Except the sorting history LITERALLY says the restGood Hufflepuff , she took the restand taught them all she knew , <| sep |> Not paying taxes ? <| sep |> An hour of cottoneyeJoe on loop . <| sep |> Simple answer , gambling with a side of time investment . Longer answer A lot of things newer players buy are scrolls . They ' re gambling just like anyone in a casino . Their payoff could be huge with a Nat 4 or 5 that could carry them hard and make them happy . Or it could be small and just give them fodder . Most people I know that spend money don ' t really buy scrolls anymore though , usually Devilmon or Transmogs as those are things that are either time gated or almost impossible to get simply by farming for them . Another big thing is most packs come with crystals , which people can use to extend the time they play the game in one sitting . Look at a game like Dota 2 . Completely free to play , only things you can buy are skins , music packs , HUD ' s and courierswards , etc . None of them offer any real benefit , they just look nice . And yet they raised an over 20 million dollar prize pool of profits from sales .
