Another building in the EU is now ready to be updated in the Cityville Game. The upgrade of the museum can be started, beginning with the collection of profits from all the museums you have and then clicking on the image when you see the big blue and green arrow hovering over it.
Here you can see the building from the list of ingredients needed to collect to improve. Yes, unfortunately this is not an easy task when you only have to ask your friends to join the team and do you really need to collect a series of 15 articles, some of which you already have. It takes three each of marble, windows, display lights, ribbons and velvet ropes.

Once you have collected all the documents, change your museum in the size and visual design, and will then also the possibility of up to 400 people can live in your city instead of just your 300th museum will be also release a random chance for you to win marble every time you collect the building.
But I do not think your work is done for now, as you can upgrade your museum on Level 3. This must be at least level 20 and have 2,500 or more inhabitants of the city. You need time to gather another set of five ingredients to improve the construction and once completed, will finally be able to put the hammer and chisel. The museum will support 600 people, and the opportunity to receive Marble increase.
Although this seems an update round, which forced him to spend marble and other objects to improve a Cityville Game building just for you to win this new marble, I guess it gives you something to do if you get caught in all missions, or simply you like the look of the level of the museum. Anyway, do not feel pressured to complete these improvements if you have other things that would make use of their applications a day for the site.
