the board before one mistake spreads.
Sudoku tips for beginners
Make every scan answer a specific question.
A beginner often stares at the whole grid and sees nothing. Narrow the question: where can this number go, what is missing in this row, or which box has only one place left?
Scan one row
List the missing numbers in a row and test them against columns and boxes.
Scan one box
Use the box boundary first, then row and column conflicts to remove options.
Sudoku tips for beginners
Use notes as a short list, not a second puzzle.
Notes help when they stay readable. Add candidates after you have removed obvious impossibilities, and delete them as soon as a number is placed nearby.
Keep notes small
A cell with two or three candidates is useful; a cell with seven is usually too early.
Update after every placement
When you place a 4, remove 4 from notes in the same row, column, and box.
Look for pairs
If two cells in a region share the same two candidates, other cells cannot use those numbers.
Sudoku tips for beginners
Stop before the first guess becomes five guesses.
One unsupported number can create a chain of false progress. If you are about to guess, switch to another region, use notes, or run Check after a small completed area.
Change regions
A stuck row may become clear after you solve a nearby box.
Explain the move
If you cannot say why the number fits, do not fill it yet.
Use Hint deliberately
A hint is most useful when you study why that cell was available.
Keep playing
Start a puzzle now, then switch difficulty anytime.
Use these tips on a live board. Start easy, explain each move, and let the puzzle open slowly.

Beginner Sudoku tips FAQ
What is the best first Sudoku tip?
Do not scan the whole board at once. Ask one narrow question and follow it until it stops helping.
Are notes cheating?
No. Notes are a normal solving aid, especially while learning elimination.
How do I stop guessing?
Leave uncertain cells blank, solve a different region, and return when more numbers create new constraints.
Should beginners play fast?
No. Accuracy and understanding matter more than speed. Faster solving comes after the patterns feel familiar.
