Customer Reviews

Great fun game but...

I love the build a lot games. They are so fun and entertaining. Two complaints 1 if you pay for a game the ads need to go seriously! And 2 specifically with this version I've gotten stuck on several levels where no lots or houses come up for sale. Very frustrating when you've wasted your time getting so far to just have to start over. Fix please!!

Love these games

Loved the build a lot series for quite a while, but I do wish they weren't so pricy. Especially when moving to a new device. This game, compared to the rest is quite challenging. I would also love a true casual mode with goals, but no endgame, and maybe a larger neighborhood to work with. I also feel if you're going to charge 5 bucks for your app, get rid of the ads.

Aggressive pop ups

Fun game but the pop ups are really annoying. If I've paid for a game I don't want to see ads.

*update* The pop up ads are even worse! Meaning, I have to exit out 3 times to play the game I PAID for. I happily pay money for games that are good. In return I expect the gaming company to respect its customers. Well G5 blows. They clearly only see $$$ and could give a rats behind about its paying customers. I'm glad they litter my page with ads for other I know which ones to avoid.
