Circular Grid

Circular grids are an abnormal grid shape, wherein the grid is made up of concentric circles with perpendicular lines radiating from the center dividing the rings into segments. These lines may be continuous from center to edge, or may be staggered (creating more unique straight paths from edge to center than the number of vertical segments present).

These types of grids are commonly used for crossword variations, but has also been used in miscellaneous word puzzles and logic variations.
