You can play the game for free without ever encountering any IAP, perhaps that's awful for us money wise but it is good for the game. The IAP in there adds a "full version" of the game that unlocks two additional cards (with more coming), stars which let you swap your entire hand instead of discarding a single card in a turn, a star doubler, and infinite stars in case you get fed up with the concept of stars.
