Sudoku - Classic Logic Puzzle

Train your brain. Every day.

Sudoku in a modern, clean design – no sign-up, with a daily challenge and online leaderboards. Every puzzle has exactly one solution, and difficulty is rated the way a human solves it – so Easy is really easy and Expert is truly rewarding.

★ FOUR DIFFICULTY LEVELS
Easy, Medium, Hard and Expert – from 45 down to just 24 given digits. New puzzles are generated in a split second, so you will never run out.

★ DAILY CHALLENGE
One new puzzle every day – the same for all players. Finish it to extend your streak of days in a row and earn bonus points. The calendar shows the days you completed, and you can catch up on the challenges you missed.

★ ONLINE LEADERBOARDS
Compare your score with other players: daily, weekly and all-time rankings for every level, plus a separate daily challenge leaderboard. Pick your own nickname or connect with Google Play Games. Playing offline? Your scores will wait and upload automatically.

★ POINTS FOR EVERY GOOD MOVE
Earn points as you play – for correct digits and completed rows, columns and boxes. A streak of error-free moves multiplies your points, and a fast game without mistakes gives extra bonuses and three stars.

★ HANDY TOOLS
• Notes – pencil in candidates; they clear automatically when you place a digit
• Undo – full move history
• Hints – show the right digit when you get stuck; get more by watching a short ad
• Highlighting of the row, column, box and matching digits
• A counter on every digit – see how many are left to place
• Three hearts – every mistake is shown right away, and after a loss you can keep playing with extra hearts

★ LEARN IN A MINUTE
New to sudoku? An interactive step-by-step tutorial teaches the rules, notes and hints on a real board. The guide with scoring rules is always at hand.

★ REMINDERS THAT DON'T NAG
At most one notification a day at the time you choose – so you never break your streak. Nothing arrives if you have already played today.

★ PICK UP WHERE YOU LEFT OFF
The game saves after every move – leave at any time and continue later.

★ POLISHED DOWN TO THE DETAILS
Smooth animations, fireworks when you win, pleasant sounds and haptics (can be turned off). Large cells and digits that scale with your system font size. Works on phones, tablets and foldables – in portrait and landscape. Available in English, Polish and Russian.
