Onregelmatige blokken (jigsaw)
Jigsaw puzzle is played the same as Sudoku, except that the grid has Irregular Blocks, also known as cages. Irregular Blocks Rules:

Diagonal Variants
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:

Combined Variants
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:

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. Greater Than / Less Than Rules:

Kakuro
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". Kakuro Rule:

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). Kalkuldoku Rules:

Futoshiki
Futoshike wordt gespeeld op een veld dat al een aantal cijfers kan bevatten. Aanvullend zie je "groter dan" (>) en "kleiner dan" (<) tekens tussen de aangrenzende velden. Deze betekenen dat het getal in het ene veld groter of kleiner moet zijn als dat in het andere veld. Futoshiki regels:

Straights
Straten (Straights) hebben een veld dat met zwarte vakjes is onderverdeeld in gedeeltes. Elk gedeelte moet een straat bevatten - een reeks opvolgende nummers - maar de volgorde is willekeurig. Bijvoorbeeld: 2-1-3-4). Er kunnen ook witte aanwijzingen in de zwarte cellen staan. Straten regels:
|
Skyscraper
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 Rules:

Skyscrapers with Parks
The Skyscrapers puzzle can have Parks (empty cells). Skyscrapers with Parks Rules:
|
Sum Skyscrapers

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. Binary Rules:
|
