Valid puzzles guarantee a single logical solution. Candidate notes help track options safely.

Techniques

Four essentials to solve consistently from easy to expert.

Singles

Place a digit when a cell or unit allows only one candidate. Sweep rows, columns, and boxes in a steady rhythm.

Pairs

Two cells in a unit share the same two candidates. Block those digits elsewhere in that unit to thin the grid.

Box/Line

If a digit’s candidates in a box lie on one line, eliminate that digit from the rest of that row or column.

X-Wing

Two rows or columns restrict a digit to two spots each. Align them to clear the same digit elsewhere.

Arcade Loop

Scan for singles → refresh candidates → lock pairs → box/line trims → escalate to patterns only when stalled. Repeat with calm tempo.

FAQ

What defines a valid Sudoku puzzle

A unique logical solution follows from the givens without contradictions or guessing.

Do I need to use notes

Notes prevent oversight and enable safe elimination chains as puzzles get harder.

How do difficulty levels differ

Easy boards flow with singles and pairs; hard boards require box/line and pattern tools like X-Wing.

Is guessing acceptable

We favor deduction. If you branch, label it and revert at the first conflict.
