Irregular Blocks (Jigsaws)
Jigsaw puzzle is played the same as Sudoku, except that the grid has Irregular Blocks, also known as cages.
Irregular Blocks Rules:
It is common to add limits on the placement of the digits, beyond the usual row and column. One of the limits is the Diagonal Variant.
Diagonal Variants Rule:
Variants can be combined. For example: the grid can have both Rectangular Blocks and Diagonal Lines. There can also be more than 2 diagonal lines.
Rectangular Blocks and Diagonal Variants Rules:
Overlapping variant consits of several puzzles. Shared blocks are highlighted by a different color. Here are some examples of overlapping Sudokus:
The grid of the Killer Sudoku is covered by cages (groups of cells), marked with dotted outlines. Each cage encloses 2 or more cells. The top-left cell is labeled with a cage sum, which is the sum of all solution digits for the cells inside the cage.

Greater Than (or Less Than) Sudoku has no given clues (digits). Instead, there are "Greater Than" (>) or "Less Than" (<) signs between adjacent cells, which signify that the digit in one cell should be greater than or less than another.
Kakuro is played on a grid of filled and barred cells, "black" and "white" respectively. The grid is divided into "entries" (lines of white cells) by the black cells. The black cells contain a slash from upper-left to lower-right and a number in one or both halves. These numbers are called "clues".
The grid is divided into heavily outlined cages (groups of cells). The numbers in the cells of each cage must produce a certain "target" number when combined using a specified mathematical operation (either addition, subtraction, multiplication or division).
Futoshiki is played on a grid that may show some digits at the start. Additionally, there are "Greater Than" (>) or "Less Than" (<) signs between adjacent cells, which signify that the digit in one cell should be greater than or less than another.
Straights is played on a grid that is partially divided by black cells into compartments. Compartments must contain a straight - a set of consecutive numbers - but in any order (for example: 2-1-3-4). There can also be white clues in black cells.
The Skyscraper puzzle has numbers along the edge of the grid. Those numbers indicate the number of buildings which you would see from that direction if there was a series of skyscrapers with heights equal the entries in that row or column. For example: if the line has 4 cells and if the first number in the cell is 4, you will see only one skyscraper because the 4-floor skyscraper hides the 1-floor, 2-floor, and 3-floor skyscrapers.
Skyscrapers with Parks
The Skyscrapers puzzle can have Parks (empty cells).
Skyscrapers with Parks Rules:
The numbers along the edge of the Sum Skyscraper grid indicate the sum of heights of the visible buildings.
Sum Skyscrapers Rules:
Complete the grid with zeros (0's) and ones (1's) until there are just as many zeros and ones in every row and every column.
