Here is a new type loosely inspired by Inaba Naoki’s Cell-Land.

### Rules

Shade some cells such that:

- Numbers indicate exactly how many surrounding cells are filled.
- Filled cells must be in clusters of 3, forming trapezoids. A trapezoid may not share an edge with another trapezoid.
- All unfilled cells are connected edge-to-edge.

### Example

### Puzzles
