Same as every other slot game. Increase odds in the beginning but you will lose it all to force purchase! The funny thing is the amount of work they put into their adds to say they are not like the other ones. So they are even worse for the fact that they lie to you. Devs are not in it to make content worth paying for. Mobile games have ruined the culture of games with nothing but marketing(trickery) to take peoples money for the least amount of work. Good way to kill 30min then delete it!
