Sudoku is a logic-based number puzzles game. In Sudoku, you will be given a partially completed grid. It is made up of a series of rows and columns. The goal is to arrange the numbers 1–9 in each row, column and region of the grid. Each row, each column and each region contains all the digits from 1 to 9.

Sudoku provides an easy-to-use interface. All that you have to do is to fill in the grid.

There are no wrong answers, no penalties, no time limits. You will be given a hint whenever you try to fill in an area without any numbers.

Fill in the grid until you are given a solution. After you have solved the puzzle, you can get a new puzzle by tapping on the 'Solve' button.
