Sudoku offers multiple difficulty levels to suit all types of players, from complete beginners to experienced solvers. Lower difficulties start with more numbers already filled in, while harder levels give you fewer clues and require more advanced logic and strategies.
A great starting strategy is to scan each row, column, and 3x3 box to find cells where only one number can logically fit. As you advance, techniques like 'naked pairs' and 'elimination' help you tackle harder puzzles — use the notes feature to jot down possible numbers in tricky cells to keep track of your options.
Right-click on an empty cell or activate the notes mode to pencil in multiple candidate numbers without committing to a final answer. This is especially useful on harder difficulty levels where a cell could potentially hold several different numbers until you gather more clues from surrounding rows, columns, and boxes.
