"Simple Sudoku"

Reviewed by / Jun 07, 2011

Play Sudoku with several input modes

This simple Sudoku has three level options (easy, medium, hard) with 30 puzzles each one. Hints are shown by default in order to help you get familiar with the game, but you can disable them in the settings if you want a more challenging game mode.

There are several input modes:

- Popup: tap any cell with finger to edit its content.

- Single number: First select any number and then tap on cells where you want the number filled.

- NumPad: Buttons act as a standard numeric keyboard. Press Pencil button to toggle cell's note editing.

Roman Mašek is the creator of this Sudoku app. It's his first one so we hope him a long and successful career as a developer. Download if you're a fan of Sudokus and want to do them easily with no need of paper and pen.

    Simple, free, extensible. Doesn't crash or have bugs. Couldn't ask for more.

    I love it. However it needs the ability to sync completed puzzles and times with your Google account, and possibly enable a leaderboard. I hope this can be incorporated.
