Organic Sudoku

About Organic Sudoku Android Game

Organic Sudoku is the purest form of Sudoku on a mobile device. There are no distracting ads or timers, just lots of Sudoku you can solve at your own pace. Organic Sudoku is as close as you will get to a stress-free "paper and pencil" Sudoku experience on a mobile device. Organic Sudoku seeks to provide a balance between slow-paced, relaxing entertainment and challenging brain exercise to keep you in top mental shape without adding to your daily stress.

Game Features:
* Absolutely free, no ads or in app purchases!
* Works offline
* Four Sudoku difficulty levels: from Easy to Extreme
* Easy note taking
* Saves progress automatically
* Optimized for smartphones and tablets
* Over 200 free Sudoku puzzles!

Sudoku puzzles are organized into "books" with four puzzles of varying difficulty on each page, from easy to extreme. After solving at least one puzzle on a page, the next page is unlocked.

Organic Sudoku is very easy to play. Use an in-game keypad to enter numbers. Game highlights numbers that match the selected number to help you see if your move is valid. The game will not warn you about invalid moves or provide hints though. This is to ensure that the game is challenging enough to provide the benefits.

If you cannot solve a puzzle, you can give up and see the solution. You can start over after this and have another go. The game also allows you to take notes if there are multiple possible numbers for a given cell. You can also undo moves if you make a mistake or want to try something and go back to a previous position if it does not work out.

Organic Sudoku works offline and takes very little space on your device.

The game was tested with Google talk-back and physical keyboard to make it more accessible. I am keen to further improve accessibility for users with vision, motor or other impairment. Please email me your suggestions.
