Live Mathletics Challenge 1

the author of this app says:

The educational team at Mathletics have put together a new game - Live Mathletics Challenge - where you can no challenge your friends and colleagues in Live Mathletics battles where you can now compete directly with your friends via Bluetooth!

If you have OS 3.0 or above on your iPod touch or iPhone, you
can now play peer-to-peer with people near you. One person
creates a game and up to three others can join in.

There's no need for internet access, so you can compete in
the playground or even on the bus or train!

Note that all players need to have OS 3.0 or better to play, which is a free upgrade for iPhone owners. iPod touch users can purchase the upgrade through iTunes.

Requirements

Requires iOS 3.0 or later
