Do not play this game if you have auto-pay, or it will cost you a fortune. The amount of pop-ups is almost comical. It's almost a game in and of itself trying to touch on what you are trying to touch on before a pop-up gets in the way. And the pop-ups aren't for just a dollar or two, they will cost you $60-$100 if you accidentally click on it. The game is fun, and the physics are pretty accurate, but the amount of pop-ups ruin the game.
