About Sudoku Killer / 杀手数独
Sudoku (数独 sūdoku, digit-single) - 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", or "regions") contains all of the digits from 1 to 9.
Killer Sudoku puzzles include all the rules of regular Sudoku but add in dashed-line 'cages' which must sum to given values. Killer Sudoku is also sometimes known as Sumdoku, Mathdoku or Addoku.
The name 'Killer' Sudoku arises because of the wicked twist on the standard Sudoku puzzle, since you must not only place each of the numbers 1 to 9 (or 1 to the size of the puzzle) into each of the rows, columns and bold-lined 3x3 (or other size) boxes but you must also place the numbers into each dashed-line cage so that they add up to its given total - and without repeating a digit in a dashed-line cage. ©

Sudoku Killer, developed by Konstructors and published by Hook Games, is a thoughtfully constructed digital adaptation of one of the most demanding Sudoku variants, designed for players who relish logical and mathematical challenges. It takes the familiar grid-based logic of traditional Sudoku and transforms it with an additional layer of arithmetic reasoning. Each puzzle features the standard nine-by-nine format, where every row, column, and three-by-three block must contain the numbers one through nine, but the twist comes in the form of “cages”—dotted-line groups of cells with specific sum totals. These cages must satisfy their arithmetic requirement without repeating any numbers inside them. The result is a hybrid puzzle that tests both logical deduction and numerical calculation, appealing to players who enjoy more intricate reasoning than what a typical Sudoku provides. The game’s design is clean, understated, and focused entirely on sharpening the player’s problem-solving instincts. From the moment it begins, Sudoku Killer establishes a sense of calm focus. The interface is minimalist, with a clear layout that allows players to concentrate entirely on the puzzle itself. The…
