A ton of games use psychological tricks to get people to spend. Look at hearthstone from Blizzard. You have to keep buying cards until you get lucky... and you never do. The randomized fashion makes it so you never stop spending even though you are one card away from your ideal deck. It has all the elements of gambling minus the real life rewards. There definitely needs to be some sort of regulation — perhaps punishing the randomized reward mechanics.
