Use your mouse to select which grade from K-8 you’d like to play as and then choose which skill within that grade you’d like to test. When the game begins there is an unsolved math equation complete with four multiple choices beneath it. Your job is to select the correct answer using your mouse. Each correct answer will result in a successful attack against the invading aliens. If you fail to answer correctly, the aliens will continue to smash into your planet, slowly decreasing its health until it is inevitably defeated. Each alien ship you successfully shoot out of the sky is worth money. After a round ends you’ll be able to use that money to upgrade your ship abilities, your planets defense, ort to add a drone canon which will take potshots at the aliens for you. Be judicious with your upgrades, they may be the key to victory.
