What you need to know
-
Pick a puzzle with a solution
Use Nikoli's Sudoku sample below or an easy puzzle from a library book so you can check your work afterward.
-
Keep marks erasable
A pencil, eraser, and paper are enough; leave room for small notes inside each cell.
-
Keep the rules beside you
Begin with standard Sudoku, without diagonal, cage, or other extra rules that change which moves are allowed.
Pencil-and-paper puzzles suit short, quiet sessions where you enjoy working out why an answer fits. Start with one easy Sudoku. If you prefer drawing boundaries or paths, browse Nikoli’s other logic puzzles after this first attempt.
Make a move you can explain
Copy the sample carefully, keeping printed clues distinct from your own answers. Check the copy against the original before solving and cover the solution.
Under Nikoli’s standard Sudoku rules, each row, column, and bold-outlined 3-by-3 box must contain the digits 1 through 9 once each. The digits are labels; you do not add them together.
Look for a row with few empty cells. List its missing digits, then check each empty cell’s column and box. Cross out any digit already present in either. When just one possibility remains, write it in.
For example, if a row lacks 2 and 7, and one empty cell’s column already contains 7, that cell must be 2. Check its box too. A conflicting 2 means an earlier entry or copied clue needs checking.
Work through a pause
Small pencil marks are possibilities, not answers. Update them when you place a digit in a connected row, column, or box. You can also choose one missing digit and look for the only cell it could occupy within a box.
If nothing follows, scan another area. Avoid filling a cell just because a number looks plausible. After several unproductive minutes, request one explained hint or inspect the sample’s partly solved stage, then continue yourself.
A repeated digit is a reason to stop and trace recent entries. Erase the unsupported move and reconsider anything that depended on it.
Check the result and choose another
Before uncovering the solution, check every row, column, and box for repeats and gaps. Record one deduction you understood and one place you needed help.
Try another easy grid using the same method. When those moves feel familiar, choose a different puzzle from the library and read its rules from scratch. Keep difficulty low while learning a new format.
