Using the Hot Wheels 4-Loop Crash Out track set is super easy. First, unfold the set and set it up in a flat area. Place the included 1:64 scale vehicle on the track and turn on the motorized booster to get it moving. You can add more cars (sold separately) to make the race more exciting. Remember, the more cars you add, the higher the chance of a crash! When you're done playing, fold the set for convenient storage. Keep the track clean and free from dust or small objects that could interfere with the cars' movement. If the booster isn't working properly, check the batteries. And since colors and decorations may vary, enjoy the unique look of your track set. This toy is suitable for kids aged 5 and up, so make sure younger kids are supervised during play.
