Regional Yajilin (also known as "Yajilin (Regions)") is a square or rectangular grid divided into regions. The aim is to blacken some cells and to draw a single non-intersecting loop through all the white cells. A number in a region indicates the number of black cells in that region. A region without a number can contain any amount of black cells. No two black cells can share a border. The loop may visit numbered cells; numbered cells can be blackened.

Sunglasses is a logic puzzle. A rectangular or square grid contains lines ("bridges") in some cells. The goal is to blacken some cells to create pairs of figures (twin shapes). Twin shapes ("lenses") are symmetrical with respect to a bridge. Two lenses may not share an edge. Cells with bridges can not be blacken. Numbers outside the grid show the number of black cells in a corresponding row or column.



Masakuchi is a logic puzzle published by Nikoli. A rectangular or square grid is divided into regions. Each region must be filled with each of the digits from 1 to the number of cells in the region. When two numbers are orthogonally adjacent across a region boundary, the numbers must be different. The grid may contain black cells with arrows and numbers: the arrow points at the greatest number among the four cells around (up, under, left, right) the black cell. The number in the black cell shows the difference between the greatest number and the second highest number in all orthogonally adjacent cells around the black cell.
