For starters there are 8 pop up ads everytime you start the app. Then many more as you go Pretty sure game is rigged. Amazingly, after getting free coins, someone will want to double and then get multiple doubles in their dice. Seems to only happen to people that have 50k or more in coins. Basically, if you pay, you are guaranteed to win unless you play against someone else paying. And while I don't pay so I don't know, for sure, I suspect you will then lose to people that pay more than you do.
