Ok in Fragger they had one full paid version which had all the worlds. They had two free versions which had one world each. I don't think you could get ALL the Fragger worlds for free so you missed some levels by not getting the full app. But with multiple downloads you could get MUCH of Fragger for free.
SO, my theory is that is is the first world only and if you want the all the levels you need to get the full.
