Numeraders is a simple game for the iPhone/Touch inspired by Casio calculator games from the 1980s. If you remember walking around your school yard with a calculator in hand tapping keys to shoot numbers - then this is for you!
You must cycle through the green targeter number on the left using the Aim button and match the advancing red numbers on the right. Tapping fire will destroy the invader and gain you 10 points.
If you shoot a sequence of numbers which add up to 10, you will gain a 'n' character - which is worth 150 points when you shoot it. A free life is awarded at every 10 levels - so good luck!
