Learn Sudoku: solving techniques and strategies
Study Sudoku in a deliberate order: learn the rules, scan for singles, preserve accurate candidates, and move to eliminations only when the simpler deductions stop producing progress.

A practical solving routine
Start with the fullest units, check every candidate against its row, column, and box, and rescan after each certain move. Notes are a record of possibilities, not guesses. When a pattern removes a candidate, update the whole affected unit before escalating to a harder technique.
Practice what you learn
Use the lessons with a free English Sudoku board. Choose Easy for visible clues, Medium for candidate comparison, or Hard when you want longer deductions.
