first time you log in, game gives some chips for free and supposedly a high chance rate in games for a couple of hours. You hit some jackpots and eventually "luck" wears off and you run out of chips. And then the only chip source is from log in bonus every 5 mins which is a very small amount. So now you have much worse "luck" compared to start and rely on the very small amount of chips the game throws at you. Oh and yes you can also purchase them. Takes your time and gives back almost nothing
