In Hoop de Loop you want to collect as many jewels as you can before you run out of time. Create jewels by colour matching three balls or more to create chain reactions in a moving train. The longer combos you make, the more valuable jewels you get. Make sure to clear the balls before the train reaches the Volcano to avoid game over. Get all the jewels in the front of the train by activating the Collector. Timing is essential!
