The popular upgrade to the 173, this model includes a multiple-spiral tower.
With snap-fit parts which are inter-changeable between all models in the series, this fun and rewarding introductory kit also includes a table-top marble game.
Can also be used as an expansion set with all other Techno-Balls editions
Building this table-top helter skelter you must first erect the tower then mount the struts, wind the tracks and span the gaps before taking careful aim at the pinball target...& launching your balls down the run!
Absorbing in it's appeal, this amazing construction kit will amuse and enthrall boys (and girls!) of all ages!
