Foseruzu ("Four Cells") is a type of logic puzzle published by Nikoli. The goal is to divide the grid into regions of exactly four cells. The number inside a cell represents how many of its four sides are segments of region borders (including the border of the grid).

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.

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 6x6 Sudoku that row and column rules apply, but instead of a 3x2 grid they are six Jigsaw shapes.Each row, column and jigsaw shape contains all of the digits 1 through 6. In all other respects the puzzle works in the same way, but this change in the region shapes introduces new twists into the logic required to solve the puzzle - and often makes it much harder for you to find the next move as a result! Every Jigsaw Sudoku puzzle only ever has one possible solution, and it can always be reached via reasonable logical deduction. In other words, guessing is never required.

Sujikai (literally "diagonal") is a variation of Sudoku. The puzzle consists of a triangular grid of cells containing digits from 1 to 9. The objective is to fill a grid with digits so that each cell contains a digit and no digit is repeated in any column, row and diagonal in any direction. Also, no digit occurs twice in any of the three larger 3 x 3 square regions and any of the three larger triangular regions enclosed by thick borders.

Shikaku (also known as "Divide by Squares", "Divide by Box", "Number Area") is a logic puzzle. It is played on a rectangular grid. Some of the cells 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.

The Battleship puzzle (sometimes called Bimaru, Yubotu, Solitaire Battleships or Battleship Solitaire) is a logic puzzle based on the Battleship guessing game. Each ship occupies a number of contiguous squares on the grid, arranged horizontally or vertically. The boats are placed so that no boat touches any other boat, not even diagonally. Numbers alongside the grid indicate how many squares in a row or column are occupied by part of a ship.In Battleship, an armada of battleships is hidden in a square grid of 11x11 small squares. The armada includes 1 battleship five squares long, 2 battleship four squares long, 2 cruisers three squares long, 3 destroyers two squares long, and 4 submarines one square in size. Sometimes, some of the fragments of the ships are already open as a hint.

Kakuro (auch als "Cross Sums" und "Kakro" bekannt) ist ein logisches Rätsel, ein mathematisches Äquivalent der Kreuzworträtsel. Das Rätsel besteht aus einem Spielbereich von gefüllten und leeren Zellen ähnlich zu einem Kreuzworträtsel. Einige schwarze Zellen enthalten einen diagonalen Schrägstrich von oben links nach unten rechts mit Ziffern darin, die "Hinweise" genannt. Eine Ziffer in der oberen rechten Ecke bezieht sich auf einen "waagerecht" Hinweis und eine in der unteren linken einen "senkrecht" Hinweis. Das Ziel von Kakuro ist, Ziffern von 1 bis 9 in die weißen Zellen einzufügen, um den Hinweis darauf zu summieren. In einem Eintrag kann jedoch keine Ziffer dupliziert werden. Zum Beispiel die Summe von 6 könnten Sie durch 1 und 5, 2 und 4 aber nicht 3 und 3 bekommen. Das Rätselbuch enthält: - 500 Logik Rätsel- Händelbares 6 X 9 Buchformat- 6 Rätsel pro Seite - Optimal für Anfänger und Experten In dem Buch finden Sie eine Beschreibung und Beispiele der Lösungen für alle Rätsel. Das Buch ist für alle, die Logik und mathematische Probleme mögen. Lösen, entwickeln und verbessern.

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.

Futoshiki is a logic puzzle game from Japan. It is also spelled hutosiki (using Kunrei-shiki romanization).The puzzle is played on a square grid, such as 8 x 8. The objective is to place the numbers 1 to 8 (or whatever the dimensions are) such that each row, and column contains each of the digits 1 to 8. Some digits may be given at the start. In addition, inequality constraints are also initially specified between some of the squares, such that one must be higher or lower than its neighbour. These constraints must be honoured as the grid is filled out.

Nurikabe is a logic puzzle ("nurikabe" in Japanese folklore is an invisible wall that blocks roads and upon which delays in foot travel are blamed; other names for the puzzle: "Cell Structure", "Islands in the Stream"). The puzzle is played on a grid, typically rectangular with no standard size. Some cells of the grid start containing numbers. The goal is to determine whether each of the cells of the grid is "black" or "white" according to the following rules: All of the black cells must be connected. Each numbered cell must be part of a white island of connected white cells. Each island must have the same number of white cells as the number it contains (including the numbered cell). Two islands may not be connected. There cannot be any 2 x 2 blocks of black cells.

Tents (also known as "Tents and Trees") is a logic puzzle. The task is a grid of squares, some of them contain trees.

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.

Lighthouses is played on a rectangular or square grid. It contains black cells with numbers ("lighthouses"). The number in the cell represents the number of ships lit by the lighthouse. A ship is lit if it is in the same row or column as the lighthouse, also ships behind other ships or lighthouses. Each ship is lit by at least one lighthouse. The ships are placed so that no ship touches any other ship or lighthouse, not even diagonally.

Foseruzu ("Four Cells") is a type of logic puzzle published by Nikoli. The goal is to divide the grid into regions of exactly four cells. The number inside a cell represents how many of its four sides are segments of region borders (including the border of the grid).
