I enjoy the game, it nice and simple and utterly brain numbing... Prefect for stress relief! There are lots and lots of adverts, plus you have to complete puzzles by watching advert to get trail balls... I have completed a few puzzles watched soooo many stupid adverts but yet I am still waiting for the trails to unlock. How frustrating can one be? It's just a game that makes you watch 100000s of adverts for absolutely nothing!!!!!!! That is disgusting!
