Sudoku - Classic Sudoku Puzzle v6.9

Get ready to put your logic skills to the test with the popular Sudoku classic Zen puzzle game, now available on Android! Also known as Number Place, this engaging game is loved by millions and is the most popular combinational number-placement puzzle in the world.

To play, simply fill the 9×9 grid with digits so that each column, row, and each of the nine 3×3 sub-grids contains all of the digits from 1 to 9. With four perfectly balanced difficulty levels to choose from, you can challenge yourself at any skill level.

Complete daily challenges and collect trophies to show off your achievements. Turn on/off Notes (Pencil) mode as you like, highlight duplicates to avoid identical numbers in a row, column, and subgrid, and receive intelligent hints whenever you get stuck.

Choose from two input modes: Cell first or Digit first, and enjoy super smooth interfaces like on paper/newspaper. The unlimited undo and eraser features will help you get rid of mistakes, and highlighting of a row, column, and subgrid related to the selected cell will help you discover patterns quickly.

The app also automatically saves your game when you get a phone call, switch applications, or lock the phone so you don't lose progress.
