[<< wikibooks] Puzzles/Segregation
```Segregation type of puzzle is a type of puzzle that are different from the puzzle shown before whereas the main objective are not filling in the grid buat actually divide out the cells according to its category

== Domino Set ==
Draw lines to separate the grid to form a complete set of standard dominoes (28 pieces) , with exactly one of each domino
A '0' represent blank on a traditional domino
Use the checklist to help track which dominoes already being placed

== Rectangles ==
Draw borders along some grid lines to divide the grid into a set of rectangles, such that each rectangles contain exactly one number
All cells are within one rectangle
The number inside each rectangle must be exactly equal to the number that grid cells contain.
Example, no "4" would contain 1X4, 2X2 or 4X1 rectangle
The name rectangle can be meant squares too

== Spiral Galaxies ==
Draw along some grid lines to form regions
Each region must contain exactly one circles
Each region must be symmetrical in such a way that if rotated 180 degrees around its circle then it would look exactly the same
Each cells must be in exactly one region

== Rooms ==
Each grid cells is considered to be a room
Draw along some grid lines to build walls
Build a wall that when standing in a room with a number in it, you can see that many rooms by looking along the row or column and DO NOT include the room itself
All room are connected together so that walled off rooms or sections cannot be created

== Carpet set ==
Draw borders along some grid lines to divide the grids into set of rectangles such that each number is inside exactly one rectangle
The number inside each rectangle must be exactly equal to the number of grid cells that rectangle contains, for example "4" could be in 1X4, 2X2 and 4X1 rectangle
Not all cells are necessarily contained within a rectangle
Note that term rectangle includes 'square' too

== Sum Borders ==
Draw borders along some grid lines to divide the grids into set of rectangles such that each number is inside exactly one rectangle
All cells are within exactly one rectangle
The number inside each rectangle must be exactly equal to the sum of the width and height of that rectangle, measured in cells. For example '5' could be within 1X4,2X3,3X2 or 4X1 rectangles.```
