App Description

Improve your mental math! Mess with your friends' faces! It's a unique, silly and - believe it or not - educational two-player game!

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!

Number Battle is fully playable for free and this new ad-supported version now includes these full game packs for FREE:

- 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 now included for free for all users!

- Spooky pack
- Pirates
- Animals
- The Holidays

Also check out "Vocab Battle" by the same developer if you want to play this game to improve your SAT Vocabulary or study a foreign language!

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!
