Slitherlink (also known as "Fences", "Loop the Loop", "Dotty Dilemma", "Sli-Lin", "Great Wall of China") is a logic puzzle. Slitherlink is played on a rectangular lattice of dots.Some of the squares formed by the dots have numbers inside them.The objective is to connect horizontally and vertically adjacent dots so that the lines form a single loop with no loose ends.In addition, the number inside a square represents how many of its four sides are segments in the loop.

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.

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.

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.

Skyscrapers consists of a square grid.The goal is to fill in each cell with numbers from 1 to N, where N is the size of the puzzle's side.No number may appear twice in any row or column.The numbers along the edge of the puzzle 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.

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.

Hidoku (from Hebrew: "my puzzle") is a logical puzzle.The goal of Hidoku is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally. In every Hidoku puzzle the smallest and the highest number are presented in the grid. There are more numbers on the board to help to direct the player how to start the solution and to ensure that Hidoku has only a single solution. Hidoku puzzles are similar to Numbrix. The most important difference is that diagonal moves are allowed.

The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", "regions", or "subsquares") 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 unique solution.

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.

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.

Tents (also known as "Tents and Trees") is a logic puzzle. The task is a grid of squares, some of them contain trees. The goal is to place tents in some of the remaining squares, in such a way that the following conditions are met: There are exactly as many tents as trees. The tents and trees can be matched up in such a way that each tent is directly adjacent (horizontally or vertically, but not diagonally) to its own tree. However, a tent may be adjacent to other trees as well as its own. No two tents are adjacent horizontally, vertically or diagonally. The number of tents in each row, and in each column, matches the numbers given round the sides of the grid.

Minesweeper is well-known by the game in Microsoft Windows. The task is to place mines into empty cells in the grid. The digits in the grid represent the number of mines in the neighbouring cells, including diagonal ones.

Tapa is a logic puzzle. The goal is to blacken some cells of the grid. All the black cells form one contiguous region. No 2 x 2 cell area within the grid can contain all black cells. Clue cells with numbers may not be filled in and tell the length of each consecutive black cell block in the eight surrounding cells. If there's more than one digit in a cell, the groups of black cells have to be separated by at least one white cell. Question marks can be used instead of clue numbers. Each question mark can represent any nonzero integer.
