Your only get 5 tickets free to play the first chapter. After that you have to buy more tickets with diamonds. And to get diamonds you have to pay with real world money. Your can get diamonds for free by watching ads but you can only get one at a time. It cost 100 diamonds for one tickets. Thay means you have to watch 500 ads so you can play the game for one more chapter. That will last you for like 5 mins. So unless you're willing pay real world money it's not worth it.
