GraviTrax: Looping (multiple)

Add a dose of adrenaline to your GraviTrax circuits by sending your marbles through the loop! Give speed to your ball and help it to cross this spectacular obstacle: thanks to the centrifugal force, your ball remains pressed against the rail, even upside down! This action block is played with at least one Starter Set and can then be combined with all GraviTrax elements.
