Sudoku1Astraware’s Sudoku for Android is an app for true “Sudokuphiles”. I say that not to imply that only a true Sudoku fan would agree with the $4.99 price tag it bears on Android Market, but because a true fan will appreciate the wealth of features and controllable settings built into the app which are not available, to the same extent, in most other Sudoku apps.

For those who don’t know what Sudoku is (or those who haven’t browsed through a newspaper in the past few years, or have managed to avoid the impulse item section in every supermarket, bookstore, and airport nationwide), Sudoku is a logic-based game in which you fill a 9×9 grid with numbers so that every row, column, and 3×3 sub-grid contain the numbers 1 through 9 without any repeating numbers in each respective section.

Astraware’s Sudoku includes your standard features such as pencil marks (smaller numbers appearing in the corners of each square for when you’re unsure or have narrowed down to a few possibilities) and the ability to undo or start over. However, where Astraware’s version really shines is in its ability to control every adjustable setting of the game, such as whether to allow, forbid, or flag incorrect entries, or choosing from six levels of difficulty. If you’re stuck, you can choose whether to reveal the answer to a random cell or to simply highlight an area on the grid which can be completed more easily. New to Astraware’s Suduko is an impressive “hold and highlight” feature which highlights all cells filled with a particular number of your choosing and all parts of the grid in which that number cannot be entered.


You can play from the pre-loaded puzzles or download new puzzles from Astraware’s daily updated server. Find a printed puzzle that has you stumped? Enter the numbers in a new puzzle and Astraware can offer hints and assistance to help solve it.

For $4.99, Astraware’s Sudoku may not be for everyone. A novice may, understandably, choose to try out one or some of the many free apps available on Android Market. However, few Sudoku apps offer the same amount and degree of settings, puzzle assistance, and control as Astraware’s Sudoku does.

  • This App Was Tested Using: T-Mobile Motorola CLIQ on Android 1.5
  • Presentation: Interface is more functional than aesthetic; not quite as easy on the eyes as the iPhone version.
  • Value: Astraware crams in a ton of functionality and configuration, but ultimately its a simple game with a few basic operations that many free apps include.
  • Stability/Resources:  Crashed repeatedly while testing on myTouch3G running stock 1.6. However, had very few problems when testing on Motorola CLIQ. The only issue I was concerned about was that every time I opened or closed the slider, the app force closed and re-opened (with game saved).
  • Bottom Line – Probably the best paid Sudoku app currently available on the market, but hard to find the value in it when Android Market has an abundance of quality, free offerings.

  1. I loved this app for my treo because I was able to draw xy-chains to solve diabolicals. The Droid needs a capacitive stylus, with a real nib, and then maybe you can update this app to have the drawing overlay screen. I just don't enjoy solving Sudokus otherwise. I wish I could still get new puzzles on my networkless treo. I love my Droid but it's killing me that Astraware's app for it cannot compete with the Palm version.

  2. I just got Sudoku Adept, and so far I think it may be the best of the ones I have used.
