When I first started I would have given 5 *, however since the updates it is ad after ad after ad. I won 10 free spins and during this time I had 4 separate adverts for other gaming sites. As soon as the free spins ended, yep up came another. You have ruined the experience by having so many pop up adverts during games. Before the game - fine, after the game - fine, during the game - not good. I am considering leaving CTS because of these adverts.
