6 by 6 is the hardest level I LOVE this game on my desktop - it features unique colors for each number and also comes in symbols and alphabet. The Android app only has 4 by 4 and 6 by 6. When it comes out for Android with 9 by 9, I will re-download.
Really like this app running on Samsung Galaxy 2.0 7 inch. 6x6 is good for me. 5 Graphics are excellent, so happy to give 5 stars. Also 4x4 good for my grandchildren.
Alan Price Good game but too easy. Bring on the 9x9. Like to see the jigsaw sudoku too
Depends on Adobe Air I don't have and don't want Adobe Air. Why isn't the dependency stated in the app description?
