3-in-1 Track Racing (LEGO 10478)

About this set

This is LEGO DUPLO 3-in-1 Car Track Racing, set 10478, with 111 pieces and a difficulty of 2/5. It sits in the vehicle category as a track-and-slide car build, and the model includes a slide, track, small car, archway, flag, trophy and buildable pillars. The color mix covers green, yellow, pink, purple, white and orange, giving it a bright preschool look. For assembly, I would stand up the buildable pillars and archway first, then lay the track and slide sections, and finally add the car, flag and trophy, which cuts down on repeated handling of the track pieces. The clutch is standard DUPLO, so the real tricky part is lining up the track with the slide and keeping the slope consistent as the pillar heights change. It suits preschoolers building with an adult, and parents looking for a first track-style vehicle for a younger child; older kids used to standard LEGO bricks will find it on the easy side.
