Ring Dash is game where main objective is to rotate a circle to make sure a disc inside it doesn't touch the wrong color. The game is set up with a circle that has different colored sections, and a disc that is placed inside the circle.

The player must rotate the circle quickly and precisely to make sure the disc stays away from the wrong colored sections. As the game progresses, the speed of the disc increases, making it more challenging for the player to keep up.

The disc is free to move inside the circle and bounces off the sides as it moves. If the disc touches a section of the circle that is the wrong color, it will be destroyed and the player loses the game. However, if the disc touches a section of the circle that is the correct color, it will bounce back and continue moving.
