About this game

Sudoku starts easy. How far can you go?

Go from relaxing Easy puzzles all the way to Absurd challenges built for experienced solvers. With 8 truly different difficulty levels, smart hints that teach you the logic, advanced solving techniques, daily challenges and more, this is Sudoku designed to grow with you.

🧩 8 DIFFICULTY LEVELS — EASY TO ABSURD

Easy, Medium, Hard, Expert, Master, Diabolical, Infernal and Absurd.

Start with classic Sudoku puzzles at your own pace, then work your way up to challenges that demand increasingly advanced logic. Higher difficulties are built around real solving techniques — not simply puzzles with more empty cells.

Think Expert is hard? Keep going.

💡 SMART HINTS THAT ACTUALLY TEACH

Stuck? A hint doesn't simply reveal the answer.

The smart hint system analyzes the current board, identifies a solving technique you can use next, and highlights the relevant cells and candidates so you can understand the logic yourself.

Learn to recognize patterns instead of depending on answers — and spot them on your own the next time.

🧠 MASTER ADVANCED SUDOKU TECHNIQUES

As the difficulty increases, so does the logic.

Learn and practice techniques including hidden pairs, locked candidates, X-Wing, XY-Wing, Swordfish and more.

Whether you're learning advanced Sudoku or already know your wings and fish, the highest levels are designed to give experienced players a real challenge.
