Trash Zapper Blasternaut uses math to generate the
tractor beams needed to collect the trash. For every problem answered, a tractor beam is added and, after five problems, a noneducational firing session begins, in which the user tries to collect as much of the trash as possible. Once the firing session ends, the user is presented with more math problems, and the process repeats until all the garbage has been collected. The setting of this level can be changed to one where the trash constantly floats in front of the spacecraft, and the user has to quickly solve the equation in order to capture the trash before it disappears from the screen. Notably, the mini-game uses the "Door Swoosh" sound effect from
Star Trek: The Original Series as the sound effect for successfully collecting a piece of trash.
Number Recycler down. Blasternaut goes down to the fuel chamber to recycle the trash. Here, the player completes equations, at which the machinery of the Number Recycler melts the garbage, freshens it to maximize energy and loads it into the fuel tanks. The player can adjust the numbers and symbols as needed.
Cave Runner Having fueled the tanks, Blasternaut tracks the Trash Alien to a series of caves. By means of a
jetpack, he must fly to the surface of the planet in order to reach the villain. Every level of the cave contains a gap with a number or a mathematical expression on both sides, which form a barrier that Blasternaut can only pass through if he bears a number that comes between the two numbers or the numbers that would be formed by solving the expressions (example: if the gap has "3" on one side and "6 + 3" on the other, Blasternaut's number would have to be between three and nine for him to pass through). Large drops of water, which contain an
operation followed by a number, form on
stalactites that will allow Blasternaut to change his number by implementing the drop's number, through the drop's operation, on his number (example: if the drop reads "+2" than his number will be increased by two). Unless the user is on level one, the caves also contain additional obstacles in the form of
bats,
spider webs, boulders, and large cave-dwelling aliens. In the corners of each such cave is a treasure chest. The user must answer a problem to open the chest and acquire a weapon to drive off the obstacle (example: a
flashlight drives off the bat,
scissors cut the spider-web, etc.). A hammer breaks the boulder and bug spray makes the cave alien cough and disappear.
Math Blaster The last Blasternaut's task is to enter the Trash Alien's
flying saucer and rescue Spot. In order to do this, he must fly through one of four openings in the flying saucer, which contain the answer to a particular problem. He must choose the right answer and reach it before being shot by the Trash Alien's weapons or being struck by flying garbage. In addition, he has limited time before the problem changes. If he is successful, Spot is freed, and the Trash Alien's craft is destroyed, though the Trash Alien escapes. ==Subjects and leveling==
