In Tower Up you own all the residences in a huge tower. You're hoping to upgrade your apartments and condos and penthouse suites. You cannot do that without money though. Get different achievments but you have to be on your toes because the residents will be very demnanding and need something every second of the day. You can buy new floors that will serve food or serve as dormitories for your residents. Hire people to serve the food and be sure to collect money from your sales so you can further make upgrades to your tower in Tower Up!
