Rekuto is played on a rectangular or square grid. Some of the cells have numbers in them. The aim is to divide the grid into rectangular and square pieces such that each piece contains exactly one number, and that number represents the sum of the width and height of the rectangle.

The binary puzzle (also known as "Binairo", "Takuzu", "Tohu wa Vohu") is a new logic puzzle that you can solve by using only zeros and ones. The rectangular or square grid should fill the numbers in accordance with the following rules: - Each row and each column contain the same number of digits "1" as digits "0" (or one more for odd sized grids). - The same number can only be in no more than two cells in a row. - Each line must be unique, and each column must be unique.

Sudoku (also known as "Number Place") is a placement puzzle.The puzzle is most frequently a 9 x 9 grid made up of 3 x 3 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 9 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. In Consecutive Sudoku ("1-away Disallowed Number Place"), all the places where orthogonally adjacent cells are consecutive numbers have been specially marked.

Killer Sudoku (also called "Sums Sudoku", "Sums Number Place", "Samunamupure", "Kikagaku Nampure") is a puzzle that combines elements of Sudoku and Kakuro. Despite the name, the simpler killer sudokus can be easier to solve than regular sudokus, depending on the solver's skill at mental arithmetic, the hardest ones, however, can take hours to crack. In Killer Sudoku, sub-regions have specified sums, and no number can be repeated within a region.

Seethrough (also known as "Doors", "Open Office") is a logic puzzle, where every cell denotes a "room". The aim is to close some "doors" between rooms. Open doors allow to look into other rooms. The number in the cell indicates the total number of rooms visible in horizontal and vertical direction from that room (the room itself excluded). There can be no isolated rooms; this means that you should be able to reach all rooms by moving horizontally and vertically.

Straights is a logic puzzle. It is a 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: 2-1-3-4). The aim is to fill all white cells with the numbers from 1 to N (where N is the size of the grid). No single number can repeat in any row or column. Clues in black cells remove that number as an option in that row and column, and are not part of any straight.

Kuromasu (from Japanese "kuromasu wa doko da", literally "Where is Black Cells?"; also known as "Kurodoko") is played on a rectangular grid. Some of these cells have numbers in them. Each cell may be either black or white. The object is to determine what type each cell is. The following rules determine which cells are which: - Each number on the board represents the number of white cells that can be seen from that cell, including itself. A cell can be seen from another cell if they are in the same row or column, and there are no black cells between them in that row or column. - Numbered cells may not be black. - No two black cells may be horizontally or vertically adjacent. - All the white cells must be connected horizontally or vertically.

Sudoku (also known as "Number Place") is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. Sohei Sudoku - 4 sudoku puzzles that has two overlapping areas. All grids must solved according to sudoku rules.

Clouds (also known as "Rain Clouds", "Radar") is a variant of Battleship puzzle. The task is to mark certain cells of the rectangular grid as belonging to a cloud. Clouds occupy an area of rectangular shape and their width and height is at least two cells. No clouds touch each other, not even diagonally. Numbers outside the grid show the quantity of cells occupied by clouds in corresponding row or column.

Mochikoro ("Mochinuri") is a logic puzzle. It consists of a grid, with numbers in some cells. The aim is to blacken some cells of a grid according to the following rules: - The black cells divide the grid in rectangular areas ("islands") of white cells. - No two islands may share an edge, but all of the islands must be connected to each other through their corners. - Each numbered cell must be a part of a white island. Some white areas may not include a cell with a number. - Each island must have the same number of white cells as the number it contains (including the numbered cell). - No 2 x 2 cell area within the grid can contain all black cells.

Each triangle must occupy exactly half of its cell, but may be in one of four orientations. Every contiguous white region must be a rectangle or a square. A number in a black cell indicates how many triangles are adjacent to that cell by sides.

Masyu is a type of logic. The purpose of its creation was to present a puzzle that uses no numbers or letters and yet retains depth and aesthetics. Masyu is played on a rectangular grid of squares, some of which contain circles, each circle is either "white" (empty) or "black" (filled). The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells. The loop must "enter" each cell it passes through from the center of one of its four sides and "exit" from a different side, all turns are therefore 90 degrees. The two varieties of circle have differing requirements for how the loop must pass through them: - White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path. - Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.

Fillomino (also known as "Polyominous") is a type of logic puzzle. It is played on a rectangular grid of squares. Some cells of the grid start containing numbers, referred to as "givens". The goal is to divide the grid into blocks. The block must contain the number of cells indicated by the number in the cells of the block. The block cannot touch a similarly sized block, horizontally or vertically. Cells without numbers may form blocks necessary to complete the puzzle.

Sudoku Jigsaw (also known as "Irregular", "Nonomino" or "Geometric Sudoku") is a logic-based, combinatorial number-placement puzzle. Jigsaw Sudokus are very similar to regular Sudoku puzzles.Regular 9x9 Sudoku that row and column rules apply, but instead of a 3x3 grid they are nine Jigsaw shapes.
