Sudoku Rules: Fill in the 9x9 grid with numbers 1~9 such that each row, column, and 3x3 box contains each number exactly once.
Irregular Sudoku: Each row, column, and irregularly shaped box contains no repeating digits.
Killer Sudoku: Combines standard Sudoku rules with "killer cages" (dashed-line groups). Each cage shows a sum for its digits, which must also be unique within the cage.
Kendoku (Newdoku/Calcudoku/Mathdoku): Fill an n x n grid with digits 1-n (no repeats per row/column). Groups marked by thick lines show a target number and operation (+, -, ×, ÷) that their digits must satisfy. If no operator is given, any operation applies.
Skyscraper Sudoku: Enhances standard rules with perimeter clues showing visible building counts (taller numbers block smaller ones), while unmarked sides remain unrestricted.
Snow Sudoku: No digit repeats in any horizontal row, left diagonal, right diagonal direction, or within each hexagon.
Necklace Sudoku: The numbers in each row, each column, and each necklace (an area formed by multiple connected circles) are all non-repetitive.
Thermo Sudoku: Numbers must strictly increase from the round bulb end to the flat end of each thermometer shape.
Arrow Sudoku: The number in the circle equals the sum of all numbers along its arrow path.
Clone Sudoku: Using colors to mark multiple identically-shaped clone regions, where numbers in corresponding positions across clone regions must match.
Missing One Sudoku: Each row, column, and box must contain unique numbers, but black cells remain empty without digits.
Odd / Even Sudoku: Cells with circles must contain odd digits, cells with squares must contain even digits.
3D Sudoku: Each 3x3 box, as well as the 9 cells along each colored line, contain unique, non-repeating digits.
Samurai Sudoku: Satisfying the standard Sudoku rules in each of the five independent regions.
Compdoku: Adds symbols such as great than, and the numbers must satisfy the corresponding size relationships.
Fortress Sudoku: Gray fortress cells must contain numbers larger than adjacent white cells.
Kropki Sudoku: Kropki Sudoku: Black dot - ratio of 2; White dot - differ by 1; Others - not satisfy either of these two relationships.
Diagonal Sudoku (X Sudoku): Adds to standard rules by requiring uniqueness of digits in two major diagonals.
