About OsXs

OsXs is Frosty Badger's take on the classic game of Noughts and Crosses (also known as Tic Tac Toe) for the iPhone, iPod Touch and iPad.

Playing the game is very simple: each player takes it in turn to place their pieces (either naughts or crosses) onto a 3 x 3 grid. To win, a player must have three of their pieces lined up in a row, a column or a diagonal line. If the grid is full and neither player has managed to do this, the game is a draw.

OsXs can be played single player (against the computer) or with a friend. Single player has two difficulty levels - easy (suitable for beginners and younger players) and hard (you'll have to apply some experience and strategy!). A counter for each player displays the number of rounds won. When the counter hits 10, the game is over and the counter is reset.

OsXs has more than one look and sound! To cycle through its selection of themes, simply shake the device on iPhones or iPod Touches, or swipe (left/right) with two fingers on iPads. Currently there are 4 themes: classic, tech, egypt and blueprint.


11th Sep 2017 - OsXs 1.3 has been submitted to the App Store and should be available soon. We updated the app to 64-bit so it continues to work on new versions of iOS and new Apple devices.

21st Oct 2012 - OsXs 1.2 has been submitted to the App Store and should be available soon. The update fixes a round/game reset bug when running on iOS6 and above.

21st Feb 2011 - OsXs 1.1 is now available in the App Store. The update adds support for iPhone 4 and the iPad, bringing both retina and HD versions of all themes. It also includes a fourth new theme called "blueprint" and a few tweaks and improvements. Enjoy!
