A simple and fun way to practice your multiplication tables (1x-12x)! In this game you select a difficulty level that corresponds to the maximum Multiplier of random equations falling from the sky. Target an equation by entering its Product using the game's numeric key pad. If you are correct a missile will be launched which will explode the targeted equation upon impact earning you points equal to its Product. Any equation reaching your City below will cause you to lose points equal to that equation's Product. Equations moving horizontally test your skills by slightly exceeding the difficulty level you selected. Hitting these equations will earn you bonus points by exploding every other equation in the view.

Students in Grand Prairie were given a simple problem during App Development Camp… Hangman just isn’t appropriate for young students in 2025… so how can we engage them in word game play in a similar fashion. These are their responses. Not only did they learn to code, but they learned to solve a problem!
