We saw last week how it was possible to fill in a 7x7 grid according to certain rules, but that there were only two solutions (ignoring reflections or rotations).

Despite being smaller, a 6x6 grid has at least five distinct solutions. Can you find them?

A reminder of the rules

You can diagonally half-shade some of the squares of the grid (shown below in grey).

You can fully shade some of the squares at the edge of the grid, but none in the interior (shown below in black) and if a square is fully shaded no adjacent squares can also be fully shaded.

The regions that remain unshaded must form only diagonal squares and diagonal rectangles.

A solution cannot be simply a reflection or rotation of another solution.

Here is one of the solutions to the 7x7 grid, and five 6x6 grids to fill in:
