Sudoku

Train your brain. Every day.

Sudoku for Android 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.

Four difficulty levels

Easy, Medium, Hard and Expert – from 45 down to just 24 given digits. New puzzles are generated in a split second.

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. You can catch up on the challenges you missed.

Online leaderboards

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

Points 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, undo and hints,
• highlighting of the row, column, box and matching digits,
• a counter on every digit – see how many are left to place,
• an interactive tutorial for beginners,
• daily challenge reminders (optional),
• the game saves after every move.

The app is available in English, Polish and Russian.
