Love playing this game! Loads of fun & works your brain real well. The developers are on the ball for the most part. If there is a problem, they diligently work to fix any & all gliches. Usually within 24 to 48 hours, awesome! I have been playing this game/app daily for over 3 years and have almost reached level 400 & nearing the end of the greeks. I like how you slowly go through the decades of history to help different people with everyday tasks. I recomend for anyone to enjoy playing daily!
