Intelligently designed "Clever Click' Spiral Domino Ball Track system from Haba, Germany. The system allows easy connection of the track pieces while ensuring maximum stability on the floor and on the higher columns. Created with colourful special effects in mind, the 33 piece Spiral Domino Ball Track includes a track piece with steps, so depending on your set-up, the domino pieces can fall either upwards or downwards in a rainbow surprise! Send a ball on it's mission to knock over the first set of dominoes, then watch as they propel the second ball rushing around the curve to collect the larger set.
