Theme: Anti-symmetrical Pinwheel

Rules: The challenge is to draw a single loop, without crossings or intersections, subject to the following rules:

Bordered unshaded cells and shaded cell do not form part of the loop.
Bordered unshaded cells must be inside the loop upon completion.
Shaded cells must be outside the loop upon completion.
Numbers sum the length of the loop segments in a given direction, each cell border crossed in that direction represents a count of one.

Theme: Half colour, half wild

Theme: Big squares, little squares

Rules: The challenge is to light up all white cells, subject to the following rules:

Each region contains exactly one light bulb.
Each light bulb illuminates all white cells in a horizontal and vertical direction until the beam hits a black cell or a wall.
Light bulbs cannot shine on each other.

Theme: Crossing that gap

The objective is insert numbers, subject to the following rules:

Each area must contain at least one numbered cell.
Numbers in some cells count the total of numbered cells in that area.
Where two numbers connect across a boundary between areas, those numbers must be different.
Numbers must form one connected area with no 2x2 areas of numbered cells.

Theme: Parquet

Theme: Pyramids

Rules: The challenge is to shade some cells, subject to the following rules:

All shaded cells must eventually connect, but must not form 2x2 areas.
Numbers on some cells indicate the number of consecutive shaded cells around that cell, if there is more than one number then there must be at least one unshaded cell between the shaded regions, "?" is wild and can stand for any number between 1 and 8.
Clues also indicate the length of shaded cell groups in its region. Regions without clues have no restrictions.
Cells with numbers can never be shaded.
