$50 in a week? You can go buy a 'AAA' title game and enjoy it for years! This game? $50 is a fart in the wind by comparison. Please remember, you're paying real money to lose fake money, and the end result is you will lose it all while investing more real money into the game. I spent $50 in the past week trying to help my club win, and I had billions of chips before they were lost in a handful of spins. When I first started playing years ago, they were fun, the games felt balanced, and even though I lost a lot, I still won often enough that it was an enjoyable experience. You might get some of them back, might not, and even if you do, they'll wait days to refund them to you so you spend more real money getting fake chips to keep playing.
So say you spent $20 on 222,000,000 chips, and lost them all in a few minutes on a slot (it's very easy to lose that much that fast). Oh, they insist you can win them when you get a special, but once you've lost all your chips, you'll find that in the small print only certain situations merit getting any of those chips back.
