I had originally given this game 5 stars until today. I was playing in the most recent event, "Windy Island" up to the very last hour I was in second place then all of a sudden a gamer in one hour jumped all the way to first place (from 3000 points to 8000) that's when I realized that the events are hacked. Also, just for participating in social media, I would receive free energy now; only 10 people win. I didn't mind the ads since I knew what I signed up for.
