Sudokers

Choose a difficulty or a mode such as Classic, Time Attack, or Daily Challenge. Fill the grid with numbers 1 to 9 so each row, column, and 3x3 block contains every digit without repeats. Use Notes to pencil in candidate numbers and remove them as you narrow possibilities. Enable smart highlights to spot conflicts, singles, and useful patterns that guide your next move. Tap Hint for a logic based step that teaches a technique without spoiling the entire solution. Complete puzzles to earn stars, unlock harder sets, and climb the leaderboard.
