This product is a FREE app that works on IOS, Google Play, or as a Facebook game for Mac or PC. I actually added it as a Facebook game. There are additional costs if you want to purchase more coins, etc. but you can start it off and play for free without having to purchase anything.
While this game is intended for adults (and specifically I note the fact that your child could accidentally make a purchase if your computer isn't set up correctly), my five-year-old daughter, Abigail, was actually the biggest lover of this game in our family. I snagged a video of her playing the game which you can watch below:
