I'd definitely avoid it. It's a shame because it's such a good game with lots of content, but the algorithms for minimum bets is so poor, to the point it's not even affordable to buy extra credits. I currently have $4b coins which isn't a lot in this game, but as you build your money up, you have to increase your bet to unlock jackpots. It's this alone that ruins the game. It would cost me $3B each spin to unlock the jackpot features. It doesn't make sense to restrict this.
