The action stone Speed Breaker brings another decelerating element to the GraviTrax marble run world.
The Speed Breaker picks up the ball, transports it down and sets it down - no matter how fast the ball rolls towards the action stone, when it reaches the bottom, each ball rolls out at the same speed.
Thus, different levels are connected in a new and very practical way.
At which points in the marble run does it make sense to brake the ball a little?
