"## How to play

### 1. Basic rules

- Sliding operation: Move all blocks by sliding the screen up, down, left and right.
- Merge Evolution: Blocks with the same number that collide will merge into higher-level elements.
- Goal: Continue to synthesize, challenge higher numbers and evolutionary stages, and finally synthesize 2048 (star core) or higher!

### 2. Element evolution system

Each number represents an element stage. During synthesis, not only are the numbers upgraded, but there are also exclusive icons and animations:

| Number | Element form | Icon |
|-------|------------------|-------|
| 2 | water droplets | ?? |
| 4 | small leaves | ?? |
| 8 | buds | ?? |
| 16 | small tree | ?? |
| 32 | Forest | ?? |
| 64 | sand | ⏳ |
| 128 | Ruin Fragments | ?? |
| 256 | Temple | ?? |
| 512 | Ice Crystal | ❄️ |
| 1024 | Glacier | ?? |
| 2048 | Star Core | ⭐ |
| Higher | Wonders of the Universe | ?????? |

### 3. Skill system

- Reach certain blocks (such as 128, 256, 512) to unlock skills:
- Storm Rearrange: Disrupt the grid but retain all block values.
- Time Back: Go back to the state before the last merge.
- Clear a column: Click to clear an entire column.
- Skills have a limited number of times and can be obtained by synthesizing energy balls or achievements.

### 4. Dynamic themes and achievements

- The leaderboard records your highest score in real time and competes with friends.

### 5. Special experience
