About game
Mathematical precision meets classic logic in the ultimate brain-teasing challenge known as Sudoku Killer. This clever hybrid blends traditional number placement with the strategic depth of Kakuro, forcing you to calculate sums while respecting standard grid restrictions. Each puzzle forces you to look beyond basic rows and columns to analyze shaded cages where numbers must add up to a specific total. You can utilize the total sum of 45 for each row or square to deduce missing digits through careful subtraction. With 1500 unique levels available, the intensity grows as you progress from simple warm-ups to truly mind-bending brain training sessions. The interface is fully customizable, allowing you to tweak the look and feel to match your personal solving style. Whether you are a casual player or a seasoned math enthusiast, this game offers an unparalleled mental workout. You can test your deduction skills right now for free in your browser with no download required.
How to play
In addition to standard methods for solving Sudoku, based on the fact that there should be no repeating numbers in one group (in rows, columns and squares), in "Sudoku Killer" the fact that the sum of all numbers in them is always equal to 45 is often used when solving. If one group, or several neighboring groups, contains several shaded areas, except for one cell, then you can find out exactly the number in this cell by subtracting the sums of these areas from 45 (or from 90, 135, etc. if you are checking several neighboring groups). Next, put possible candidates in the cells, analyze which candidates can be excluded. Step by step you will completely solve the puzzle.
