In Mergedom, your primary goal is to earn stars to renovate and design your rooms.
You start on Level 1, with 100 Energy and 2000 Gold. You can earn stars by completing your orders and use the stars for the renovation of your rooms.
By merging the same items, you can create high-level ones and deliver your orders. You gain experience points once you complete a room, and you can level up when you have enough experience points.
You will also earn chests from leveling up, and chests are the essential source of the new items.
