Once I had learnt the tricks to playing this game and coping with wait times , I was addicted. The graphics and music are pleasing and apart from a couple of very tiny but seemingly persistent bugs the gameplay is fun and relatively challenging. A lot of players seem to get to a particular point in the game and begin to find it frustrating, my advice is change the way you play (slightly) and perservere - the pace soon picks up again. I have not yet felt the need to spend any real money and in general I usually do not like repetative HOS games but I honestly love this one
