# Building Grades

Each [famous building](https://city-whitepaper.gitbook.io/reality-rush/advanced-gameplay/famous-buildings) in **Reality Rush** has a grade, starting from the base value represented by the red color. Building grades multiply the points generation from both tapping and passive income, significantly boosting the growth of your city.

### Merge System

<figure><img src="https://2731102634-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FQtoQsuvL0tQaT2Cf2qfM%2Fuploads%2FXc6LqFnx8GZ05jAttLGa%2Fiphone15pro-6.png?alt=media&#x26;token=c38416dd-dac7-4188-8c08-4eae1ba3aaa6" alt="" width="188"><figcaption></figcaption></figure>

To upgrade a building to a higher grade, you need at least two buildings of the same tier and the same grade. These buildings do not need to be identical, but they must have equal value. For example, you can merge a rare Eiffel Tower (Tier 1) with a rare Statue of Liberty (Tier 1), but you cannot merge buildings if their tiers and grades differ.

#### Merging Process

The merging system requires only two buildings of the same grade to level up. The progression is as follows:

* **2 Base buildings (Red) → 1 Uncommon building (Green)**
* **2 Uncommon buildings (Green) → 1 Rare building (Blue)**
* **2 Rare buildings (Blue) → 1 Epic building (Purple)**
* **2 Epic buildings (Purple) → 1 Legendary building (Orange)**
* **10 Legendary (Orange) -> 1 Artifact (Gold)**
* **10 Artifact (Gold) -> 1 Titan (Platinum)**
