Rules of Tatami

Split the grid into subrectangles, so that each subrectangle contains exactly one marked cell. 

It is not allowed for four subrectangles to meet at a point.

This marked cell indicates how the dimensions of the subrectangle compare. If the subrectangle is longer than it is tall, the marked cell should be marked with a horizontal line, whereas if it is taller than it is long, it should be marked with a vertical line. Finally, if the subrectangle is square, the marked cell should be marked with a plus.

Rules for Country Road

Shade some squares and draw a continuous path through the rest of the squares so that:

• The path goes through each region exactly once.
• Any numbered cell contains exactly that number of squares on the path.
• No two shaded cells lie directly across a region border from each other.

Rules of Mochikoro

You are given a grid with numbers in some of the cells.

Shade some of the cells dark, the others remaining light such that:

• All orthogonally contiguous areas of light cells are rectangles with sides parallel to the sides of the grid.
• There are no 2 x 2 areas of dark cells
• You can get from any light cell to any other moving only through light cells which are adjacent orthogonally or diagonally.
