In '''Alien Addition''', Space Invaders meets addition. Five alien spacecraft appear at the top of the screen and approach the player's laser cannon that sits at the bottom of the screen. The unique difference between regular Space Invaders and Alien Addition is that the alien spacecraft display an addition problem, and the player's laser cannon displays possible answers. The player needs to line up his/her laser canon beneath the alien spaceship that displays the correct addition problem for the answer his/her laser cannon corresponds to. If the player correctly aligns his/her laser cannon with the spaceship displaying the corresponding addition problem and shoots, the alien craft is destroyed. It the player shoots a spacecraft with a problem that doesn't line-up with the laser canon's answer, the alien craft falls downward quickly. It's imperative, therefore, that the player act quickly, yet accurately in order to survive the alien onslaught. Alien Addition is suitable for players in kindergarten through sixth grade.

An arcade game format provides fun and challenge while increasing math skills in addition of numbers from 0 to 9. Suitable for children from kindergarten through sixth grade.
