10 Tips brainbashers killer sudoku

Killer Sudoku, also known as "Sumdoku," is a puzzle that combines elements of regular Sudoku and Kakuro (a number crossword puzzle). Like in a standard Sudoku puzzle, each row, column, and nonet (a 3x3 grid) in a Killer Sudoku puzzle must contain all of the digits from 1 to 9. However, in a killer Sudoku puzzle, a set of adjacent cells known as a "cage" contains a hint in the form of a number and an operator (such as + or -). This hint tells you the sum of the digits within the cage, and can be used to help you solve the puzzle.

To solve a killer Sudoku puzzle, you must first identify the cages and their corresponding hints. You can do this by looking for groups of adjacent cells that are separated by bold or colored lines. Once you have identified the cages, you can start filling in the cells with numbers. As you fill in the cells, you should pay attention to the following rules:

Each row, column, and nonet must contain the digits from 1 to 9, with no repetition.

The digits within a cage must add up to the hint provided for that cage.

Each cage must have unique digits

The best way to start solving a Killer Sudoku puzzle is to look for the cages with the smallest hints first. These cages will usually have only one or two cells, and it will be relatively easy to fill them in. Once you have filled in the small cages, you can move on to the larger ones. As you fill in more and more cells, you will start to see patterns emerging, and it will become easier to fill in the remaining cells.

You can also use logic based techniques such as:

Single possibility

Last digit possibility

Interaction between cages

and so on

One of the key strategies in solving a killer Sudoku puzzle is to look for interactions between cages. For example, if you know that a certain row contains the digits 2, 4, and 6, then you can eliminate the possibility of these digits appearing in other cages in that row. Similarly, if you know that a certain column contains the digits 1, 3, and 9, then you can eliminate the possibility of these digits appearing in other cages in that column.

As you get more familiar with the different types of cages and their hints, you will start to develop your own solving strategies. With practice, you will be able to solve even the most challenging killer Sudoku puzzles with ease.

In summary, Killer sudoku is a variant of the popular puzzle game Sudoku which adds an extra layer of complexity and challenge by requiring you to use the numbers within a set of cells to get a sum. To solve a Killer Sudoku puzzle you must first identify the cages and their corresponding hints, and then use logic and deduction to fill in the cells with numbers. With practice and learning the different solving techniques you'll be able to solve the most challenging Killer sudoku.
