Game-games strongly resemble turtles with a red-orange shell, blue skin on their heads and feet, and flat grey feet.
In Sonic the Hedgehog 2 (8-bit), Game-games are featured in Sky High Zone and Scrambled Egg Zone. Here, they either walk back and forth on slopes or stand still. As Sonic approaches one though, the Game-game rises up into the air and flies horizontally over him like a Frisbee.
The Game-game's Frisbee attack can only damage the player while Sonic is jumping into mid-air. Otherwise, they can easily be defeated by performing the Spin Jump. Like the other Badniks in the game, they do not contain Animals.
- Game-game is a play on the word "Kame" (石亀?), meaning "turtle" in Japanese.
