Sudoku: Offline Number Puzzle

Play classic Sudoku the calm way: no pop-up ads and nothing that interrupts your game. Solve sudoku offline anywhere — no wifi needed — with four more number puzzle games built into the same app.

How to Play Sudoku
Soduku rules are simple. Fill the 9x9 grid so every row, column, and 3x3 box contains the numbers 1 to 9 exactly once. Every puzzle has a single solution, so you never have to guess — just pure logic. Choose from seven difficulty levels, from Beginner to Diabolical. Take pencil-mark notes, use a smart hint that shows you the solving technique when you're stuck, and undo a wrong move. A new Daily Challenge sudoko is waiting every morning.

Five Games in One App
🔢 Sudoku – the classic 9x9 logic puzzle with thousands of boards
🧩 Number Match – clear the board by matching pairs that are equal or add up to 10
🔀 Merge – slide and combine matching tiles to build bigger numbers, 2048 style
🎯 Sort – the classic sliding puzzle: slide the tiles on a 3x3 or 4x4 board until they're back in order
➕ Cross Math – a number crossword: fill in the missing numbers so every equation across and down is correct, from addition and subtraction to multiplication, division, and trickier operators on harder levels

Play Anywhere
Everything works completely offline. Play on a flight, on the train, or in a waiting room — no wifi, no mobile data, no problem. There are no ad breaks to wait through and no connection to drop: your suduko loads instantly, and progress saves automatically so you can pick up right where you left off.

Good for Your Brain
Ten focused minutes of sodoku a day is a simple brain workout: solving trains concentration, memory, and logical thinking, while the math puzzles keep your mental arithmetic sharp. Relaxing when you want to unwind, challenging when you want a tougher soduko.
