Sudoku International can be seen as a generic or a varied form of the original Sudoku game. It expects a wider audience, or a wider mind!

Sudoku International can be played on SMARTPHONES and TABLETS of various sizes.

Proper Sudoku (with a unique solution) is also part of this game. An increased difficulty feature, which is currently experimental, is included in this game.

You CAN SAVE your game mid-way, and then continue and finish it off some time later. Hints (solutions) are also provided.

You can also mark possible numbers for future reference, just as you would scribble a rough number in pencil on a paper-based Sudoku.

And furthermore, when you complete a game, you can SAVE its SCREENSHOT, for your own collection or to share and show it off to others.

Sudoku International LITERALLY has UNLIMITED PUZZLES TO SOLVE,
thanks to its automatically generating mechanism.

Sudoku International also has DIFFERENT GENRES to choose from.
In this game, you can enjoy Sudoku at DIFFERENT LEVELS, from a 2x2 grid to a 9x9 grid. Whatever your age may be, whether you are a beginner, an intermediate, or an advanced player, there is always something for you to play.

You can also enjoy Sudoku in DIFFERENT LANGUAGES:
English Numerals
Roman Uppercase Numerals
Roman Lowercase Numerals
Hebrew Numerals
Arabic Numerals
Indian Numerals
Chinese Numerals
Tally Marks - English Variant
Tally Marks - Latin Variant

Note:
Arabic, Urdu, and Persian numerals are similar.
Indian numerals imply the Devanagari format, which is relatable in the sub-continent.
Chinese, Japanese, and Korean numerals are exactly the same.

While the different languages are meant to encourage and propagate the game across the globe, it could also encourage a player to stretch their bounds (their comfort zone), and expand their minds. Anyone can, and should play this game across the spectra of different levels and different languages.

Everyone knows this pattern from their mobile phone keypad:
1 - 2 - 3
4 - 5 - 6
7 - 8 - 9
Most people can identify a number on the keypad blindfolded. So, whatever the language or symbols may be, they need not be a hindrance for you to recognise and enter the correct number.

Finally, one more thing.
Did you know that you could also buy the full app?

So, how would a paid version of this app benefit you?

Simply put, in two lines:
1. No advertisements, whatsoever, forever!
2. More colorful themes for your Sudoku grid.

Note:
Your ideas for more colorful themes are most certainly welcome in the comment section.

Hope you enjoy this game, and do not forget to leave a feedback.

Thank you very much.
