    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.

    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 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.

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.

    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.
