Make your cities grow and glow in this energetic hit!
You already know how to construct homes, malls and restaurants, right? Now it’s time to invest in green energy! Build solar towers, wind farms and even nuclear power plants to make your cities sustainable and prosperous for generations. Watch out for blackouts, though, as building too fast can result in a system overload. So take it slow, plan ahead and manage your energy resources carefully. Be ready to rethink your property layouts and infrastructure, or even start over from scratch. To “go green,” your neighborhoods need eco-chic shops, solar-heated swimming pools and more. Do whatever it takes to build the most energy efficient city in the world!

Good game

I like this game just have a problem with the screen going blank and have to re download it to play. Then I have to start at the beginning again! This is my 4th time trying to finish the game. So obviously I like the game just wish it would quit going blank. Then it doesn't always sale you the houses so you have to restart that level! If these things were fixed I would give it a 5 star rating

Building Fun!

I've played all the Build-A-Lot games and loved EVERY one. This one is by far the most challenging for me. This type of game is EXCELLENT for senior citizens interested in preserving their mental acuity and focus. I wish there would be new games designed in this series for IOS.

More challenging than earlier versions

I have enjoyed all of the versions of this game all the way back to when I was playing the original on a desk top. I do get stuck more often on levels in #4, but I still have fun. And really happy to be playing it on my iPad now.
