At Level 10 in SimCity BuildIt, two more Specialisations are unlocked for the user - Education and Transportation. This is the first time the user will need to use Golden Keys to buy buildings. These are also the first buildings that are not essential so Sims will not abandon their homes if there is no Education or Transportation. They will be happier and the population will boost if they are there. At Level 15, the Beach is unlocked. Beach specialisation buildings act the same as Education and Transportation but they can only be placed on unlocked Beach areas.
