Summary: If your device is running OS 3.0 or above, you can try out the new Live Mathletics Challenge app which allows you to challenge your friends via Bluetooth! ******************* Mathletics has brought their world renowned maths game to iTunes! For the first time you can play Live Mathletics from your iPhone or iPod Touch just the same as you do at home or school. Choose from 5 levels of difficulty ranging from simple addition to 10 to a combination of patterns, multiplication, division and subtraction. If you have a WiFi/3G connection available, you can choose to play against other Mathletes from around the world in 60 second challenges answering problems in a multiplayer* game environment. This app is constantly being updated – as you know – the Team from Mathletics is always working on something new! NOTE: If your internet connection is coming through a proxy server, you may not be able to play multi-player games. We are looking into this, and hope to have a solution asap. * WiFi/3G connection required for multiplayer games.
