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.

Numbricks is a type of logic puzzle. 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.Numbricks puzzles are similar to Hidato. The most important difference that it is only possible to move 1 node left, right, up, or down.

Sudoku (originally called Number Place) is a logic-based combinatorial number-placement puzzle. 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.

Tatamibari is a logic puzzle invented by Nikoli. A rectangular or square grid contains 3 kinds of symbols: cross, horizontal bar, vertical bar. The goal is to divide the grid into rectangular regions. Each region contains one cell with a symbol. - A region with a cross must be a square. - If a region contains a horizontal bar, the region's width must be greater than its height. - If a region contains a vertical bar, the region's width must be less than its height. - A grid dot must not be shared by the corners of four regions.

Patchwork (also known as "Tatami") consists of a square grid divided into regions ("rooms").Each room must be filled with each of the digits from 1 to the number of cells in the room.Every row and every column must contain the same amount of each digit.Same digits must not be orthogonally adjacent.

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.

Chain Sudoku (also known as "Strimko") consists of a group of circles arranged in a square grid and containing given clues in various places.

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. Consecutive Sudoku Jigsaw are very similar to regular Consecutive Sudoku puzzles. Regular 9x9 Consecutive Sudoku that row and column rules apply, but instead of a 3x3 grid they are nine Jigsaw shapes.

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.Each row, column and jigsaw shape contains all of the digits 1 through 9. 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.

Linesweeper is played on a rectangular grid. The object is to create a single continuous non-intersecting loop that connects the centers of the grid cells. The numbered cells can't be passed through; the number in the cell means how many of the 8 surrounding cells should contain some part of the solution path. (For example, "0" means the 8 surrounding cells can't be passed through at all).
