Bricks

Objective of the game: Shade several cells in the hexagonal grid while following these rules:

Each shaded cell must have at least one shaded cell below it (unless it’s on the bottom row).
There can’t be 3 or more consecutive shaded cells in a horizontal line.
A number indicates the amount of shaded cells around it.
Cells with numbers cannot be shaded.

This genre was invented by Nikoli under the name Tawamurenga.
