The ads to get free coin must be generated on occasions you guys decide to give em out because mines don't appear everytime I play which is why I won't play as much but definitely crazy to spend money on slots you don't win real dollars for.....unless your to young to get into the casino even then kids save your money for something else like this app but some of the games literally are just there to take all my coins like the old slots I have never seen in any casino
