Buildings are locations that can be found on the Main map, like the Villa, the Farm, etc. As you progress through the Mahjong levels inside the buildings, you will find collection resources and other useful bonuses.
Buildings can be locked or unlocked.
- Unlocked buildings are ready to go. You can complete various levels in them.
- Locked buildings are areas of the playing field with locks that display the level needed to unlock them. See 'How can I unlock new Buildings?' for more information.
Every building has a rank from 1 to 8, which increases as you beat Mahjong levels. This also affects the levels' difficulty.
