One day, Plankton is reading a newspaper and sees a advertisement saying: "Glove Universe presents glovies build-a-game contest! Grand prize: 5,000,000 something." Plankton thinks its money and decides to build a game using Karen's help. The object of the game is to hit the characters on screen in order to meet the number goal before the time runs out. If you haven't hit enough characters within the time limit, you lose. If you meet the number goal long before the time runs out, you can keep on playing to earn stars. If the player reaches 3 stars before the timer runs out the level ends. Be careful when hitting the character(s). Certain characters require specific hits. If you use the wrong hit, you'll lose time. You can also use power-ups to help make it easier. The game ends when fail to complete the goal or you beat level 20. In the ending, Plankton gets the grand prize of 5,000,000 free rides at Glove Universe.
Each character requires specific hits. For SpongeBob you swipe the mouse over him, for Patrick you must click once, for Squidward you must double click on him, for Mr. Krabs you wait for him to stop counting his money and then hit him, and for Gary, you hit each number in order.
You can click on the ice cubes to freeze the characters for a short time.
Cutscenes in this game are done through comic strips.
A "six weeks later..." time card is used 4 times in some of the cutscenes whenever one of Plankton's game machines get destroyed and repaired. This implies that the glovies build-a-game contest went on for a total of 168 days or 5 months.
