Here is a new type loosely inspired by Inaba Naoki’s Cell-Land.
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.
All of the puzzles can be found organized in this printable PDF, or in the images below.
