Oh my! I just discovered the Carousel of Dreams thanks to this thread. I downloaded the app about a week ago because I thought it said I could earn 50 airmiles for doing so. However, I have not received those miles, so maybe I misread something. Anyway, I noticed the Carousel of Dreams on there but didn't know what it was anD unfortunately have not been playing. However, reading this thread, I thought I would give it a go and earned 50 airmiles (+15+10+15+10) on 4 out of 6 times I was allowed to play.
Thanks everyone!!
