Sudoku Everyday: Easy, medium & hard puzzles

Sudoku Everyday - A clean and classy, no-frills Sudoku experience. Comes with thousands of puzzles classified into 5 difficulty levels (very easy, easy, medium, hard and extreme) to give ample play-time for everyone from newbies to experts.
How to play sudoku - Select a number from the number-pad below the grid. Apply the selected number on empty grid cells where you believe that number is the right fit. Once done, select another number from the number-pad and repeat the process. Once you have filled in all the empty cells in the grid with their correct solutions, you win.
Difficulty levels - Puzzles are classified into 5 difficulty levels depending on the percentage of cells that are pre-filled in the sudoku grid when starting the game. Very easy puzzles will start with a large percent of pre-filled cells, whereas Extreme puzzles will have the least pre-fill percentage.
Can I create my own sudoku puzzle?
Yes, Sudoku Everyday comes with a feature called "Create Puzzle" which allows you to do exactly this. You will be presented with an empty grid where you can fill the grid cells of your interest with the numbers you want. You can use this feature to either create your own puzzles or to have a digitally playable version of your favourite puzzles from newspapers or books. As you're filling up the grid, click the validate button to check whether the entries make a playable puzzle. Once validated, you can start solving your own sudoku puzzle. Isn't that amazing? Have fun solving your own sudoku with Sudoku Everyday.
Clearing filled cells: You can clear cells already filled using the "eraser" button that appears to the right of the number pad. Just like the number pad, you can "select" this once and then clear as many cells as needed by tapping on them on the grid.
Notes: For solving very hard puzzles, you can use the "note" button to pencil-in temporary notes on cells. When you place numbers on grid-cells with the note mode ON, the numbers will be added as notes. This can be especially useful in hard sudoku puzzles.
Hints: If you find the going hard, you can use the hint feature to fill-out any one cell in the grid with the correct solution.
Settings: For a more challenging experience, you can go to "Settings" and turn the "Highlight Errors" option off.
