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.

Place numbers of the given range in the grid 6x6 such that every row and column contains each number exactly once. Inequality constraints must be satisfied. The open end of the sign denotes the greater number.

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.

Maze is a puzzle consisting of a complicated network of paths or passages. The aim is to find a path between two selected points.

Fill the empty cells in such a way they build a chain of consecutive numbers from 1 to the marked largest number. All cells with consecutive numbers must touch each other either horizontally, vertically or diagonally.

Place a digit from 1 to 9 into each of the empty cells so that each digit appears exactly once in each row, column and 3x3 outlined box. Additionally every main/marked diagonal contains only 3 different numbers

Place numbers of the given range in the grid 7x7 such that every row and column contains each number exactly once. Inequality constraints must be satisfied. The open end of the sign denotes the greater number.

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.

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.

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.

Each puzzle consists of a 9x9 grid containing given clues in various places. The object is to fill all empty squares so that the numbers 1 to 9 appear exactly once in each row, column, diagonal and 3x3 box.

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 challenge is to paint each cell black or white, subject to the following rules: Each numbered cell must be part of a white island of connected white cells.All of the black cells must be connected.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.

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.

Slitherlink is a logic puzzle 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 simple loop with no loose ends. In addition, the number inside a square represents how many of its four sides are segments in the loop.
