Tips

Look for naked and hidden singles and pairs in rows, columns, and boxes. Even in hard puzzles, these fundamental techniques can eliminate many possibilities.
Employ advanced strategies like X-Wings, Swordfish, and Jellyfish. These complex patterns help identify candidates in shared rows or columns.
Use pencil marks (or candidates) effectively. Don't just fill them in; actively use them to spot advanced techniques and deduce further moves.
Scan the grid systematically. Instead of jumping around, focus on one number at a time, checking its placement across rows, columns, and boxes.
Don't be afraid to backtrack if you hit a dead end or suspect an error. Sometimes a different approach or a corrected candidate is all you need.
