I give it 2stars. It is an fun game but however the algorithm they have on this game is so repetitive. I have played this monopoly slots game for about 5 months. Yes there is in app purchase. When I 1st started playing I didn't purchase anything. I started off with what the game gives you. They will let gradually build coins up, but eventually you will stop winning until they get all of your coins back which it will lead you to buy a coin package which are not great deals. Greedy developers..
