Enough pop-ups to choke a donkey. If you don't link to Facebook, pop-up. If you don't invite a friend, pop-up. Every time you run out of spins, pop-up. Coupon? Pop-up. Event? Pop-up. Contest? Pop-up. And they appear all at the same time every time you do anything. Half the game time is just closing pop-ups. Opening the game without being linked is a minimum of 5 pop-ups back to back.
