I like this game

I paid the 2.99 to get rid of the ads so that’s not an issue and it’s free if you don’t mind them. It is a really distracting and fun game. The only thing that I don’t understand is what the coins are for. There doesn’t seem to be anything to “buy” without watching an ad sooo I don’t get it. I don’t use the hints and have about 90 saved up so maybe it’s for that when you run out? I don’t know, but totally fun game.

Too hard

Terrible choices of ads

App was great until today when it showed my 8yo daughter two sexually romantic ads in less than 2 minutes of each other. Really like the game for problem solving nut not happy with the ad choices. Review your ads to make them ok for any age, Fill!
