Don't add it... does good at the beginning but, eventually it will take all your credits so you can buy from their store, and if you complain they respond with their script "that it is a game of chance" but, it isn't. They control your boosters and you lose more than you win this game used to be fun... they have side games that they make impossible. Ingredients for recipes and impossible because they do not come out as they should. Again they control everything nothing fair about this game.
