It also has the dragon/tiger themes, just like the original wave of Mighty Cash games they released. I can see why – the game was developed by Gimmie Games, the same Aristocrat division that has been responsible for the various Mighty Cash games out there. I recently had the opportunity to try Cash Xtreme Rising, which a friend of mine had described as a sequel to Mighty Cash (even though there is a previous game series called Cash Xtreme by the same studio).
Generally, Aristocrat has been often the one that is copied by others, but this time it gets a little more murky. As I reported during G2E, slot manufacturers love to liberally borrow concepts from each other.
