Add Astra

You’re the best arithmetech racer on Earth. But what about everywhere else?

Add Astra is a math game about racing, and a racing game about math, developed by Coincidence. We made it for a client to include in their elementary school math curriculum, but they have graciously agreed to also let us release it on Steam.

Rev up your very own math-pod, powered by addition, subtraction, and multiplication! Adjust the difficulty by playing with whole numbers, fractions, or decimals! Master ten tracks across five galaxy-spanning locations! See many, if not most, numbers!
