Tips & Tricks
Beginner Tips
- Start with singles. Fill cells that have only one candidate.
- Use notes early. Candidates prevent guesswork and highlight contradictions.
- Scan systematically. Sweep rows, columns, then boxes, in a loop.
- Hide the timer if it distracts you. Focus on accuracy first.
Advanced Strategies
- Naked and hidden pairs: two cells share the same two candidates, or two candidates exist only in two cells.
- Locked candidates: if a number’s candidates in a box lie on one line, eliminate that number from the rest of that line.
