Sudoku : Classic
Puzzle
Free · Designed for iPad. Not verified for macOS.
Every puzzle has exactly one solution, so you can always reason your way there. Four difficulty levels, pencil notes, and your board saved right where you left it.
Sudoku Classic is a clean, distraction-free take on the classic number puzzle. Every board is generated fresh with exactly one solution, so you can always reason your way to the answer. No guessing required.
FOUR DIFFICULTY LEVELS
Easy, Medium, Hard and Expert. Each level starts you with fewer given numbers, so the challenge grows as you do.
BUILT FOR COMFORTABLE PLAY
• Pencil notes for tracking candidates in any square
• Undo any move, or erase a square completely
• Row, column and box highlighting to guide your eye
• Matching numbers highlight together across the board
• Notes clear themselves automatically as you place numbers
PLAY YOUR WAY
Turn off the three-mistake limit if you would rather play without pressure — mistakes are then only counted, and the game never ends. Hide the timer for a relaxed session. Switch off the highlighting for a purer challenge. Every assist is a toggle in Settings.
HINTS WHEN YOU NEED THEM
Stuck on a board? Reveal a single square and keep your momentum.
PICK UP WHERE YOU LEFT OFF
Your game saves itself. Close the app mid-puzzle and the board, your notes and the timer are all waiting when you come back.
TRACK YOUR PROGRESS
Best completion time for every difficulty, plus statistics covering games started, games completed, win rate and average time.
LIGHT OR DARK
Switch between light and dark whenever you like, independent of your system setting.
