There are many apps for kids about cars, but most of them concentrate on building the car or on painting the car or adding extra wacky accessories to the cars. You might be able to drive the cars around a pre-determined track or you might drive on an imaginary road trip, but to the best of my knowledge, this is the first car-related app for kids that encourages kids to spend time building the road and that's really interesting! How will the vehicle respond to driving on bumpy roads? Or roads with steep hills? Or lots of twisty curves? What if we throw in some imaginary stuff like teleporters or superfast conveyor belts or super bouncy whoopee cushions? What if we do change up the car? What if it was a monster truck instead? Or a tractor? Or a bulldozer? Or even a horse? There are so many different options to explore that they didn't want to overwhelm first time players, so they've designed the app so that when you first encounter it, you have only a small number of options, but as you play, you earn stars and those stars add up to earn you new parts for your road and new vehicles to try out as well. The app is free to download, but if you want to be able to use all of the unlocked items, you'll have to pay a one-time in-app purchase to access the full set of game elements. Sort of like "Minecraft" but with cars, your 6-8 year old child will likey love this one.
