Number Battle Deluxe - Mental Math

For the free app, search "Number Battle". This paid version is the full game with no in-app purchases to allow schools to purchase it using the Educational Volume Purchase Program.

The most fun way ever to practise arithmetic and improve your number skills - a rapid-fire battle of comic-style, face-mangling quizziness.

Take or pick a photo and put your face in the game. Then fight it out against a nearby opponent using Bluetooth; or invite your friends online; or find a match through Game Center.

** UPDATED FOR 2014 ** Now includes solo game mode so you don't need to have a friend nearby to play!

Playing the game is simple: answer three questions correctly and you get to attack your opponent's face!

Choose from over 100 items to stick onto the photo, including eyes, glasses, ears and hair - or add a sound effect caption. Use a two-finger pinch to zoom and rotate things to line them up just how you want. See the screenshots to see what a mess we've made of the developers' faces!

When the game is over, you can post a humiliating picture of the loser to Facebook!

Vocab Battle includes the following game packs in full:

- Addition and Subtraction - calculations involving 1, 2, 3 or 4 digit numbers
- Multiplication and Division - four difficulty levels, for multiples of numbers up to 20

The following themed sticker packs are also included:

Please be a good sport. Choose a photo that is a good likeness of you and enjoy the silly things people do to your face when you lose!
