Way too many different things to learn quickly, you have to put some thought and effort into playing. 3 bad things... 1) when you get stuck in a losing streak, you will be stuck there for DAYS. 2) if you are low on coins, you will have to make a purchase, you cannot play yourself out of the hole in this slot. 3) you have to constantly pay to unlock everything, if you don't pay frequently, you will lose playability very fast
