About the game
"Sudoku Killer" is a combination of two puzzles "Sudoku" and "Kakuro". Also known as sumsudoku or killerdoku. Outwardly, it is similar to Sudoku, but there are additional areas in which the sum of numbers must equal a given number, as in Kakuro. The game develops logic and mathematical abilities. There are 1500 levels of varying difficulty. There are many settings that will allow you to adapt the game interface to your gaming style. Control is available using mouse, keyboard and touchscreen.
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.
