Using this Hot Wheels set is super easy. First, place the track set on a flat surface. Then, take the included Hot Wheels vehicle and drive it up to the motorized booster. The booster will launch the car to the top of the track and keep it racing around the spiral until it might crash in one of the three crash zones. If you want more fun, you can add additional cars (sold separately). You can store up to 6 cars on the battery box staging area. Remember to use the correct batteries for the motorized booster as specified. Keep the track clean from dust and small debris to ensure smooth racing. If the car seems to move slowly, check the wheels for any blockages. This set is for kids 5 and older, so adult supervision might be needed for younger kids to ensure safety.
