Not worth it. Too many issues. I had a high level in the game and the rewards are too low. At one point, I had about 3 trillion coins and the one if the goals is to bet 26 trillion. I understand it is a casino style play but it is ridiculous when you spend 2-3 trillion coins for nothing. You rarely hit anything but the mini jackpots. Play something else. I am about to un-install the game. No point in wasting any more money and time.
