Crazy Cake Swap will try and entice you into putting your hand into your pocket to spend real money on diamonds which is the games premium currency. This is because the game runs a life system which restricts you to five attempts after which you are forced to wait until your health is restored. When you reach the end of significant chapters you will only be able to progress to the next set of levels by using diamonds, asking your friends or by completing three additional challenges which can only be attempted once every 24 hours.
