Dragon Mix is a math learning game for the TI-99, where players control a large dragon defending a city on the right of the screen. Math equations represented by spaceships quickly approach from the left, and an answer appears on the dragon's belly. The goal is to shoot the spaceship that has the correct equation.
Gameplay involves shooting spaceships that have mathematical equations written on them, with the correct one appearing on the dragon's belly. The player must act quickly before a spaceship gets too close to the city, which will be destroyed if it happens three times, resulting in game over and the final score being displayed.
