Fun but Limited. This game pushes pay to play. Cards are very expensive and play time is limited without cash. The kicker is, even you you divi up cash, it does not guarantee what you need to progress. For instance, you can convert gems for coins. When you purchase a pack of coins there is not a guaranteed amount per purchase. You can receive 500k to 1.5 million coins. Normally players will get the short hand of the spectrum. Fun, but a painfully slow crawl.
