A hexagonal grid is a grid formed by a tessellation of regular hexagons. Boards made of hexagonal grids are often found in strategy and role-playing games. This is useful because, in contrast to square grid and triangular grid boards, no two hexagonal cells meet only at a single point; touching cells share a common side.
In tiling and board contexts, the hexagonal grid may also be called a hexagonal lattice. However, in point lattice and packing contexts, that term usually denotes the triangular lattice.
The graph formed by the corners and sides of the hexagonal cells admits a brick-wall representation.
