Sudoku mega

If our other sudoku puzzle was too easy for you, try this one. It's harder than the other one.
Sudoku is the number puzzle. Although it is a number game, Sudoku requires no mathematical skills - just a keen grasp of logic and plenty of patience.
The rules are simple: You simply fill in all the squares in the grid so that each row, column and each of the 3x3 squares contains all the digits from 1 to 9 without repeats or omissions. It sounds a piece of cake, but the really tricky Sudoku puzzles can leave you pulling your hair out.
This game gets updated everyday. So, you can expect a new one tomorrow.

Instructions:
You can choose sudoku of each day by choosing it from the dropdown menu in the game box below.
You can also save the game to play it later by clicking on the save button at the top on the game box.
