This application is an adapted version of the classic SOS game for Android. SOS game is a brain puzzle game like the classic XOX. SOS game has a bigger board. You can play against your Android device in single player mode. You can also play with a friend in two player mode.
When you finish the game in single player mode, the score is sent to the online scoreboard on Google+. You can see the best players daily, weekly or for all times.
If you do not prefer to sign in with Google+, you can still play the game in offline mode, but your score is not submitted to online scoring in this case.
Good luck ...
