Horrible. The game itself is fine but what are you thinking with the ads? I don't mind ads - I get it, they're the reason we can play free. But I've never seen them used like this. Every 5 - 10 seconds - really? No matter where you are in the game? Over & over non-stop. Sure you're given a "reward" each time but you can keep them-not worth all the pauses. Put them between games or space them out more. This is no game. It's 1 continuous ad interrupted by a game for a few seconds here & there
