GraviTrax Extension: Color Swap

The Color Swap brings a new element of surprise into the GraviTrax world. As if by magic, the ball changes color as it passes the stone. This can be prepared in two ways. Either by loading the stone with a ball at the beginning or by installing it in the track accordingly. The Color Swap provides a visual highlight through the illusion of color change. How many times can the color of the balls be changed during a run?
