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 classic 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: 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: Perimeter clues showing visible building counts (taller numbers block smaller ones), while unmarked sides remain unrestricted.
