Classic Sudoku Rules apply. Additionally the arrows indicate that the nearest three digits in the row (column) are in ascending or descending order (increasing towards the direction the arrow is pointing towards). If there is no arrow outside a row/column, the nearest 3 digits therein cannot be in either ascending or descending order.

Suguru, also known as Tectonics or Number Blocks, is a Japanese puzzle invented by Naoki Inaba. The goal is to fill a given rectangular grid with numbers, so that every designated area contains a sequence of non-repeating, consecutive numbers, starting from 1 and going up. Also, adjacent (touching) cells should not contain the same number, even diagonally.

The puzzle a 16 x 16 grid made up of 4 x 4 subgrids (called "regions"). Some cells already contain numbers, known as "givens". The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 16 exactly once. Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.

Each puzzle consists of a grid containing blocks surrounded by bold lines. The object is to fill all empty squares so that the numbers 1 to N (where N is the number of rows or columns in the grid) appear exactly once in each row and column and the numbers in each block produce the result shown in the top-left corner of the block according to the math operation appearing on the top of the grid. In CalcuDoku a number may be used more than once in the same block.

Each cell should contain a zero or a one. No more than two similar numbers below or next to each other are allowed. Each row and each column is unique and contains as many zeros as ones.

Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 3x4 region with the numbers 1-12 once. The objective is to fill the grid with numbers from 1 to 12 in a way that the following conditions are met: Each row, column, and nonet contains each number exactly once. The sum of all numbers in a cage must match the small number printed in its corner. No number appears more than once in a cage.

Shikaku is played on a rectangular grid. Some of the squares in the grid are numbered. The objective is to divide the grid into rectangular and square pieces such that each piece contains exactly one number, and that number represents the area of the rectangle.

Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 5x2 region with the numbers 1-10 once. The difference is how you arrive at those numbers.The objective is to fill the grid with numbers from 1 to 10 in a way that the following conditions are met: Each row, column, and nonet contains each number exactly once.The sum of all numbers in a cage must match the small number printed in its corner.No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 10 cells.

The solver is given a 9x9 grid, partially divided by black cells into compartments. Each compartment, vertically or horizontally, must contain a straight - a set of consecutive numbers, but in any order. For example: 7, 6, 4, 5 is valid, but 1, 3, 8, 7 is not. Like sudoku, the solver must fill the remaining white cells with numbers 1 to 9 (or 1 to n in puzzles with N cells per side) such that each row and column contains unique digits. Whereas Sudoku has the additional constraint of 3x3 boxes, in Str8ts rows and columns are divided by blacks cells. Additional clues are set in some of the black cells - these numbers remove that digit as an option in the row and column. Such digits do not form part of any straight.

Numbricks puzzles are similar to Hidato. The most important difference is that it is only possible to move 1 node left, right, up, or down. It is played on a rectangular grid of squares. Some of the cells have numbers in them. The object is to fill in the missing numbers, in sequential order, going horizontally and vertically only. Diagonal paths are not allowed.

Hitori is played with a grid of squares or cells, with each cell initially containing a number. The objective is to eliminate numbers by blacking out some of the squares until no row or column has more than one occurrence of a given number. Additionally, black cells cannot be adjacent, although they can be diagonal to one another. The remaining numbered cells must be all connected to each other.

The rules of Jigsaw Sudoku are similar to standard Sudoku, since you must place each of the numbers 1 to 9 (or 1 to whatever the size of the puzzle is) into each of the rows and columns. However whereas standard Sudoku also has rectangular boxes that must each contain every number, in Jigsaw Sudoku these boxes are replaced by different bold-lined shapes that must each contain every number instead.

Each puzzle consists of a blank grid with sum-clues in various places. The object is to fill all empty squares using numbers 1 to 9 so the sum of each horizontal block equals the clue on its left, and the sum of each vertical block equals the clue on its top. In addition, no number may be used in the same block more than once.

(This is the standard rule for killer sudokus, and implies that no cage can include more than 9 cells.

Each of the numbers 1 to 9 must appear exactly once in each row, column, and block. In addition, adjacent cells must obey any "greater than" (>) or "less than" (

Place numbers in the grid such that each row, column and 3x3 box contain the numbers 1 to 9. Outside cells must be inserted in one of the first three cells of the row or column.

Jigsaw Samurai Sudoku puzzles consist of five overlapping Jigsaw Sudoku grids. You must place each of the numbers 1 to 9 into each of the rows and columns. Are allocated by different bold-lined shapes that must each contain every number instead.

Each puzzle consists of a 6x6 grid containing given clues in various places. The object is to fill all empty squares so that the numbers 1 to 6 appear exactly once in each row, column and 3x2 box.

Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 4x2 region with the numbers 1-8 once. The difference is how you arrive at those numbers.The objective is to fill the grid with numbers from 1 to 8 in a way that the following conditions are met: Each row, column, and nonet contains each number exactly once.The sum of all numbers in a cage must match the small number printed in its corner.No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 8 cells.

Each puzzle consists of a 12x12 grid containing given clues in various places. The object is to fill all empty squares so that the numbers 1 to 12 appear exactly once in each row, column, diagonal and 3x4 box.

Suguru, also known as Tectonics or Number Blocks, is a Japanese puzzle invented by Naoki Inaba. The goal is to fill a given rectangular grid with numbers, so that every designated area contains a sequence of non-repeating, consecutive numbers, starting from 1 and going up. Also, adjacent (touching) cells should not contain the same number, even diagonally.

Binary (also known as "Takuzu", "Tohu wa Vohu") is played on a rectangular or square grid. The goal is to fill in the grid with digits "0" and "1" according to the following rules: Each box should contain a zero or a one.No more than two similar numbers next to or below each other are allowed.Each row and each column should contain an equal number of zeros and ones (or one more for odd sized grids).Each row is unique, and each column is unique.
