Endless Sudoku puzzles, without interruptions.

Enjoy Sudoku at your own pace, with five difficulty levels, daily challenges, interactive lessons and guided hints that actually teach you how to solve.

Every puzzle is freshly generated on your device and has exactly one solution. Play as much as you like, without interruptions between games.

LEARN WITH GUIDED HINTS

Stuck on a square? Don't just reveal the answer, learn how to find it.

Guided hints walk you through the logic step by step, showing you how to solve a square and explaining why each step works. Learn to recognise techniques and become a better solver with every puzzle.

• Step-by-step guidance through the solving process
• Clear explanations of the logic behind each move
• Turn hints off for a traditional pen-and-paper experience

MASTER SUDOKU WITH INTERACTIVE LESSONS

Learn Sudoku techniques, from the basics of Naked Singles to advanced strategies like X-Wings and Swordfish.

Each lesson guides you through a technique on a real Sudoku board, explaining how it works and when to use it. Then put your new skills into practice with three puzzles designed around that technique.

FIVE LEVELS, RATED BY LOGIC

Unlike games that judge difficulty by the number of starting clues, our puzzles are rated by the techniques needed to solve them. That means a consistent challenge at every level.

• Easy: perfect for beginners
• Medium: a little more thinking required
• Hard: put your solving skills to the test
• Expert: for experienced Sudoku players
• Master: the ultimate logic challenge
