The buildings don’t have any special effects or functions and are merely markers for your progress toward the next Village.There are 252 villages, each with its own unique theme, that you can complete in Coin Master.
Upgrading buildings costs Coin, and upgrades become progressively more expensive the further on you get in the game, so prepare for a grind. In order to complete a level and advance to the next Village, you must upgrade all of the structures in your current village to 5-star Rating. There are five different buildings you must construct in each level. Villages serve as the levels in Coin Master.
