Numeraders is a simple but challenging game inspired by Casio Calculator games from the 1980s.
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 shoot 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!
If you enjoyed tapping out numbers on your Casio Calculator during school in the '80s - then this is for you!
